Target | Lower Abs
With an overhand grip on a pullup bar, hang at arm's length, bending your knees 90 degrees and locking them in this position.
without swinging your body, contract your abs to bring your knees as high as you can into your chest and lower under control, coming to a stop at the bottom so you don't generate momenutm before the next rep. Note:
If you can easily hit the target rep, straighten your legs to make the move harder.
