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. |
