Kevin and I both have a fail in the above video where we catch at the bottom with lousy back structure. Put another way, we’re trying to squat with a rounded back. As you can see, it doesn’t work.
The annoying thing is that it can work. At lighter weights, you can get away with a curved back in your front squat. Despite that irritating fact, you should NOT catch lig cleans wo a bent back because then you’ll develop that habit and when you go heavy it will appear despite your best efforts.
Don’t round your back… you’ll lose all your friends… and probably more important, you’ll lose your barbell.
