As an antidote to the negative effects of sitting all day, trainers often recommend adding the glute bridge to your workout routine. And while that’s a good idea, David Jack, one of the co-creators of Men's Health newest fitness DVD Body Battle, suggests upgrading the movement for even better results.

"Long hours spent parked on your rear can cause your glutes to forget how to fire," says Jack. "The glute bridge turns these powerful muscles back 'on,' making you stronger in every lower-body exercise."

But here's how you can make it better: While you're performing the bridge, reach for targets above, below, and to the side of you. This will stretch your chest and enhance your upper back mobility, improving your posture, says Jack.

It also causes your body to be less stable, forcing your glutes and core muscles to work harder with each rep. The benefit: a stronger, leaner body.
