Targets: Chest and core
This exercise builds on an old staple — the push-up — to provide an extra element of
shoulder stability alongside some core training. Since the TRX straps move independently of one another, they force lifters to stabilize their arms using often-neglected muscles in their shoulders. The result: better shoulder stability and a tighter core in one exercise.
How to: Start with a handle in each hand facing away from the pivot point. Move your feet back so that you’re in push-up position with your hands directly underneath your shoulders. Keep your midsection pulled in tight as you slowly lower yourself into a push-up. Press yourself back to the starting position. Then, keeping your arms as straight as possible, reach straight overhead to elongate your body and force more of the work on your core. Pull your hands back to push-up position and repeat.
