The Framework of Physical Fitness
THE FRAMEWORK
Dr. Andy Galpin categorizes the physiological adaptations of physical training into nine distinct areas: skill and technique, speed, power, strength, muscle hypertrophy, muscular endurance, anaerobic capacity, maximum aerobic capacity, and long-duration endurance. Recognizing these separate buckets allows individuals to identify specific performance constraints and target their training more effectively.
Assessing Movement and Power
THE FRAMEWORK
A Four-Step Self-Assessment for Movement Skill
To assess movement technique without professional equipment, individuals can record multi-joint exercises—such as push-ups, pull-ups, squats, and deadlifts—from frontal and side angles. Evaluations should focus on four key markers: symmetry across limbs, stability without shaking, movement awareness, and the ability to achieve a full range of motion. Ensure technical comfort before attempting representative movements to avoid acute injury.
THE EXAMPLE
Assessing Explosive Power with the Broad Jump
Explosive power can be measured simply by performing a standing broad jump without a running approach, measuring the distance from the starting line to the rearmost heel upon landing. A healthy general benchmark is jumping a distance equal to your own body height, with a modest 15% reduction for female benchmarks.
Evaluating Strength and Muscle Mass
THE NUMBER
Grip Strength as a Core Fitness Standard
Grip strength serves as a vital proxy for overall physical strength and can be measured using an affordable hand dynamometer or a simple dead hang from a pull-up bar. Healthy adult male minimums start around 40 kilograms of grip force or a 30-second dead hang, while females maintain slightly lower baseline targets.
Estimating One-Rep Max via Repetition Equations
Rather than testing true one-rep maximums to failure, individuals can lift a heavy load for fewer than five repetitions and input the data into standard online repetition conversion equations. This allows for accurate estimation of maximum strength while significantly lowering the risk of acute lifting injuries.
THE NUMBER
Evaluating Muscle Mass via Fat-Free Mass Index
Fat-free mass index derived from body composition scans like DEXA provides an objective target for muscle mass sufficiency, independent of aesthetic preferences. Minimum health thresholds are established at an FFMI of 20 for men and 18 for women, provided body fat percentages remain within safe ranges.
Measuring Cardiovascular and Aerobic Capacity
Heart Rate Recovery Measures Anaerobic Capacity
While direct anaerobic capacity testing requires intense laboratory protocols like a Wingate test, heart rate recovery following maximal exertion provides a reliable alternative. A healthy cardiovascular recovery drops roughly 30 beats per minute within the first 60 seconds after reaching exhaustion.
THE NUMBER
Estimating VO2 Max via Field Tests
Maximal aerobic capacity can be assessed directly in a laboratory or estimated through field tests like the 12-minute Cooper run test or a submaximal Rockport walking test. Minimum health targets for VO2 max are established at 35 milliliters per kilogram per minute for men and 30 for women, with optimal longevity goals extending much higher.
Scheduling the Annual Fitness Battery
THE FRAMEWORK
Dr. Galpin recommends performing the complete nine-part fitness assessment battery once a year across a dedicated three-day testing split. Non-fatiguing body composition and movement tests should be performed when fresh, while high-fatigue anaerobic and aerobic tests should be placed at the end of sessions or on separate days.
