7 LITTLE-KNOWN HACKS FOR BIGGER ARMS

 3 of 6 Volume has been shown to have direct correlation with muscle growth. 

3 of 8  INCREASE YOUR VOLUME

This means if you're doing eight sets of arms once per week and are getting no results, you need to up your volume. I recommend adding additional sets on another day a week for arms.

Do not just jump into three days per week without slowly increasing your volume otherwise you risk injury.
