When you're working out at the gym, you'll likely see people do these five exercises all the time. And while those dudes are usually breaking a sweat, thinking that they're doing things right, in reality, they're really just messing up their bodies.

Here are some examples:

DO NOT do tricep dips with your hands behind you on the bench.
INSTEAD do close-grip pushups, parallel bar dips, or lying dumbbell tricep extensions.

DO NOT do any type of jump training on a concrete surface. There's a reason NBA players don't play games on concrete and why weekend warriors are always hurting themselves playing pick-up ball on asphalt—it's not great for you.
INSTEAD absorb the force by bending your knees and pushing your hips back, and by performing jumping moves on softer surfaces.

DO NOT do situps or standard crunches.
INSTEAD do planks, side planks, TRX fall-outs, and jack-knifes. They're much better for your abs and you get more bang for your buck.
