I've been wondering this and nobody has been able to give me a definitive answer. Currently I'm doing three sessions a week, they average from 40 to 60 minutes each. I was thinking of breaking this into five sessions a week, same basic exercises, reps, etc., just shorter sessions (mainly to fit them into my day better) spread across more days.
On the surface it seems like it should be the same level of effectiveness, am I correct?
