The habit: Wincing, squinting, groaning and straining your facial muscles while lifting weights.

Why it's making you look older: You know that squinting can cause wrinkles, and that's why you invested in those broad-spectrum UV sunglasses. But bright sunlight isn't the only thing that makes you squint. Bowe says straining your facial muscles while doing exercise can have the same affect.

The fix: Do a few reps in front of a mirror to see if you're practicing incorrect "face form." If you are, try to focus on your breathing during reps: It's hard to scrunch up your face while inhaling and exhaling.
