I dont recommend wearing a belt…every time you squat or deadlift your “core” muscles are working isometrically to stabilize your trunk…With that being said, as you increase your intensity with the exercise the intensity on your core muscles is increased also…your want a proportionate increase in isometric strength to concentric and essentric strength in terms of the exercise…so i would recommend not using a belt unless you are going to attempt an intensity heavier than your 1RM[/quote]
There have been EMG studies that have shown that wearing a belt actually INCREASES the activation of the “core” muscles. That means they are working to a greater degree. If you think about it, the whole idea that a piece of leather wrapped around your waist is robbing your “core” muscles of any work is kind of ridiculous when you consider the sort of load that those muscles are under.
Does wrapping leather around your forearm increase your ability to hold onto something while simultaneously robbing those muscles of their isometric power? No. Were not talking about a 3 ply squat suit here, were talking about a 6 inch wide piece of leather. Thats it.
I imagine that this myth was started by the same skinny fucks who yell about maintaining proper form when they see guys lifting 3 times as much as they do with somewhat looser form.
“He just squatted 600 lbs!”
“Yeah, well, he was wearing a belt, so it doesnt count, he wasnt using his core. Im going to go do some leg extensions and swiss ball crunches.”
