How to Assess and Improve All Aspects of Your Fitness

You can be strong and still have poor endurance. You can run impressive distances and still lack muscle mass or struggle to control a basic squat. Being good at one form of exercise does not automatically mean you are well rounded.

Most exercise goals fall into two categories: appearance and function. You might want to build muscle, get leaner, lift more weight, run a faster 5K, or simply have more energy throughout the day. The challenge is achieving those goals while maintaining the capacity to move and perform for years to come.

That starts with knowing what to assess. Rather than asking, “Am I fit?” a more useful question is, “Which part of my fitness is limiting me?” A practical testing framework can reveal those limitations and help you decide where your training effort will have the greatest return.

The Nine Components of Physical Fitness

Exercise produces different adaptations. Dr. Andy Galpin organizes them into nine broad categories:

1. Skill or technique: How effectively you perform a movement, whether that is squatting, running, or swinging a golf club.
2. Speed: How quickly you move, including acceleration and maximum velocity.
3. Power: How quickly you produce force. Power combines force and velocity.
4. Strength: The maximum force you can produce in a single effort.
5. Hypertrophy: Muscle growth and the amount of muscle you carry.
6. Muscular endurance: The ability of a muscle or muscle group to repeat or sustain work.
7. Anaerobic capacity: The ability to perform very demanding, short-duration work, roughly 30 seconds to two minutes.
8. Maximum aerobic capacity: Your capacity to take in and use oxygen during demanding exercise, commonly assessed through VO2 max testing.
9. Long-duration endurance: The ability to sustain submaximal work continuously, generally for at least 20 minutes.

These categories overlap, but they are not interchangeable. A push-up test mainly reflects local muscular endurance in the chest, shoulders, and triceps. It does not establish your overall cardiovascular endurance. Likewise, a high maximum heart rate is not the same thing as a high VO2 max.

The benchmarks below are practical screening targets from Galpin’s framework, not universal clinical cutoffs. Age, sex, body size, exercise experience, equipment, and technique all affect interpretation. Their purpose is to identify substantial gaps, not to turn every result into a pass-or-fail judgment about your health.

1. Movement Skill: Assess How Well You Control Your Body

Movement quality comes first because it affects your ability to train consistently. A qualified physical therapist or movement specialist can assess your movement patterns in detail. If that is available to you, it is the best starting point.

For a simple self-assessment, record representative exercises from the front and side. Choose movements you actually use, ideally covering four patterns:

• Upper-body push: A push-up or bench press.
• Upper-body pull: A pull-up or bent-over row.
• Lower-body push: A squat.
• Lower-body pull: A deadlift.

Perform about three to 10 slow, controlled repetitions from each angle. Examine the major joints, including the shoulders, elbows, lower back, hips, knees, and ankles.

Look for four things

• Symmetry: Does one side move differently? Does one hip shift, one elbow flare, or one limb travel farther than the other?
• Stability: Can you control the movement without substantial shaking or unexpected shifts? Can you pause in a position rather than immediately bouncing out of it?
• Awareness: Do you understand what the movement requires? Sometimes a simple cue corrects an apparent limitation.
• Range of motion: Can the relevant joints move through an appropriate range without another part of the body compensating?

Awareness matters more than people often realize. Someone whose heels lift during a squat may not have a fixed mobility problem. They may simply not know that they should keep their feet grounded. If a clear instruction immediately corrects the movement, that is different from being unable to achieve the position.

During a squat, for example, look for the knees moving forward while the feet remain flat and the rest of the body stays controlled. The question is not whether every person looks identical. It is whether you can access and control the movement without a major compensation.

Use a simple movement score

Galpin uses an intentionally simple scoring system:

• 0: A major limitation makes the exercise inappropriate for maximal testing or substantial loading.
• 1: A minor flaw calls for caution with load and volume.
• 3: The movement is sufficiently controlled to proceed with reasonable training, even if it is not perfect.

This is a screen, not a diagnosis. You are looking for obvious problems that deserve attention, not trying to become your own movement specialist. For additional exercise demonstrations, the American Council on Exercise’s exercise library provides a useful reference.

2. Speed: Test It When It Serves a Specific Goal

Pure speed testing is not necessary for most people seeking general health and fitness.

