Hello,
I have been doing GST for about 2 months. I started experiencing some back pain after a trail race earlier in the year. The chiropractor diagnosed a bulging disk and asked me to stop running and back off on repetitive lower body movements (like crossfit) for a while to let my back recover. He was supportive of me starting this program but has some concerns about Jefferson curls. Not just in my case but the whole exercise. I've been doing as much research as I can over the last week or so and want to go ahead but before I start I am wondering what suggestions you would have to reduce risk or re-injury. Is it as simple as keeping the weight very low and proceeding cautiously? Thanks in advance!
