For the past while i've been doing a split workout
and recently i wanted to change things up so i started doing a full body workout for the past month which is doing me really good. To me the full body workout gives you a big pump and lets you work out each muscle group 3 times a week but on a split i fill like i'm concentrating on that one muscle group way more than a full body. What do you guys think of doing a full body workout one week and a split the next and just alternating them every week? I figured if you do this it will keep your muscles guessing and perhaps really, work do you guys think?

It depends on your goals. If you're training for bodybuilding, I would stick to the split routine. But if you're just training for general fitness, alternating your training style from a week to week basis definitely wouldn't hurt.
