Is there any consensus on the maximum number of reps you should perform, before rotating?
Curious as I find I get bored, or start to get say carpet burn (sit-ups), if the number exceeds a hundred. Personally I choose not to do more than 60 of anything, also find 60 a useful number for timing. Then again, back in my student days, I've had house mates who'd happily do 500 push-ups, immediately rotate into 1,000 sit-ups, then on to many squats, as a warm up, before throwing up last night bottle of Vodka over the nearest parked car (learnt were not to park), so I guess it's entirely personal/subjective, but is there any general advice?
