I also work out legs, glutes, pecs, and back but on different days
So how many hours should I work out each on different days ?
Once a week per muscle group. ;D Works like a charm. Six hours a week is the max time you should be in the gym. For just weight lifting. I recommend two muscle groups per day that relatively work with another muscle such as working out your chest and your triceps. Biceps and back. Calfs and lower back. Etc. I hope you get me. Whats your diet like? Let me know. (firstname.lastname@example.org)
