I didn't stretch both legs. I have a needle and can't even pull a dorito on the other leg. I have a bulging herniated disc in my l4/l5 as a result of not stretching both legs the same and tumbling on hard surfaces (gym floor, dead mat) the herniation causes a lot of pain whenever I do simple things. If your back hurts, even just a little, I reccommend going to your doctor to get checked out because if you don't catch what's wrong really early it can cause a lot of damage. Thankfully I did, and it could be worse, but its still going to effect me for the rest of my life.
ETA: I should probably mention I'm not a base.
