Instructions
Position yourself on a decline bench so that your feet are secured by the pads. Lay back and place your arms across your chest or behind your head.
Begin the movement by pulling yourself up by your abdominals. Do not force yourself up by pulling on your neck. Let your abs do all the work.
Once at the top, slowly lower yourself back down. Again, focus on the abs doing all of the work. Repeat by bringing yourself back up.
