so trying to figure out what my routine is gonna look like for this summer. I'm thinking I can probably get in 3-4 days a week, depending on my schedule. If i was going four days on week, would a split like this work?

full body
rest
full body
rest
upper
lower
rest

just wondering if its okay to do a upper/lower split while still doing full body workouts in a routine

Yea, that can work.

Just a question. Why not do one more FBW on the 5th day instead of doing back-to-back upper and lower?

nice! i think a split like this works for me then. thanks

oh, and the only reason i wouldnt just do another FBW on the 5th day is that could get to be monotonous for me. this lets me switche it up a little more while still working all the muscles
