188.8.131.52 Strength specific work – Pull strength
If you struggle to keep your shape as you break the bar from the floor, then you need to do more work from the floor. Pulls, Dead pulls and Pulls to the knee are the answer for you, all covered in the pulling section.
Pulls should be trained after the classical lifts. Pulling strength arrives after significant volume and loading, and as a result a protocol of 5x5 at 90-105% of the 1RM of the classical lift is recommended.
Keeping the right shape from the floor is the most important part of Olympic lifting, as it ensures that the lifter is in the optimum position to execute the rest of the lift.
