The muscular endurance challenge continues in Strength Workout 2 as nearly all rep volumes increase again and rest times between sets decrease. You are still only doing two sets of each exercise, but your muscles will really feel it on round two with those extra reps. Perform the reps for the TRX Suspended Incline Press a little faster this time around. You have 30 seconds less to kick out those twenty reps.
For the TRX High Back Extension (pictured above) start with your hands overhead, making sure you have full tension on the TRX before you allow your tailbone to drop back towards the floor. If it's more comfortable, you can keep your toes planted on the floor. This won't take away from the power of the movement.
