For almost half a year i have been doing back and bi's together and chest and tri's together.
Day 1: Chest/delts/tris
day 2: legs
day 3: cardio
day 4: back/bi's/traps
day 5-7: off

i was thinking of changing to this to shock my body
day 1 bi's/tri's
day 2 legs
day 3 off
day 4 back
day 5 chest/delts.
day 6 off
day 7 off

how would this split work n yalls opinion?