For an athlete, a timed sprint such as a 40-yard dash may be useful. In a weightlifting setting, a velocity transducer can measure how quickly a barbell moves. Those assessments answer specific performance questions about acceleration or maximum velocity.

If neither of those qualities is central to your goals, you do not need to force a speed test into your annual assessment. Other tests will usually provide more actionable information.

3. Power: Use a Standing Broad Jump

A standing broad jump is a simple way to screen lower-body power without specialized equipment.

1. Stand with your toes behind a marked line.
2. Jump forward as far as possible from a stationary start. You can use an arm swing, but not a running approach.
3. Measure from the starting line to the back of the heel closest to it.

Use the shorter distance if one foot lands farther forward than the other. That keeps the measurement consistent rather than rewarding an uneven landing.

A rough target is a jump equal to your height. Someone who is 6 feet tall would aim to jump about 6 feet. Galpin adjusts that target downward by approximately 15% for women.

This is a broad screening benchmark, not an athletic performance standard. Highly trained power athletes may jump much farther. The point here is to identify a substantial limitation, not to compare yourself with a professional football player.

4. Strength: Assess Grip and Lower-Body Force

Strength is the maximum force you can produce, not the number of repetitions you can tolerate. Assessing more than one region gives you a better picture than relying on a single favorite lift.

Grip strength with a dynamometer

A handgrip dynamometer measures squeezing force, usually in kilograms. Test both hands.

Galpin’s general screening targets are:

• Men: Approximately 40 kilograms or more, with more than 60 kilograms representing a strong result in this framework.
• Women: Approximately 35 kilograms or more.
• Side-to-side difference: Ideally no more than about 10%.

Your nondominant hand should not automatically be much weaker. Dominance is partly about precision, such as writing, rather than simply maximal force.

Grip endurance with a dead hang

If you do not have a dynamometer, hanging from a pull-up bar provides another useful screen. Choose a bar thin enough to wrap your hands around securely.

• 30 seconds: A useful minimum target.
• 30 to 50 seconds: A reasonable result with room for improvement.
• More than 60 seconds: A strong result in this framework.

A dead hang is not identical to a dynamometer test, and body weight matters considerably. Holding 240 pounds is a different task from holding 145 pounds. Treat the time as context-dependent rather than a perfectly scaled comparison between people.

Lower-body strength with a leg extension

A barbell back squat can be an excellent strength assessment for an experienced lifter, but it is technically demanding and requires appropriate setup and spotting. A leg-extension machine is often more practical for a general fitness assessment.

A rough target is the ability to perform a leg extension with a load equal to your body weight. Galpin allows that target to decrease by about 10% per decade after age 40. Because machines differ, comparisons are most useful when you return to the same equipment.

You do not have to perform a true one-repetition maximum. An alternative is to use a heavy load you can lift for fewer than five repetitions, then enter the load and repetitions into a one-rep-max estimator.

The farther you move beyond five repetitions, the less useful that estimate becomes for assessing maximum strength. A set of 12 is increasingly influenced by muscular endurance.

An alternative: A loaded squat hold

A front-loaded squat hold can provide information about lower-body strength, positioning, trunk control, and lower-back stability.

• Introductory target: Hold approximately one-third of your body weight at the bottom of a squat for 30 seconds.
• More demanding target: Hold approximately half your body weight for 45 seconds.

Use a kettlebell or dumbbell held in front of your chest. Maintaining a sound position is the priority. In this particular assessment, Galpin places more emphasis on holding that position without technical breakdown than on completing the return to standing.

Two rules for every strength test

First, technique comes before maximum effort. Do not test to exhaustion or attempt maximal loads in an exercise you cannot perform confidently. Choose a more appropriate movement instead.

Second, standardize your warm-up. The preparation you do before testing can substantially change your result. If you want to compare this year with next year, the warm-up needs to be comparable too.

5. Muscle Mass: Look Beyond Appearance

How much muscle you want for aesthetic reasons is a personal choice. Whether you carry enough muscle to support health and function is a separate question.

Body-composition testing can help assess that. Options include a DEXA scan or bioelectrical impedance testing. One useful metric is fat-free mass index, or FFMI, which relates fat-free mass to height.

An FFMI calculator generally requires three inputs:

• Body weight.
• Body-fat percentage.
• Height.

Galpin’s general targets are approximately 20 or higher for men and 18 or higher for women. He flags values below roughly 17 for men and 15 for women as particularly concerning for insufficient fat-free mass.

