How to Assess Fitness: 9 Tests That Work

Learn how to assess fitness with nine practical tests for strength, power, VO2 max and endurance, each with clear pass numbers you can use.

The Nine Components of Physical Fitness

Physical fitness breaks into nine measurable adaptations: movement skill, speed, power, strength, muscle hypertrophy, muscular endurance, anaerobic capacity, maximal aerobic capacity (VO2 max) and long-duration endurance. Exercise physiologist Professor Andy Galpin presented this framework in a Huberman Lab Essentials episode with Andrew Huberman, a professor of neurobiology and ophthalmology at Stanford School of Medicine.

The nine components are not equal in how you test them. Speed and power need explosive effort, strength needs heavy loads, and the endurance qualities need timed efforts of 30 seconds to an hour. The table below summarizes each component and its primary assessment method.

Component	What it measures	Primary test	Target
Movement skill	Symmetry, stability, range of Notion	Recorded squat, press, pull, hinge	0-3 score, no red flags
Power	Force times velocity	Standing broad jump	Jump your height (about 15% less for women)
Strength	Maximal force	Grip dynamometer, leg extension	40 kg grip (men); leg extension at body weight
Hypertrophy	Muscle mass	DEXA scan, FFMI	FFMI 20+ (men), 18+ (women)
Muscular endurance	Repeated submaximal reps	Push-ups, plank, 75% load test	25 push-ups (men), 15 (women)
Anaerobic capacity	30-120 s all-out work	Wingate or field sprint	30 bpm heart rate drop in 60 s
VO2 max	Aerobic ceiling	Cooper 12-minute run test	35+ ml/kg/min (men), 30+ (women)
Long duration	20+ min steady output	Nonstop nasal-breathing session	20-30 min, no breaks

Galpin's key point is prioritization. You do not need to be optimal in all nine areas for good health. You need to eliminate what he calls severe performance anchors: any component so weak that it caps everything else. Move that weak area up to sufficient, then pursue whatever you enjoy.

One component is missing from the table for a reason. Galpin says pure speed, meaning maximum velocity or acceleration, is one most people should not test. Speed work with a 40-yard dash or a barbell velocity transducer belongs to high-performance athletes.

How Do You Test Movement Skill at Home?

You test movement skill by recording four representative exercises from two angles and checking for symmetry, stability, awareness and full range of Notion. The gold standard is a qualified physical therapist, but Galpin offers a free self-screen done joint by joint across the shoulder, elbow, low back, hip, knee and ankle.

Pick an upper-body press, an upper-body pull, a lower-body press and a lower-body pull. A push-up, a pull-up or bent row, a squat and a deadlift cover it. Film a frontal view and a side view, three to ten slow repetitions per angle, then look for four things:

Symmetry: left to right and front to back. Does one hip slide, or one elbow flare differently?
Stability: you control the movement slowly, even pausing three to ten seconds at the bottom of a squat without shaking.
Awareness: many flaws are simply unknown. If someone points out that the heels should stay down, the squat instantly fixes itself.
Range of Notion: each joint moves through a full, uncompromised arc, such as knees traveling over the toes with the whole foot on the floor.

Score each movement on a 0-1-3 scale. Zero means acute injury risk; do not perform the exercise, because you could get hurt on rep one. One means a minor flaw; train it but watch load and volume. Maybe 3 means the movement is perfect or close to it; proceed with a reasonable protocol. The screen takes seconds per movement and costs nothing.

What Is the Simplest Test for Power?

The simplest power test is a standing broad jump, because power is speed multiplied by force and the jump expresses both in one effort. Stand still, swing or bounce as much as you like, and jump forward as far as possible without a running start.

Measure from the starting line at the tip of your toe to the furthest point back where either heel lands. The benchmark: jump at least your own height. If you are five foot five, clear five feet five. Women should aim for roughly 85% of their height, about a 15% reduction, because average power output differs. Elite athletes far exceed this; a six-foot NFL player may jump nine to 11 feet. You are screening for red flags, not optimizing.

How Should You Measure Strength?

You measure strength in at least two areas, and grip is the easiest starting point. Galpin treats grip strength as a whole-body marker worth testing with a hand dynamometer, a device that once cost hundreds of dollars and now runs about $25 to $100 online.

