Hi all, Good Suggestions and much appreciated:
Got my newbie lifter 11 year old boy on 531 for a month now. Because of age and limited time he is only doing a bench day, and a squat day. Bench day currently has no "real" assistance work, but after his 531 sets he's doing some rows, military presses, and upright rows for giggles. Squat day has no real assistance work either, but after his 531 sets he's doing some RDLs. Two weekly workouts take about 30 minutes each.
Started light. Think it's working because his AMRAPs are now in the medium teens in just the first cycle. Plan on bumping training weights a few percent If he gets over 20 reps. Even though his maxes are a tiny 70# & 120#, I plan on using the full 5#/10# monthly training jump since he's enjoying newbie gains.
Yes, 5x5 would be easier and maybe better, but my idea is to get him used to 531 which he should be able to use basically forever.