These are working benchmarks, not a diagnosis. FFMI reflects fat-free tissue rather than directly measuring muscle alone, and its interpretation depends on the quality of the body-composition estimate.

Body fat also matters. A high FFMI does not automatically indicate a favorable overall body composition. Galpin’s interpretation assumes body fat below roughly 30% for men and 35% for women. A man with an FFMI around 24 or 25 may carry considerable muscle, but the same number alongside very high body fat does not tell the same story.

6. Muscular Endurance: Test Repeated and Sustained Work

Muscular endurance is local. A strong push-up result does not tell you much about your legs, and a strong leg-endurance result does not establish your trunk endurance. Use more than one movement when possible.

Planks and push-ups

Simple screening targets include:

• Front plank: 60 seconds.
• Side plank: 45 seconds.
• Push-ups for men: More than 25 consecutive repetitions.
• Push-ups for women: More than 15 consecutive repetitions.

For push-ups, use full elbow extension at the top and bring the chest to, or close to, the ground at the bottom. If you use a different version, record it and repeat that same version later.

In Galpin’s framework, five to 15 push-ups for women indicates room for improvement, while fewer than five deserves more attention. The broader principle applies to everyone: very limited capacity in a basic movement is more informative than whether you narrowly miss an ambitious target.

Repeat your strength test at 75% of maximum

Another approach is to use the same exercise you selected for strength testing. Load it to approximately 75% of your measured or estimated maximum, then perform as many technically sound repetitions as possible.

If your leg-extension maximum is 200 pounds, for example, the endurance test would use 150 pounds. More than eight repetitions is Galpin’s general target.

This helps separate two problems that can look similar. You may have good maximum strength but limited ability to repeat efforts, or you may have reasonable endurance with relatively little maximum force.

7. Anaerobic Capacity: Assess Short, Hard Efforts

Anaerobic-capacity testing asks how much work you can produce during a brief, highly demanding effort.

In a laboratory, common approaches include:

• The Wingate test: A 30-second maximal cycling effort.
• The Bosco protocol: Repeated vertical jumps performed as high and quickly as possible for approximately 60 seconds, measured with a force plate.

Outside a laboratory, a hard effort on an air bike or rowing machine can serve as a practical comparison point. Sprinting is another option when it is appropriate for your experience and movement capacity.

The important requirement is that technique should not become the limiting factor. A technically complex movement, such as a kettlebell swing, introduces too many other variables when the goal is to assess maximal work under substantial fatigue.

Depending on the protocol, an effort might last 30, 45, or 60 seconds. There is no single distance or work-output target that transfers cleanly between a rower, an air bike, and a running track. Choose a repeatable protocol and compare your performance under the same conditions.

Maximum heart rate is not a fitness score

The familiar estimate of maximum heart rate is 220 minus your age. For a 50-year-old, that gives approximately 170 beats per minute.

That is an extremely rough estimate. Exceeding it does not prove superior fitness, and falling short does not prove poor fitness.

Galpin places more practical emphasis on heart-rate recovery: how quickly your heart rate falls after the effort. His rough first-minute target is a decrease of about 30 beats per minute, equivalent to an average of half a beat per second. He also discusses following recovery into the second and third minutes, with an approximate cumulative decrease of 60 beats by two minutes.

Treat those as rough observations within a consistent testing protocol, not standalone diagnostic thresholds. Heart-rate recovery adds cardiovascular information, but it is not a direct measurement of anaerobic work capacity.

8. VO2 Max: Assess Maximum Aerobic Capacity

VO2 max describes the maximum rate at which your body can take in and use oxygen during exercise. It is typically expressed in milliliters of oxygen per kilogram of body weight per minute, written as mL/kg/min.

A laboratory test measures respiratory gases through a mask while exercise intensity increases. That is the reference approach. Reaching maximum heart rate alone does not establish that you have measured VO2 max.

For practical testing outside a laboratory, there are two useful options.

The 12-minute Cooper test

Cover as much distance as you can in 12 minutes, then enter the distance into a Cooper-test calculator to estimate VO2 max. The Cooper Institute provides further context on fitness assessment and aerobic fitness.

This is a sustained best effort over the full 12 minutes, not an attempt to maintain an all-out short-sprint pace. The test belongs in the broader category of demanding aerobic efforts that last several minutes, often approximately eight to 15 minutes.

