I always go back to HIT for a few weeks because I enjoy it more than any other style of training more than any other reason.
With that said and with no bias, I personally think you’d be better off with a higher volume approach.
HIT centers around anti-overtraining IMO. It rails against the split routines that so many bodybuilders “waste thier time with” which I think is BS.
Put that Test to work with a 3 day split rountine over 4 days. Something like the the old tried and true Legs, Back/Biceps, Chest/Shoulders/Triceps, repeat day one on 4th day or something similar.
Maybe 2 exercises per bodypart, 3-4 sets of 6-10 reps. It may be “unscientific” but it will do more while on the juice than HIT.
Oh, and eat like you’re forever starving. This is no time to half-ass the calorie consumption!
(All just my opinion… some may differ).
