5x3x1

Hello all, I just wanted to take a quick moment to introduce myself. Im 46 and returned to the gym about a year ago, after a 3 year stent away. my life consist of a wife of 15 years and 2 boys 10 and 4. Yes I know im 46 and have a 4 year old, happy wife happy life right. I am a student...

I really dont want to have to buy a copy of beyond 5x3x1. I have the original 5x3x1. He talks about Jocker sets and Down sets. Have been reading some stuff but not real sure on it. sounds like Joker sets are only used if you feel in the heavy mode. Any info you folks have would be great. Thanks
