These high quality abdominal slings from KEYS fitness will take your ab-workout to the next level. Similar to a vertical knee raise machine, yet at a fraction of the cost, you simply suspend your body and perform knee raises to isolate those hard-to-train stomach muscles. Unlike other ab-trainers, SuperAbs allow side to side motion to enhance training of the olbliques. The 7" model also has a leather support pad for added comfort.
4" SuperAb $39.95 (+ $5.40 S&H)
7" SuperAb $69.95 (+ $6.50 S&H)
