Keep heels on floor when squatting saves knee strain
I do a lot of squatting and lifting at my job, and lately my left knee feels a little "strained" for various reasons. But today I read an interesting article that says to keep your heels FLAT on the floor when squatting and lifting rather than "leaning" forward on the front of your feet. Says that this will prevent a lot of straining on your knees, which makes sense. I tried it a few times already and it seems like it will help; takes a little practice to get used to the new "technique" and balancing but it should help!
