You'll find a second set added to all exercises except the TRX Elevated Back Row and the big daddy--the TRX Suspended Incline Press. These two get a bump up in time/reps for a gut check. Just like Strength Workout 1 for "Week 5," you are performing at a higher volume as compared to last week. If you're not sweating and breathing harder – you’re not trying. You'll find a progression in the TRX Single Leg Chest Press (moving the lifter leg out to the side (abducted)) which will increase demands on your core. Don't let your body rotate! The TRX Oblique Crunch is old news-try the TRX Suspended Oblique Pike (shown above). Don't bend your knees as you drive your hips up, drawing legs towards each arm. You're going to feel core firing and shoulders stabilizing.
