Time to double it up in the Military Fitness Program's "Week 5". All exercises are bumped up to two sets this week, but the reps are reduced. The rest between sets and transition time between exercises is fixed at 45 seconds. The TRX Body Saw (above) is an exercise progression of the TRX Suspended Crunch. This means you are doing significantly more total body work so be ready! By now you should be well on your way to mastering the exercises. The next step is to increase volume so you can take your fitness to the next level. The rep level is set at ten. If you are find that 10 reps is a relatively easy volume, change your body position or perform the moves at faster tempo. Form is always your guide-move better before moving faster.
