Push-ups with feet on the ball

Lie on the floor face down, palms 90 cm apart. Put your feet on the fitball. On an inhale, lower yourself until your chest almost touches the floor. Tightening your chest muscles, as you exhale, return to the starting position. After a second pause, repeat the movement and complete the required number of repetitions. Variations: Instead of a fitball, you can use a bench.
