i train naturall at the moment doing a 5 day split.
i have a week off training every 6 weeks for body shock.
is it a good idea to always mix reps ??
e.g for 6 weeks go for 12-15 reps and then have a week off and then change it to 4-8 reps for 6 weeks then have a week of and then go back to 12-15 reps etc etc ??
