The front desk guy at my gym said I was loading the leg press backward, and the fix took 10 seconds
I'd been putting the pin in the top slot thinking it was lighter, and he told me that's actually the heaviest setting on that machine. Flipped it to the bottom and did 3 sets of 12 feeling like a normal person instead of dying. What's a machine at your gym you found out you'd been using wrong for months?
