What should I fix in my routine/diet?

[moneyistheanthem]

Starting to get back to the gym and need to know if my old routine is good for building muscle or not. Friend says I should be doing more sets with higher reps (3 x 8-12). Currently in a recomp because I'm built like the beast titan (6'2 215lbs)

. I take 2 rest days after each workout. Aiming for 3,000 cal a day with 220g of protein. I don't count macros (should I?) I also try getting at least a gallon of water and 10,000 steps a day. Diet consists of mainly steak or chicken with either rice or beans and vegetables.

Here is my old/current routine
