So I just got back into lifting recently. I've been using full body routines 3 times a week, using basic compound movements. For whatever reason i'm not sore the next day after a workout. I've been squating 225 for 4 sets 6-8 reps ass to grass. Should I keep squatting or should I start using the leg press with bigger poudages say 400-500? Its the same with benching.I just don't get why im not sore. Is lack of sorness an indicator that the poundage is too low?
And a last one. I read that you need to be able to run a 5-7 minute mile to get big, because gaining muscle requires a strong heart and a good set of lungs to push yourself hard enough. Are some of you bigger guys able to do this? Thanks.
