I am totally confused! Tonight I was working on one of my workouts (shoulder and traps) and a personal trainer who I always see at the gym asked me for a spot, and I started talking with him/asking questions. He told me you should work opposite muscles on the same day, aka bi’s and tri’s.
I, for the past 4 weeks, have been doing as follows, chest/tris, back/bi’s, legs, shoulders/traps.
Now, if I were to work opposites, what would it look like if i wanna hit each muscle twice a week? Thanks guys, I am just confused because there are a lot of opinions out there about same muscle groups etc.
