I was working on front levers lately and got confident so I took my parallettes and attempted an assisted victorian cross. I lifted my body just a bit (parallettes are barely 10 inches high) and couldn't do it. On the next morning I was having back pain on my right side while inhaling, also when bending down to touch my toes with my hands. It has been almost a week now and the pain is still there. How can I get rid of it ?
