Hi Fakii, what i would recommend to him would be heavy weights 4x6 set range and 3day bodypart split, why? this will hold onto muscle and strength best when in a low calorie diet. Its very unlikely you will gain strength when in low calories, so maintaing what you have is normally the best policy.

This will allow you to go into a calorie deficit targetted for weightloss and allow you to hold onto as much muscle as possible as you lose the bodyfat.
