"To be prepared beforehand for any contingency is the greatest of virtues.” ---Sun Tzu The Art of War
During maximal attempts, it is very possible for technique to break down which increases the risk for injury. For example, here we see Chen Xiaoting (53kg) with a gnarly save at 101kg to win the snatch gold medal at the 2015 world championships. A sub-optimal pull resulted in her catching the bar off balance and saving it by rounding her back and twisting.
Normally this rounded position could result in lower back injury however Chinese weightlifters insure against this situation by incorporating rounded back deadlifting because of their ability to work the erectors through a greater range of motion not covered by traditional deadlifts and pulls. While one must gradually build up tolerance for such movements, the end result can prevent injuries when technique is not perfect. So make sure to train for contingencies and strengthen the whole body to secure your position.
Beginners following a strength training program, usually don't train under supervision and attempt to lift weights that take their maximal effort, especially when they go beyond their bodyweight, which may break down their technique.
In my case, I was squatting and deadlifting weights 1.2 to 1.5 times my bodyweight with poor form, in StrongLifts 5x5 program. Many times I simply skipped sets just to be safe from injury. I know deloading and working on the form is best way forward. But in spite of conscious efforts to maintain form, there is a strong possibility that in the future, under heavy weights, my technique may break down and I get injured.
Question: Just as a safety measure, should I not prepare my body for it by incorporating Rounded Back Deadlifts? If yes, how to integrate them into StrongLifts program?
