This is the low-impact mechanical exerciser that methodically tilts across five axes to strengthen your core muscles, helping improve your balance and posture and relieve back pain. The saddle tilts back and forth, left to right, up and down, and twists in preprogrammed sequences, strengthening your thighs, buttocks, back, and deep abdomen--core muscles that are neglected by traditional training regimens. The gentle swaying of the saddle changes your center of balance and, as you attempt to regain your equilibrium, your core muscles expand and contract. Ideal for both physically limited and experienced exercisers, the device allows you to conduct a 15-minute exercise routine while seated without creating excessive pressure and stress on joints. The exercise routines also provide a beneficial aerobic workout ideal for those who need to maintain low target heart rates. The seven programs (easy, light, moderate, advanced, waist, hip, legs) and nine speeds are easily controlled on the pommel's LCD panel that also shows calories burned and the muscles being worked during each routine. With a set of stirrups and handle to provide stability. 29" H x 18" W x 35" D. (77 lbs.)
