So I asked yesterday what tool you could use to correct the "knees forward of the shoes" position. Meet Mr. Bench (not Kurtis)
With the toes of your shoes slightly under the bench, squat. You'll be surprised how it changes your squat. The first thing you'll notice is that your balance seems gone and that you have to reach way forward in order to not fall over backwards. After a couple more tries you'll figure it out. Grab the bench and give it a try.
Tomorrow is MIMOSA SATURDAY -- don't miss it!
