This $6 Cyber Monday deal saved my knees and will replace your foam roller and your massage gun

I am a fragile man. Emotional instability aside I also have very injury-prone knees, primarily because until I hit 30 my idea of injury prevention was a couple of beers at the pub after a ride to keep me loose. 

However, now, if I don’t hit the gym once a week and stretch I really notice my patella tendons get sore. Foam rolling at the gym is a must for me but sometimes after heavy blocks of training I need to do some at home too.
