Interestingly, if we're limiting our scope to only the IPF raw world championships (recently held in South Africa)- there is/are only 1-2 obese powerlifting champions (both in the superheavy weight classes- male and female). Everyone else is in shape...really good shape. What's the problem with powerlifting? Multiply, the IPA, westside barbell, etc. Then again, none of that matters in my opinion.
Multiply powerlifting, the IPA/APF/UPA/XPC, etc., and Westside are not real powerlifting. They are farces, where obese men can flourish. Take off the gear, walk the weight out, use a 2hr weigh in and squat below parallel and you'll see these guys/gals who are overweight get destroyed by their in-shape counterparts who have been doing it right.
