Lie on floor with knees on padded surface. Position hands on floor shoulder width or slightly wider. Assume a kneeling plank position, by pushing body up so arms are extended.
Bend arm and lower chest to floor. Immediately reverse direction by throwing body upward by quickly extending arm so hands leaves floor. Catch body and land with hands on floor in original starting position. Repeat.
Keep knees on padded surface. Also keep hips straight throughout movement; upper thighs should be kept inline with torso. Exercise can be performed with feet against floor board.
Begin with conditioning period of easier exercises.
Once this movement is mastered, try more challenging plyo push-up variations.
