I feel like Powerlifting has become such a crap shoot. You have ppl doing ultra wide sumo on DL, crazy back arch on bench, squat suits, wrapped knees, ultra wide foot placement low bar squat blah blah. To me these lifts no longer even remotely resemble what I do in the gym. That being said I love John Haack - conventional DL, relatively narrow/normal grip on bench, doesn't the dude even high bar? Wish that shit was just the standard.
I have started this year using knee sleeves once I go above 400 lbs on squats. At 37 it keeps warm and secured, better for longevity.
If there are any real complaints for strength sports (I've done strongman as well) are the high usages of PEDs. Not that I am against people using them but it makes it difficult to have apples to apples comparison, particularly when competing.
