I have to disagree with on this. For the matter that he is an Olympic lifter reviewing a powerlifting regiment is pointless. That no different than a Cowboys fan going onto a Steelers forum and ranting about how horrible they are. I will never put down a person for their beliefs on something until they start doing it to someone else. 5/3/1 is not a program for Muay Thai. He is correct on that. 5/3/1 is if you are planning on competing in a meet. And for powerlifters being idiots, I'm a powerlifter as well as a firefighter. My powerlifting training has significantly added strength in all aspects to do my job more safely. If you want to argue the point, please go to the fire academy and get certified, suit up, and make entry.
Although in early 1998 he was still able to do five reps in the bench press with 495 lbs, three reps in the squat with 855 lbs (with no suit and no knee wraps), and three reps in the standing press with 405 lbs in training, while traveling with the World Wrestling Federation , he never returned to compete again in official championships in favor of his wrestling career.  He weighed 380 lbs at that time, and his right upper arm was measured at 24” by Terry Todd .  By basically ending his lifting career at the age of 26, it is probable that he never reached his full physical potential as a professional lifter. Henry remains the youngest man in history to squat more than 900 pounds without a squat suit as well as the youngest to total more than 2,300 pounds raw  – he's the only person ever to have accomplished any of these feats at under 25 years of age. 
I totally understand what kind of job you had. I work at a Wally World distribution center. Started in shipping, loading about 3 to 4 full semi’s a day. Didn’t know how much weight I loaded. Then switched to non conveyable. When in dog food, I’d stack about 60k/lbs in 12 hours. That was MUCH easier than shipping. My first year, I struggled. Then I talked to my bro-in-law, who is a personal trainer, found and I started to do good. I was taking creatine and C4 prior to work, and took an Animal Pak with UniLiver every break, while eating protien every 3-4 hours. This brought me to Muscle for Life and The Books. I’m in maintenance department now, and are about to join a gym. I’ve been wanting to get the Legion multi’s and switch to Legion supplements. I’m about done reading BLS, and are gonna start the year one challenge. I’ve aready bought BBLS and Shredded Chef. I get excited every time I think about my goals.
