If you get 100 reps for the whole workout, then move up to the next level when we repeat this workout in 2 weeks
Go HEAVY and LESS reps if you want, nothing is wrong with going really heavy here for sets of 1-3 reps each set
After you are done - practice going up to as heavy as possible on kettlebell levers and/or kettlebell sit ups (with a partner holding your feet) for 5 sets
