Begin balancing in plank position, shoulders stacked over your wrists, legs shoulder-width apart.
Lower your body toward the floor and then push through your arms, returning to plank.
Kneel on the floor with both knees and raise arms overhead for one shoulder press rep.
Return to push-up position and repeat, this time performing two push-ups and completing two shoulder-press reps. (Add on another push-up and press rep each time.)
