Nexersys Boxing Trainer

You could hone your boxing skills on a heavy bag… or you could give Nexersys Home a shot. This rather large steel device puts seven vinyl strike pads at three different height zones, measuring and displaying accuracy, impact force, reaction time, strike counts, heart rate and caloric burn on its 19-inch LCD display as it trains you – and up to four other distinct users (not all at once, mind you). Otherwise, opt for the red Pro version, which swaps in leather strike pads, a heavier-duty (and just plain heavier) frame, 22-inch touch screen display and a significantly larger price tag.
