Feet-elevated Push-up (on Stability Ball)

Get into a push-up position with your hands on the floor, slightly wider than shoulder-width apart.

Rest the tops of your feet or shins on top of a stability ball behind you, legs extended.

Engage your core to keep the ball stable and your body in a straight line from head to heels.

Lower your chest towards the floor by bending your elbows, keeping the ball steady beneath your feet.

Pause for a moment at the bottom, then push through your palms to return to the starting position.

Repeat for the desired number of repetitions.

Losing tension in the core or lower back partway through the movement — because Feet-elevated Push-up (on Stability Ball) loads multiple joints at once, a small breakdown in bracing at the hips or spine compounds through the whole chain.

Locking out too fast or letting the elbows drift outward under load — controlling the eccentric (lowering) phase is where most of the muscle-building stimulus happens.

Skipping a warm-up set at lighter load/intensity — even "beginner" exercises benefit from a rehearsal set to groove the movement pattern before working sets.
