would suggest doing either a upper/lower split or full body 2-3x a week, if you are trying to gain strength and/or lose body fat. This will get you there a lot faster than following a traditional bodybuilding split. You have to have really good genetics and pristine diet to make major gains for that....and or drugs. It also depends what muscle groups you are wanting to focus on. Also suggest HIIT no more than 2x a week if you are lifting a lot. Yeah, hiit training sucks.
Right now, I am doing a upper/lower split 3-4 workouts a week. Currently I'm doing a 5x3-5reps for my heavy lifts(deadlift, front squat, etc), then focus more on bodybuilding style(8-12) for back, shoulders, glutes, some chest, and then accessory work. I only do two bicep and tri exercises a week cause it isn't my focus. For cardio, I swim and bike. However, I should be cleaning up my food and doing hiit. Again, it depends on what your goals are.
Anyone here done 5x5, 5/3/1, or a Candito powerlifting program?
