For the last 6 months I have been doing a 3 day routine twice per week in the following structure:
- Legs and shoulders
- Chest and triceps
- Back and biceps
I have seen very good results with this routine (I'm fairly certain it is quite a common plan) but lately I haven been reading a lot about doing chest and back on the same day.
I'm considering changing my routine to:
- Legs and shoulders
- Chest and back
- Biceps and triceps
But I am very skeptical of having two large muscle groups (chest and back) on the same day. I have always been under the impression that recovery doesn't yield good results if you hit multiple large areas. I did previously train biceps and triceps on the same day with better results than I am currently experiencing, but my current routine overall is working better.
Would this change have better results than my current routine? What are some pros and cons of what I am doing now vs the proposed routine? I've touched on some material talking about lactic acid moving around in a beneficial way during your workout if you alternate chest and back sets, but I'm not sure what is true and what's not.
My goal is mass.
