That’s pretty broad mane.
So we looking at stuff like squat, deadlift shoes, wraps, straps, sleeves, belts, sexy clothing (cos who doesn’t do better when they look sexy). Performance enhancing drugs, calibrated plates and expensive barbells for training.
Competition legal clothing and equipment cos never mind doing your best you won’t even compete without them.
Hell you’ve not evened mentioned training even looking at it as one variable. No training no stimulus no adaption.
A program is a variable. Are you on one? Is it a good one? If u want to best results it better be some JoeyFlexx Boris Sheiko looking program.
