Sometimes, going to a personal trainer is the right move – especially when you have specific, goal-oriented needs like losing 20 pounds or achieving a personal record in a 10K. But if you're simply looking for new ways to stay fit, your money may be better spent elsewhere, say, on group classes or, the cheapest and most convenient option, a fitness DVD. To cut through the infomercial hype and find a fitness video that is high quality and actually delivers results, we got our hands on the five most popular videos and took them on a weeks-long, intensive test ride. What we found while sweating in our living room: Not all videos are equal, but that's a good thing, since there's a different workout for everyone.
Premise: This eight-week training program lets you work alongside MMA legend Georges St-Pierre (considered to be one of the fittest fighters in the UFC) through a series of intense cross-training circuits – the same weight training routines that GSP uses to prepare for fights.
Pros: All of the routines are broken up into five, five-minute rounds that, by design, make each workout fly by faster. All of the multi-joint, total body exercises are also effective at not just helping you burn fat, but they build muscular strength and endurance using minimal equipment (either dumbbells or your own bodyweight), making the routines easy to do anywhere with less additional investment.
Problems: The program expects you to exercise six times weekly, which may be too much if you lack enough time.
Perfect for: Men looking to build muscle and burn fat, but desperate for a routine that's more masculine and tough compared to other circuit programs. [$89.97; gsprushfit.com]
