Back support
I have been going for 18 years with 2 herniated discs, thank goodness for Chiropractors. From my experience, the excercise you get from riding, as long as you are moving with the sled is good for you. Any mobility you can give your back, the better & stronger it will be. It is the lifting you have be cautious of as well as landing any jump, make sure you are standing. I use an AC back belt, but I am sure it is the same. Adjustable tension left & right, nice & wide, with a pad in the lumbar area. Initially after my injury, I could hardly walk without difficulty. After a number of months of treatment, I began to ride & the treatments responded better than expected. My chiropractor said "I don't know what you are doing, but keep doing it", you should have seen the look on his face when I told him. Just be reasonable about how you ride, you should be fine. After being off for a year, you will be sore, but don't let that stop you, you will eventually regain the strength.-Mezz
