This advice on body alignment and locking in the high position is fully validated by movement science. Biomechanical analyses, notably those detailed by researcher Brad Schoenfeld (literature review), confirm that an aligned body actively engages the abdominals and glutes to stabilize the torso. The work of specialist Stuart McGill (expert opinion and observational studies) further emphasizes that a neutral posture protects the lower back from unnecessary tension during dynamic core exercises. Regarding the high phase, electromyography (EMG) research indicates that full arm extension with active scapular protraction recruits the serratus anterior, a key shoulder stabilizer. Finally, a famous 2019 observational study from Harvard University associated a high capacity to perform push-ups with lasting indicators of physical fitness and cardiac vitality. This challenge is therefore an excellent way to combine strengthening and joint stability in a safe manner.
