@Anonnymus123 - The INZER wraps are the best for offering support, nothing comes close, I agree.
I managed to umm... well.. "find"... a pair of INZER wraps at my gym and was using them for a bit (Careless YOLOs always be forgetting their high end gear at the gym.... a little warm water, hand washing, air dry, and you got yourself some new wraps, straps, bands, and whatever else. I give zero fucks.. I keep that shit when I find it). The re-wrapping after each set gets annoying but I found it did offer great support but for my own knees (personally) just keeping them warm was good enough. If your going heavy as hell then they are great to use. I did find to get that good level of support I had to wrap them way too tight which ended up causing odd pain in my knees some reps, it felt off, so I ditched them.
Now a adjustable knee sleeve would be the best of both worlds.
@ The OP
Take a look at this video:
Your knee placement/movements might be off, or possibly your core. My core is fairly sound but my knees were still flinging around and these tips did help me in getting them stabilized. The belt squat thing felt strange for me, so I used two quarter plates instead and positioned them in a way at the outside-end of me feet where I could think about rounding my toes/feet out towards them, pushing off, and then subconsciously push out my knees at the same time (I don't recommend that, since its my own personal hack, I would have to show you a picture of how its done). I would do this with low weight going extremely deep to get the good tension on my knees. But overall his tips helped me in the steps to build up strength in my knees for my back squats.
The Next big YOLO trend:
I seen two jacked up Asian dudes on roids with this thing. Evreybody was crowding around like kids in grade school with the dude coming with the Pokemon cards for the first time. Regardless of the fact dude hacks the weights with his roided pizza back and face, people will still impressed with his toy. Ended up seeing two more YOLOs with the Sling shots a month later...
The Bodybuilding industry is full of scams. The basics haven't changed since the 70's and 80's. Literally. Aside from a few subtle new breakthroughs in supplements and maybe some nutrition hacks. Your not really fucking with the fundamentals. Everything that is coming on-line is just fads to take away money. You see rookies with too much money, not enough patience, decked out in all the trendy stuff thinking it will get them gains. I was the same. I thought you had to drown yourself in 50 supplements and wear under armor from head to toe to get gains. Its all BS.
Learning the simple foundations is all you need. Minor tweaks to adjust things for your own personal situation but that's about it.
