Wall Sit hip and knee angle, held as fatigue builds
What Systematic recommends
Where to start
- Stand facing the counter or other stable surface and step back until your body is positioned at approximately a 45-degree angle, place your feet roughly shoulder-width apart and keep your heels flat on the ground.
- Place your palms on the counter, keep the elbows still throughout the movement, engage your midline as if holding a strong plank position and keep the midline stable and the abdominal muscles active.
- Hold the position for 15 seconds. Rest for 15 seconds. Repeat for 3 total cycles. Press the palms firmly into the counter as if trying to push it away. Breathe comfortably and fully throughout the hold.

What muscular endurance means
Endurance is the ability to keep working while fatigue builds. The Wall Sit makes that visible as a single hold: a timed test of how long the front-of-thigh muscles can hold a fixed 90° hip and knee position. Unlike a moving repetition, the muscle stays contracted the whole time, so the test is about holding force and coping with local fatigue.
Push-ups are different because your body moves. In a push-up the arms carry a substantial portion of body weight, and the trunk has to stay stiff so the body moves as one piece. Repeating that at a controlled pace adds fatigue to the coordination job. That is why Systematic treats the tempo push-up as a whole-body endurance task scaled to your own weight rather than an arm test.
The Dead Hang measures grip endurance and how well the upper body stays coordinated as it tires while you hang from a bar. It draws on the fatigue resistance of the forearm and finger muscles.
How the tests are kept fair
Each test fixes the position, so fatigue is what gets measured. In Tempo Push-Ups, sagging hips or arching the lower back to finish a repetition is not allowed. Research by Howarth and colleagues on the abdominal muscles during push-ups supports the trunk-stiffness demand, though it did not use the Systematic tempo.
Pace changes the result. In a study by Rozenek and colleagues, cadence materially affected push-up performance, which supports using one set pace and reading men's and women's results separately. Time to failure should not be assumed to change in a straight line with pace, so results at one pace cannot simply be converted to another.
A study by Adams and colleagues supports testing women in the standard floor push-up rather than switching them to the knee version. It studied college-aged women doing self-paced push-ups, so its numbers are not adult norms for the Systematic test or its 3/0/1 tempo.
What research links to health
One study, by Yang and colleagues in 2019, looked at ordinary push-up capacity and later cardiovascular events in active adult male firefighters. It does not mean a Systematic Tempo Push-Up score can predict a person's own cardiovascular risk.
More broadly, the authors of a study of older adults point out that doctors' risk assessments rely largely on existing illnesses and often overlook what a person can physically do.
In this capacity
- What did Yang et al. (2019) find? Association Between Push-up Exercise Capacity and Future Cardiovascular Events Among Active Adult Men
- How much of your body weight do you lift in a push-up?
- Is muscular endurance linked to mortality?
- Does push-up capacity predict heart disease?
- How are push-up standards set for women?
- What does a push-up ask of the trunk and shoulder blades?
- Why are push-ups tested to a set tempo?
The evidence
Each cited source is labeled according to how it supports the particular claim on this page. Direct test evidence, underlying-capacity findings and population reference values are distinguished from Systematic-defined protocols and standards. Historical development notes are retained internally rather than presented as public evidence. A study of an underlying capacity is never presented as validation of the Systematic test itself.

Underlying-capacity evidence
Yang et al. (2019). Association Between Push-up Exercise Capacity and Future Cardiovascular Events Among Active Adult Men. JAMA Network Open.
What it found. Studied ordinary push-up capacity and later cardiovascular events in active adult male firefighters.
What it does not show. It did not use the Systematic tempo, and it does not show that a Tempo Push-Up score predicts an individual's cardiovascular risk.

Underlying-capacity evidence
Dhahbi et al. (2022; published online 2018). Kinetic analysis of push-up exercises: a systematic review with practical recommendations. Sports Biomechanics.
What it found. In a push-up, the arms carry a substantial portion of body weight while the trunk stays stiff.
What it does not show. It does not give one fixed percentage of body weight for every person, and it is not a study of the Systematic test.

Underlying-capacity evidence
Howarth et al. (2008). Abdominal Muscles Dominate Contributions to Vertebral Joint Stiffness during the Push-up. Journal of Applied Biomechanics.
What it found. The abdominal muscles were the main contributors to trunk stiffness during the push-up.
What it does not show. It did not use the Systematic tempo protocol.
-
Underlying-capacity evidence
Rozenek et al. (2022; published online 2021). Male-Female Differences in Push-up Test Performance at Various Cadences. Journal of Strength & Conditioning Research.
What it found. Cadence materially affected push-up performance, supporting one standard pace and separate interpretation for men and women.
What it does not show. It does not show that time to failure changes in a straight line with pace.

Underlying-capacity evidence
Suprak et al. (2011). The Effect of Position on the Percentage of Body Mass Supported During Traditional and Modified Push-up Variants. Journal of Strength and Conditioning Research.
What it found. The standard push-up position puts a meaningful fraction of body mass through the arms.
What it does not show. It measured how much body mass the arms support in different push-up positions, not the Systematic tempo push-up.
-
Normative/reference evidence
Adams et al. (2022). Development of a Standard Push-up Scale for College-Aged Females. International journal of exercise science.
What it found. Supports testing women in the standard floor push-up rather than automatically switching to the knee version.
What it does not show. It studied college-aged women doing self-paced repetitions, so it is not an adult norm for the Systematic test or its 3/0/1 tempo.

Wu et al. (2026). Physical Fitness and All-Cause Mortality in Older Adults. JAMA network open.
What it found. The authors note that risk assessment in older adults relies largely on existing illnesses and often overlooks functional capacity.
What it does not show. Its fitness tests are not the Systematic battery, and it is not evidence about any one Systematic test.
The Systematic Healthspan Assessment is a physical baseline. It is not a diagnosis, and it does not estimate a biological age, a disease risk or a lifespan.
