Gymboss Interval Timer
Everyone wants to spend less time working out with the same results, right? The Gymboss Interval Timer [$20] you get precise interval training, a mix of high and low intensity cardio. Researchers at the University of New South Wales in Australia conducted a study in 2009 with two groups – one exercised on a stationary bike for 40 consecutive minutes and the second biked for 20 minutes, alternating intervals of sprints and slow peddling. In the end, the interval training group lost three times more body fat in half the time!
