This is the low-impact mechanical exerciser that gently and thoroughly concentrates on developing strength in the glutes, upper thigh, abdominal, and lower back muscles, and is especially beneficial for novice exercisers or those unable to tolerate excessive pressure and stress on joints. It allows you to conduct a 20-minute exercise routine while seated, making it easy to perform at home while working on other tasks or watching television. The saddle supports up to 265 lbs., gently tilting back and forth, left and right in preprogrammed sequences that can be selected at the touch of a button. The gentle swaying of the saddle forces the core body muscles to expand and contract, keeping you upright in a relaxed, properly aligned sitting position which helps develop important muscle structure necessary to maintain good posture. The exercise routines also provide a beneficial aerobic workout ideal for those who need to maintain low target heart rates. Any of three basic programs and nine speeds are easily controlled from the panel at the pommel, and a set of stirrups and a handle help beginners maintain proper balance during the slow workout that simulates the gentle back-and-forth motion experienced while riding a horse at a lazy gait. Plugs into AC. 29" H x 16 1/2" W x 34 1/3" D. (82 lbs.)