The Rockport one-mile walk test

If running is not appropriate or appealing, the Rockport test offers a submaximal alternative:

1. Walk one mile using the test protocol.
2. Record your completion time.
3. Record your heart rate at the finish.
4. Enter those measurements and the calculator’s other required information into a Rockport-test calculator.

This can be particularly useful when running is limited by knee discomfort, back discomfort, or current fitness. Follow the chosen protocol carefully so that the estimate is meaningful.

VO2 max targets

Galpin’s broad minimum targets are approximately:

• Men: 35 mL/kg/min.
• Women: 30 mL/kg/min.

His higher performance aspirations are above 50 for men, with above 55 as a particularly desirable result, and above 50 for women.

Those higher numbers are ambitious targets, not minimum requirements for everyone. Age, sex, testing method, and training history belong in the interpretation.

9. Long-Duration Endurance: Can You Keep Going?

This assessment is deliberately simple: Can you maintain a consistent work output for at least 20 minutes without stopping?

Pick something that fits your life, such as a familiar route or a repeatable cycling or rowing session. The usual range is about 20 to 60 minutes, although longer efforts also fall within this category.

The distinction is continuous work. There should be no intervals, repeated breaks, or substantial reductions in output.

For someone with a very low starting fitness level, walking continuously for 30 minutes may be a meaningful challenge. For someone already reasonably fit, use something more demanding than ordinary walking.

Galpin likes an additional challenge: sustaining the effort while breathing only through the nose. Consider that an optional variation, not the definition of endurance. The core assessment remains whether you can keep working continuously.

How to Organize Your Fitness Testing

A full assessment does not have to take over your training calendar. Galpin recommends completing the battery approximately once a year, ideally when you are about to adjust your training priorities.

You can fit it into two days, but three days is generally more practical. Testing is still physical work. You are not losing a week of exercise by setting aside time to understand what your exercise should address.

Start fresh

Schedule body-composition testing before demanding exercise, ideally after about 48 hours without hard training. Acute exercise can affect measurements through changes in fluid storage and inflammation.

Assess movement quality while fresh as well. A squat assessment performed while severely sore may tell you more about yesterday’s workout than your usual movement capacity.

Put low-fatigue tests before exhausting tests

The general order is:

1. Movement assessment and other skill-based work.
2. Power testing.
3. Maximum-strength testing.
4. Muscular-endurance testing.
5. Highly fatiguing conditioning work.

A broad jump creates relatively little fatigue, so it can precede strength testing. You can then assess leg-extension strength, rest approximately five to seven minutes as needed, and perform the endurance test at 75% of maximum.

The same session can include grip and upper-body assessments, provided earlier tests do not undermine later results.

A practical three-day arrangement

• Day 1: Body composition, movement quality, broad jump, grip strength, lower-body strength, and muscular endurance.
• Day 2: Long-duration endurance and anaerobic testing, arranged so fatigue does not compromise the result you care about most.
• Day 3: VO2 max testing.

Long-duration work and anaerobic testing can also be separated if combining them makes the results less interpretable. VO2 max testing generally deserves its own day because it is demanding.

Whatever schedule you choose, record the details: equipment, warm-up, exercise variation, range of motion, rest periods, and test order. A repeatable assessment is more valuable than a precise-looking number obtained under different conditions every time.

Use the Results to Improve Your Training

You do not need to maximize all nine components. The goal is to avoid a severe limitation that holds everything else back.

Galpin calls these limitations “performance anchors.” You might love endurance training but have very little strength. You might love lifting but be unable to sustain continuous work. You might have plenty of muscle but lack control in a movement you load heavily.

Those are useful findings. They give you a direction:

• Major movement limitations: Address technique and control before increasing load or fatigue.
• Low strength or muscle mass: Give those adaptations more attention in your training priorities.
• Poor muscular endurance: Recognize that maximum-strength work alone may not address repeated-effort capacity.
• Limited aerobic or long-duration capacity: Make room for conditioning rather than assuming resistance training covers every requirement.

The point is not to abandon the activity you love. If running is what motivates you, keep running. If lifting is your passion, keep lifting. Bring the weakest areas up to a sufficient level so they do not limit your ability to pursue the goals that matter most.

Good fitness testing does not simply tell you how you performed. It tells you what deserves your attention next.
