Reps for Alternating Arms/Legs

Mike, I was wondering in your workout routines when there are sets that dictate, for example, 15 reps alternating arms, is that 15 reps total or 15 on each arm for a total of 30 reps? Thanks so much!! Big fan of your 101 vids. They help a lot!


Thanks and so sorry for the delay. I have been bogged down. That means 15 per side. Yea not easy I know. LOL