Squeeze with each hand and read the value in kilograms. The targets: men should reach at least 40 kg, ideally above 60; women about 35 kg as the cutoff. Keep left-right variation under 10%. The non-dominant hand is often just as strong, since the dominant hand specializes in precision rather than force.

A dead hang works as a no-equipment alternative. Hang from a thin pull-up bar and hold on. Thirty seconds is the minimum, 30 to 50 seconds is good, and above 60 seconds Galpin is satisfied. The test scales poorly at bodyweight extremes: hanging with 240 pounds is hard even when lean, while a 145-pound person hangs a long time regardless of health.

For lower body strength, Galpin prefers a leg extension test over the barbell back squat because it is standardized and needs no technique work or spotters. The target is one leg extension at your body weight. Past age 40, allow roughly 10% less per decade: at 50 years old and 170 lbs, 160 lbs is a good mark.

You never need a true one-repetition max. Load something near your maximum, do as many reps as you can up to five, and enter the result into any online one-rep-max calculator. For example, three repetitions at 200 lb estimates a one-rep max of about 215. Accuracy degrades quickly past five repetitions, so a 12-rep set will not estimate reliably.

A more functional alternative is a front squat or goblet squat hold. Hold about half your body weight at the bottom position for 45 seconds without technical breakdown. As an entry level, hold a third of your body weight for 30 seconds. Returning to standing is optional; the hold itself tests position, core and low-back control. Two caveats apply to all strength testing: never max out without solid technique, and standardize your warm-up so repeat tests stay comparable.

How Do You Know If You Have Enough Muscle?

You know you have enough muscle when your fat-free mass index (FFMI) clears the health floor, which is a number above 20 for men and 18 for women. FFMI is calculated from total body weight, body fat percentage and height, and any standard online calculator produces the same figure and grading rubric. A DEXA scan is the gold-standard body composition measurement, though bioelectrical impedance works as an approximation.

Galpin separates aesthetics from health here. How much muscle looks good is entirely your call. The health floor is not: men below an FFMI of 17 and women below 15 sit in a zone of severe physiological detriment from insufficient muscle. Above roughly 24 to 25, a reasonably lean man carries a lot of muscle. Those FFMI grades assume sub-30% body fat for men and sub-35% for women; a very large person at 40% body fat with a high FFMI is not in a good spot.

Timing matters for the measurement itself. Acute exercise inflates or distorts body composition readings through inflammation and water storage, so rest for about 48 hours before any scan.

What Counts as Good Muscular Endurance?

Good muscular endurance shows up as 25 or more consecutive push-ups for men and 15 or more for women, with full elbow lockout at the top and the chest touching or nearly touching the floor at the bottom. Below five push-ups is a problem; between five and 15 for women is a gray zone worth improving. Keep the form standard between tests so progress is measurable. A front plank for 60 seconds or a side plank for 45 seconds is another acceptable check.

Muscular endurance is local, not cardiovascular. A push-up test measures the triceps, chest and shoulders, not your heart or lungs, which is why Galpin tests each region separately rather than treating one number as whole-body endurance.

The second option reuses your strength test. Load the leg extension or other strength movement to 75% of your estimated max and do as many repetitions as possible. More than eight reps is the pass mark; eight or fewer signals a muscular endurance problem.

How Do You Test Anaerobic Capacity and Recovery?

You test anaerobic capacity with 30 to 120 seconds of all-out work, because this quality is a whole-body limit on maximum output over short durations, not a single muscle's repeatability. In a laboratory that means a 30-second Wingate test on a bike or a Bosco protocol of maximal vertical jumps on a force plate for 60 seconds, an effort that destroys most people by second 45.

Without a lab, sprint, ride an air bike, or row at maximum effort for roughly 30 to 60 seconds. Choose a movement with no technical failure risk, so avoid kettlebell swings. There are no universal distance standards because a treadmill, a track and an assault bike produce incomparable numbers. What matters is completing the effort near your limit.

The better metric is heart rate recovery. The formula 220 minus age estimates maximum heart rate, but Galpin calls it extremely generic: falling short of it says nothing about your fitness and exceeding it says nothing good. Instead, reach genuine exhaustion, note your peak heart rate, then count the drop. The standard is about half a beat per second: roughly 30 beats per minute down within 60 seconds, about 60 beats within two minutes, and roughly half again by three minutes. So 60 seconds should cut 30 beats, and 60 more seconds should cut another 30. Recovery slower than that flags a problem in anaerobic or cardiovascular capacity.

