I use SS's knee sleeves as my elbow sleeves. It's the 7mm Rheband (the blues). You may be able to pick them up at jakals gym. I know Titans makes a similar pair.
I have the heavy elbows and the super heavy knees. The knees are a bitch to get on and off, but worth it. I only use them for my heaviest sets and then it's a race to get them off. I only use the elbows when my joints are bothering me. I wouldn't say that they help with healing or preventing tendinitis, but they make lifting more comfortable.
Good to know... Been using some inzer knee wraps for my heaviest squat sets but some days my elbow joints just feel shot and I think this will help for longevity
When you squat you should pull the bar into your back and that puts a lot of pressure on the elbows. It's not uncommon for plers to have elbow pain for this reason.
