Im following 531 and I was wondering if it was okay if I did my 531 sets and did Joker sets after, then finished with 5x10 at 50% for BBB work. I have tried it a couple times now and I enjoyed it.
From Jim's web site:
But, at the end of the day, do what you think is best for you.
Your question has been answered a lot of time, btw.
If based on your years of experience this has proven to work, I think you should follow your own experiences. There is much strength in decades of experience.
