I want to get my brother start 5/3/1. He is 16 years old, has been lifting on and off for a couple months, and is familiar with the movements. I know that conditioning & mobility are very important especially for his age, and I will get him bounding (I am also very young and you once said I should be bounding) and doing Agile 8 every day.
But aside from that, which program would you recommend? The 5/3/1 for Beginners that you outlined in your website, or 5's Pro with Jokers as recommended in the Beyond? If 5's Pro, should he do it with the 5/3/1 percentages for every movement or are the percentages different for Bench in the Squat-Bench day, as they are in the 5/3/1 for Beginners?
Thank you for your time.
