There's nothing like a good infomercial to grab your attention! "Get ready to punch your way to the perfect body." Consumer Reports tested three - Jay Glazer's Perfect Punch … Rhythm Rocker by Kymaro … and for women - the CoreBody Reformer. "We rounded up staffers to try out each product. We called on a fitness industry expert to evaluate each one. We even had our nutrition expert take a look at the diets that came with two of the products." "Just glove up, strap in, and start punching!" The 30-dollar Perfect Punch uses mixed martial arts techniques to get you in shape. But Consumer Reports found you can burn roughly the same amount of calories jogging four-and-a-half miles per hour for 16 minutes. And it was far from perfect. Eugene Chin "It kept rubbing against my shoulder." Erin Gudeux "One more time those bands come snapping up and hit me in the ears, I was going to rip it in half." Next up - the 99-dollar Rhythm Rocker by Kymaro. "The rockin, crunchin', rollin' workout system." The Rhythm Rocker comes with several different workouts and a nutrition guide. Consumer Reports' panelists tried out the eleven-and-a-half-minute dance blast video. Turns out you burn the equivalent of walking only two miles per hour on a treadmill. Kim Kleman "As for the seven-day diet, it's pretty strict so you could probably lose weight, but our nutrition expert said it offered limited food options and no maintenance program." And finally the 250-dollar Nautilus CoreBody Reformer for women. It combines yoga, Pilates, and dance in one workout. Panelists found some of the balance exercises tricky, but overall this machine did well in Consumer Reports tests. Kim Kleman "The workouts are well-rounded, and if you're somewhat fit and are looking to improve your strength and flexibility, it might be one to consider." ."
