I'm practically doing the clapping push ups, 3 sets of 10 reps but towards the end of each set rep getting a little fatigued but still managing to do a the full rep of clapping, and springing myself up etc.... I have made a way that its more different by resting my legs/feet on a higher object, therefore more pressure and thrust is needed, but i'am only doin 5 sets of 5 reps to keep my form to a strong explosive motion etc
