I would recommend that they 1st compete raw without any suits for at least a meet or 2 and to keep training the raw lift even once they start using the suits. Too many lifters rely on the suits to get big lifts but if u do the math; big raw lifts + suits = really huge equipped lifts. Without the raw strength to back you up the suits can only get you so far.
On occasion, if my legs are really sore I sometimes will do rack pulls. The most I lifted on rack pulls is 765 for a set of 5. I really don’t see much if any carry over as that is not a weak point in my lift.
Once I started competing I first looked up to John Fraser because he had a great bench and had a muscular build like me. Latter in my powerlifting career I admired Jeff Becker because he was in my weight class and consistently broke records and dominated the sport.
I never even knew the sport of powerlifting existed until I looked up bench press records when I got the internet. I even lifted with my t-shirt off in the basement in order to see how much I could bench raw with no shirt.
The biggest problems is trying to lift too much weight with bad form with too short a time under tension. People need to lighten the weight and use stricter form and really work the eccentric part of the lift.
The one major change I need to make is to fill out more so that I can compete at the top of the 90kg class. I am able to easily drop 15+ lbs in 2 days to make a weight class so I need to let my weight slide up to about 215 lbs.
