For this move each participant should choose an appropriate style according to strength ability (e.g., on the toes or on the knees) and you can do the move completely on the rebounder (beginners box push up) or with feet on floor and hands on the rebounder rim or mat or with feet on the rebounder and hands on the floor (as in a decline push up) depending on level of intensity.
Place hands just outside shoulder width so your little finger is on the mat webbing draw belly button in towards spine and maintain neutral position.
In this move watch out for forward head posture i.e., extension of cervical spine and dropping the head down. Also watch for winging of the scapula and increased lumbar extension.
Pay attention to alignment for good form.
