The TRX Single Leg Chest Press uses a more demanding leg position bringing the standing leg forward rather than out to the side. The TRX Side Plank adds a pike to each swing by bringing the hips up as high as possible on each side. The Suspended Crunch element of the TRX Atomic Push-Up is replaced with a more advanced pike movement. The TRX Suspended Oblique Pike is combined with the Body Saw. Rock your body back and during the forward motion pike your hips up as high as possible to one side, keeping your legs straight.
For the Single Arm Power Pull really reach up as far as you can up the strap as you pull yourself towards the anchor point. To make this more difficult, have a partner mimic giving you a "high-5" at the top of the strap as a target to reach. Once you make contact, have them apply some pressure to your hand, pushing you downwards as you try to resist.
