So, awhile back I saw a friend squatting with plates underneath his heels and I just thought that would put extra strain on your knees so I just blew it off as another fad. However... I was scanning throught the Encyclopedia of Modern Bodybuilding and came across the Squat section where Arnold describes how he sometimes had to do the same thing because his torso was so long it put a lot of extra strain on his lower back to do it regularly, unlike Tom Platz who because of his height was naturally built for regular squats.
I tried it today, after being out of the gym for a few days because of the flu. It felt amazing! I didn't feel the strain I normally do on my lower back and I was able to lift just as much as I had back when I was at my strongest with my legs. And after getting done, my back felt great still, I felt I could have done deadlifts as well but didn't want to overdo it.
I just wanted to share with you guys my experience and how I'm going to incorporate it every time I squat now. Anyone else out there try this?
