Joe Defranco removes Pec Flyes from his "banned list" and shows you the proper way to perform them for some serious growth!

Cues given within video: 

1. Elbows should be 99% locked.

2. Start with thumbs facing each other.

3. Half way down, externally rotate.

4. Pause for a second in the stretched position.

5.  Half way up, internally rotate to get peak contraction.
