if he does that, when does he plan on getting back to the weight he used to be doing? I know i am not as experienced as you are, just wondering. Also, wouldn't it be basically pointless to be doing bench around 125, if that in his case? I just don't see the use in deloading so drastically- your CNS will get a break anyway if you deload 10-20% instead of 50%
Also, if you feel your CNS needs a break taking a week off is often advisable.
no he doesnt mean drop down to half then work back up the following weeks. Just one week you do half the volume you would normally, so you still do sets but no real hard sets just enough to get the blood flowing, then the week after u continue where you left off.
Deload is the name given for a workout like that, it gives your body and mind a break from the intense lifting but still allows you to get in the gym and gets the blood flowing which is good for recovery
