The aim is to achieve 100 reps per day from a choice of four exercises. You could do star jumps, squats, sit-ups or a plank, choosing to complete a combination of all four, combine a few or just choose one – the only criteria is you must equal 100 reps per day. As an example you could complete 50 squats and 50 star jumps to equal 100 reps or 40 sit-ups and a 60 second plank to equal 100 – the choice is yours. Take part on your own, with friends, at home or in the gym. It’s your challenge, your way

If you donate let me know and you can choose one of the exercises that I include
