Work out smarter with this shirt.

Are you sitting up straight for this?

Probably not.

If you're like us, you're likely slumped over your computer right now. But poor posture not only makes you look dumpy--it can also make your workouts less effective and increase your risk of injury.

IntelliSkin, a new clothing line designed by sports physician Dr. Tim Brown, claims to instantly help you stand taller, look leaner and feel stronger. Here's how it works: The snug-fitting shirt has panels (similar to compression wear) that open and stretch chest muscles. Vertical panels keep the spine long and upright. Surfer Kelly Slater, LA Laker Derek Fisher, celeb trainer Andrea Orbeck and some surprising famous names say it helps them perform better and reduces their injury risk.

We tried it on and immediately noticed that our shoulders shifted down and our posture was straighter. Then, we did our usual resistance workout. Our arms felt the burn faster because we couldn't be sloppy with our form. It's not cheap, but we think the investment is worth it.
