Andy Galpin outlines nine physiological adaptations achievable through exercise: skill and technique, speed, power, strength, muscle hypertrophy, muscular endurance, anaerobic capacity, maximal aerobic capacity, and endurance. Together, these provide a comprehensive framework for assessing and improving physical health and athletic performance.
Galpin emphasizes that proper technique prevents injury and supports long-term training. He recommends a self-assessment by recording yourself performing push-ups, pull-ups, squats, and deadlifts, then evaluating limb symmetry, stability, positioning awareness, and joint range of motion on a 0-1-3 scale.
For strength testing, Galpin suggests multiple methods: hand grip dynamometry (minimum 40kg for males, 35kg for females), dead hang tests (30+ seconds minimum), leg extensions (aim for body weight), and goblet squat holds (half body weight for 45 seconds). Power can be assessed with a broad jump test—you should at least match your height.
Muscle hypertrophy relates to both appearance and health, with the Fat-Free Mass Index (FFMI) serving as a key indicator. Galpin notes that FFMI targets are over 20 for males and over 18 for females. For muscular endurance, he recommends standard bodyweight tests like push-ups (25+ for males, 15+ for females) or resistance-based tests using 75% of your strength maximum for multiple repetitions.
Anaerobic capacity is assessed through 30-60 second maximum efforts, with heart rate recovery being the most relevant measurement—aim for at least 30 beats per minute drop in the first minute. For maximal aerobic capacity, Galpin suggests the Cooper's 12-minute test or Rockport walk test to estimate VO₂ max, with targets of at least 35 for males and 30 for females. General endurance is demonstrated by maintaining continuous activity for 20-30 minutes, ideally using nasal breathing throughout.
Galpin emphasizes that fitness assessment doesn't require expensive equipment or lab access. Video recording provides cost-free movement quality assessment, while a $25 hand grip dynamometer offers objective strength data with population benchmarks. Power can be gauged with just a tape measure for broad jumps, and cardiovascular fitness can be measured using field tests like Cooper's or Rockport protocols with only a stopwatch.
For reliable results, Galpin stresses proper warm-up protocols and waiting at least 48 hours after exercise before body composition testing, as recent activity can temporarily skew results.
Galpin recommends annual fitness assessments to track progress and identify training priorities. He suggests a three-day testing schedule for optimal accuracy and recovery.
Day 1 should begin with non-fatiguing tests like body composition and movement quality assessments, ideally 48 hours after intense training. These are followed by skill, power, and maximum strength tests with five to seven minute recovery periods. Day 2 focuses on fatiguing assessments including muscular endurance and 30-second maximum sprint tests for anaerobic capacity. Day 3 is reserved for aerobic assessments like endurance tests or VO₂ max testing, which can affect performance in other tests if done simultaneously.
Galpin explains that this strategic ordering maintains performance for neuromuscular-dependent tests and ensures accurate data collection. Annual testing guides training prioritization by revealing constraints that limit fitness, allowing individuals to address critical deficiencies while maintaining strengths for balanced fitness improvement.
1-Page Summary
Andy Galpin details the nine physiological adaptations achievable through exercise, encompassing skill and technique, speed, power, strength, muscle hypertrophy, muscular endurance, anaerobic capacity, maximal aerobic capacity, and endurance. These adaptations provide a comprehensive framework for assessing and improving physical health, functional ability, and athletic performance.
Skill or technique development relates to proficiency in specific movements or sports, such as running efficiently or mastering activities like shooting a basketball or swinging a golf club. Galpin emphasizes that strong technique not only boosts performance but also helps prevent injury and supports long-term training. To assess movement quality, he recommends a four-step self-assessment by recording yourself from frontal and side views completing three to ten slow, controlled reps of key exercises: push-ups, pull-ups or rows, squats, and deadlifts.
When reviewing recordings, focus on four factors:
Exercises are scored on a 0-1-3 scale:
Speed measures maximum velocity or acceleration. For most non-athletes, speed testing is not essential. However, athletes may benefit from specialized tests such as the 40-yard dash or velocity transducers. For the general public, direct testing is less relevant, though speed training remains valuable for performance enhancement.
