Kristy practicing her squat.
Very small errors in the mechanics of our squat at unloaded, and slow speeds are magnified with load or speed. When trying to get our best Tabata squat number we often loose perfect technique. It is expected. The problem is that if we spend thousands of reps reinforcing poor motor recruitment patterns, when the time comes to lift heavy weight we don't understand why we can't maintain our technique. Try this. Video yourself trying to get the perfect squat at slow speed. If you see any errors imagine what they look like at high speed and heavy weight.
Three rounds for time of:
