I work biceps and back on wednesday and they're never sore the next day, eventhough on every other workout (chest + shoulders, tris + legs) they throb the next day.
This is my routine. Short, yes I know:
10reps x 4sets - Bent Over Rows
60% (of max) x 3 sets - Chin Ups
10reps x 4sets - EZ Bar Curls
12reps x 3sets - Dead Lift
I guess maybe it's too short? I'm probably going to get slated for doing 12reps on deadlift but I read higher rep range (if you're interested in building muscle not strength) is great for full-body gains.
So why am I not sore the next day and what can I do to chance it?
