If cutting weight for sport bothers you folks you would have hated wrestling, boxing or MMA!
True, but yeah mainly water. Sport shouldn't promote dangerous health practices like that. I competed in Power Lifting at 3-4 kilos above the class and did the dehydrate/rehydrate/eat a cow thing, and hated it. I feel for jockeys, ballet dancers, skaters, gymnasts, etc that have to keep
hard weight off.
I went from a 92 kg power lifter to a 67.5kg kick boxer in six months. It was hard weight lost via intensive training. Amazing what fear of competing as a heavyweight at 5'8" will do to your motivation!
Speaking of motivation, million $$$$ payroll ain't bad.
I could cope on the F1 payroll, but it ain't right.
