This question kind of seems like the "am I working out too hard?" question, but it's a bit different.
This question asks about whether or not one should trust their body or a timeframe.
I worked my forearms very hard yesterday, but today I did a lot of cardio and got a lot of blood pumping, plus high carb and protein loading -- and I feel completely replenished. I feel as though I should maybe workout again today. I used to go by timeframes before and never listened to my body because people always told me "rest 3-5 days between every used muscle group." I highly doubt I ever overtrain since I always see progress, however small, even if I workout two days in a row. I also use tons of supplements, so I never feel any muscle pain/fatigue/DOMS/etc. no matter how hard I go.
And I go REALLY hard -- no kidding. I can do over 50 sets in 30-45 minutes with little breaks at 50%.
I have never had any injuries and I rarely get DOMS -- usually only in the calves, but don't know why since I'm a 5 year runner and have pushed my calves beyond what most would dare to.
I, instead of feeling pain afterwards (like the next day), usually just feel tightness for a few hours right after highly intense workouts -- and within 48 hours I almost always feel like I go very hard again.
Maybe my body is recovering fast enough, and it's just really hard to overtrain? I don't want to lose any greater results I could theoretically obtain from training more. So should I just listen to my body?
I think it seems to make more sense to workout 1-2 days in a row, and then rest for a few days, also throwing in some light exercises in between. I have more concern under training than over anyways.
So what are some thoughts on this? Go the extra mile or don't be fooled by the green light?
