How do you train(workout)?

[ATLSRT8]

Why do you say that's a dumb grouping? Just wandering, not trying to say that's the right/wrong way to do things. I've always hear of back/bi and chest/tri as "push and pull" excersises where you're grouping the muscles together that do similar muscle movements while working out.

And damn I can't focus on diet to save my life. Besides quitting all the soft drinks, im hopeless.

Chest exercises use a lot of tricep, so by the time you are done with your chest your tris are fatigued and they wont get a full proper workout as training with a fresh set of tris. Back/Bi works the exact same way.....when you work back your biceps will feel swole bc they are the secondary muscles used in most back exercises.
