2014 University National Champion Cody King performing Snatches from Below the Knee on the Blocks with 140 kilos (308 lbs). We use Block work to work on specific positions that the athlete may be having challenges with. The Below the Knee Position is the hardest to master because of the transition point around the knee. Passing the by the knee without contacting the knee is key and critical for success in the Olympic Lifts.
We also use the blocks to develop Starting Power, the ability to go from 0-60 mph as fast as possible. The blocks also allow the athlete not to overly tax their lower back and only concentrate on the Concentric portion of the movement. Unlike when the athlete holds the Bar from the hang position which places a great amount of stress on the lower back and the athlete has to be concerned with Position Strength along with Concentric Force Development.
This was a personal record for Cody in this position. The strength transfer from Block to Floor can be anywhere between 10-15 kilos in advanced athletes.
