Joint health gets marketed heavily in bodybuilding because lifters eventually start feeling things. Collagen, fish oil, glucosamine, sleeves and other products all get discussed but supplements shouldn't be the first line of defense against poor training habits
*Load management matters
*Technique matters
*Exercise selection matters
*Recovery matters
a sleeve can make a joint feel supported but it doesn't automatically fix the reason you have pain if something consistently hurts I'd rather figure out why than simply cover the symptom and keep loading it.
