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.
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.
All my workouts revolve around the big 3 (squat, bench, and deadlifts) followed by exercises to make me pretty following the big three. This in my view capitalizes on the benefits of both forms of training.
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.
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.
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.
