Well I mean since all these neural charge videos and information has been around, my performance in the gym and my energy levels have increased. Beginning of last year I never squatted heavy or deadlifted at all because of a disc in my back and after all the rehab and lay off Im squatting 3 times a week (HPM Program) and training everyday 7 x a week.
I think that active recovery has been the key to my growth lately. I mean Olympic lifters train something like 3 x a day!!!
Through my own experiance and info I have been seeing lately I believe that being "active" on an "off" day pumps the BLOOD throughout your body faster, delivering nutrients and so forth and actually decreasing soreness in my muscles.
I guess it comes down to personal preference but I highly recommend active recovery days.