What Are the Best Field Tests for VO2 Max?

The best field test for VO2 max is the Cooper 12-minute run: run as far as you can in 12 minutes, record the distance, and enter it into an online calculator for an estimated VO2 max. Distance covered typically falls between one and just over two miles depending on fitness. Kenneth Cooper developed the original protocol in 1968, and the test remains the namesake assessment of the Cooper Institute, which he founded that year.

The gentler alternative is the Rockport one-mile walk test, a submaximal option for people with knee or back pain that rules out a 12-minute hard run. Walk one mile as fast as you can, record your time and your heart rate at the finish, and enter both into the standard equation. Done correctly, Galpin considers it reasonably accurate.

The laboratory mask test that measures respiratory gases remains the gold standard. As for targets, Galpin wants men above 35 ml/kg/min as a minimum and women above 30, but he is not satisfied until men exceed 55 and women exceed 50. Those numbers come directly from the Huberman Lab episode discussion.

How Should You Schedule Fitness Testing?

You should run the full test battery about once a year, ideally at the start of the year or whenever your training changes, spread over roughly three days. Long-duration endurance is a pass-fail check, not a number: sustain nonstop work for at least 20 minutes, ideally 30, at a non-walking pace, and Galpin likes the added constraint of nasal breathing only. Walking only counts if 30 uninterrupted minutes of it is genuinely hard for you.

Order the tests by fatigue cost. Non-fatiguing measurements go first and whenever convenient:

Body composition and FFMI first, after 48 hours without hard exercise, because acute training inflates the readings.
Movement skill early, when you are fresh and not sore.
Power, maximum strength and skill tests at the start of a training day, since fatigue destroys them.
Muscular endurance immediately after the strength test it derives from: one-rep-max leg extension, rest five to seven minutes, then 75% for max reps.
Anaerobic capacity on its own day, or after the long-duration test if you want the effort to double as a warm-up.
VO2 max testing on a mostly fresh day, optionally after the movement screen or body composition work.

The goal of the annual battery is a barometer for the next several months of training. Fix severe weak points first, keep training what you love, and repeat. Companion training notes compiled by Dev Doido do canal do youtube are available at crazystack.com.br.

Frequently Asked Questions

How often should I test my fitness?

Run the full battery about once a year, ideally over three days at the start of a training cycle. Individual sub-tests, such as push-ups or a dead hang, can be repeated more often as long as you standardize form and warm-up.

Do I need a true one-rep max to measure strength?

No. Lift a load near your maximum for up to five repetitions and use an online one-rep-max estimator. For example, three reps at 200 lb projects about 215. Accuracy falls off quickly beyond five reps, so a 12-rep set will not give a reliable estimate.

What is a good broad jump distance?

Jump at least your own height from a standing start. Women should target roughly 85% of their height, about a 15% reduction. Elite NFL players jump nine to 11 feet, but the test screens for red flags, not elite performance.

Is walking enough for the long-duration test?

Only if 30 minutes of uninterrupted walking is genuinely challenging for you. Otherwise Galpin wants a non-walking pace maintained for 20 to 30 minutes with no breaks, ideally breathing through the nose only.

Does 220 minus age tell me my real max heart rate?

Not reliably. Galpin describes it as extremely generic, with no fitness meaning in either direction. Heart rate recovery, roughly 30 beats per minute in the first minute after exhaustion, is the more useful metric.

What should my grip strength be?

Men should reach at least 40 kg on a hand dynamometer, ideally above 60; women should clear about 35 kg. Keep the difference between hands under 10%.

How long should I be able to dead hang?

Thirty seconds is the minimum, 30 to 50 seconds is good, and more than 60 seconds satisfies Galpin. The standard bends at bodyweight extremes: 240 pounds is hard to hang regardless of fitness, and 145 pounds hangs easily.

What FFMI do I need for health?

Men should sit at or above 20 and women at or above 18. Below 17 for men and 15 for women is severe physiological detriment. Measure after about 48 hours of rest, since hard training distorts body composition readings.

Which tests can I do on the same day?

Power, maximum strength and muscular endurance pair well in one session, ordered from least to most fatiguing, with the endurance test reusing the strength load at 75%. Anaerobic capacity and VO2 max need their own days, or follow the long-duration test as a warm-up.