Power, defined as force times velocity, can be assessed with a standing broad jump test—an accessible, equipment-free assessment. Stand behind a line, jump forward maximally with both feet, and measure from the starting line to the farthest back heel. The key goal is to at least match your height: a five-foot-five person should broad jump at least five feet five inches, while elite athletes may achieve nine to eleven feet. For women, reduce expectations by ~15% due to overall differences in power output. If you meet or exceed your height, you have healthy power for daily life.
Strength is the capacity for maximal force generation. Multiple simple assessments are available:
Muscle hypertrophy relates to muscle size, affecting both appearance and health. The Fat-Free Mass Index (FFMI) is a key health indicator:
Muscular endurance—the ability to sustain repeated contractions—varies by muscle group. Two main test types:
The Nine Physiological Adaptations From Exercise
Assessing fitness adaptations does not require expensive equipment, laboratory access, or professional coaching. Reliable, objective insights into movement quality, strength, power, and cardiovascular fitness can be obtained using simple, accessible methods.
Recording exercises from the front and side provides a cost-free way to spot asymmetries, instabilities, and joint range-of-motion (ROM) limits. This allows users to self-assess movement patterns and detect issues that may require attention or specific exercise selection. A standardized framework for evaluating symmetry, stability, proprioception, and joint range of motion gives individuals guidance for monitoring progress and making informed training adjustments without professional oversight.
A $25 hand grip dynamometer offers an objective, validated measure of grip strength, with widely available population benchmarks for comparison. This compact, affordable device enables regular monitoring of adaptation to training. Where purchasing equipment is not feasible, gym machines can serve the same purpose without personal investment, allowing for safe and standardized tests of various muscle groups. Bodyweight movements can be leveraged to assess relative strength for those without commercial gym access.
Power and speed can be gauged with a broad jump test requiring only a tape measure or marked floor. This objective measure of lower-body power is easily repeatable. Many effective bodyweight exercises, such as timed push-ups or squats, require no equipment or digital technology, offering scalable assessment options for all fitness levels. Access to gym equipment further expands these options without the burden of purchasing gear.

Cost-Free and Practical Methods to Assess Fitness Adaptations
Annual fitness assessments are essential for tracking progress, prioritizing training needs, and identifying performance constraints. A strategic approach to scheduling and sequencing assessments ensures accuracy and meaningful results, while balancing recovery and performance.
Andy Galpin recommends conducting non-fatiguing tests, like Fat-Free Mass Index (FFMI), body fat composition, and movement assessments, at the very beginning of a testing session. This should ideally be after a 48-hour rest from intense training. Acute exercise can influence body composition results due to factors like inflammation and water retention, making it critical to avoid strenuous activity the day before and, preferably, 48 hours before testing. This fresh state also applies to movement quality assessments, as muscle soreness or fatigue can hinder accurate evaluation.
After non-fatiguing tests, skill, maximum strength, and power assessments should be scheduled. For example, one-rep max tests or skill-based movement evaluations are best done at the start of the assessment period, when fatigue is minimal. These should precede endurance or high-intensity, fatiguing activities to provide the most precise data.
For optimal accuracy and recovery, Galpin recommends a three-day testing schedule, ideally conducted at times of major training transitions or, at minimum, annually. This approach is similar to an annual physical for overall health.
On Day 1, begin with body composition and movement assessments when the body is freshest. Skill, power, and maximum strength tests, such as a one-rep max leg extension, follow. Recovery periods of five to seven minutes between maximal efforts ensure sufficient recovery. To complement maximum strength measures, subsequent sets at roughly 75% maximum load for maximum repetitions can provide muscular endurance data.
Day 2 focuses on fatiguing assessments: muscular endurance tests and anaerobic power evaluations, such as a 30-second maximum sprint or similar high-intensity tasks. These tests generate significant fatigue and should not precede other assessments that require a fresh state.
Day 3 is reserved for aerobic assessments, such as endurance tests or VO₂ max testing. These are best performed on a separate day as the high demand they place on aerobic capacity can affect performance in other tests if done on the same day.
Correct sequencing is crucial for maintaining performance in tests reliant on neuromuscular function. For example, conducting a ...
