What are the biomanical principles of doing a pushup?

The biomechanical principles of doing a push-up involve proper alignment, force generation, and joint mechanics. When performing a push-up, the body should form a straight line from head to heels, engaging the core to stabilize the spine. The movement primarily utilizes the pectoral muscles, triceps, and deltoids, while the wrists and shoulders must maintain a neutral position to prevent injury. Additionally, efficient force transfer through the upper body and legs enables effective lifting and lowering of the body.
