You want to weld your body into a more solid shape, but you're not interested in pumping iron. Cast a finer figure with today's deal from Power Fit Studios at the Opera Tower on Biscayne Bay: Pay $45 for five Power Plate sessions designed to help stimulate weight loss (a $150 value). Using innovative vibration technology, the Power Plate system aims to mimic the effects of a high-intensity workout. Your joints and ligaments won't feel the strain of traditional lifting or pounding, yet you could potentially utilize more than twice the muscle fibers you would with traditional exercise. Generating up to 30 to 50 natural stretch reflexes per second, the Power Plate could stimulate targeted muscle groups, including spinal and pelvic basin muscles that are typically difficult to train. Set up a series of these 20-minute sessions with a personal trainer, and get a physique that's worth setting in stone.
