Do Those Exercises Correctly!

In 4 Exercises You're Doing Wrong At The Gym, Philadelphia trainer Brian Maher explains the proper technique for four common exercises.

1. In the lunge, keep your step long enough to avoid having your knee go over your toes and don't lean forward.
2. Align your hands with your shoulders and keep them even with your chest when doing push-ups.  Keep your body straight from your head to your knees to keep your hips from sagging.
3. Keep your eyes on a spot directly above you while doing crunches and contract your abs to lift your back and shoulders off the ground.  This reduces the chance of straining you neck.
4. Half of the benefit of bench pressing is lowering the weight back down so don't use so much weight that you slam the weight down against your chest instead of bringing it down slowly.
