“I’ve been using The X-iser® Machine for the past five years at my office and it has become a regular part of the physical training programs I design.  My clients of all ages routinely begin and finish their work sessions with the short “triple blast” program.  Most people find it quick and easy but very challenging and effective.  And, at a fraction of the cost and size of the big treadmills and stationary bikes, many choose to buy their own X-iser® Machine for home use. “
