If we slow the movement down, you can clearly see the athlete extending the arms as he uses his legs to pull himself into the squat position. The bar does not move upward at all. If you have difficulty getting yourself under the barbell, I highly suggest this drill, and once comfortable, push yourself with the loadings understanding that newtons law states that the bar will fall at the same speed no matter the weight, if we are quick enough to get under 95 pounds, we are quick enough to get under 200 pounds. The only question then, are we strong enough to catch that 200 pound barbell. Give this drill a try and post your attempts and let us know if this drill helps you to get under that bar quicker with more control.
