I hurt my back today doing levers and vertical jumps.
I was doing some integrated training with 6 sec levers (my max for the variation is probably 20 sec.) followed by a few verts.
I think what got me was slouching before the training session, and between sets.
I was playing call of duty before hand for a couple of hours and I was slouching the whole time. I workout at home so I turned it off and started to train.
I warmed up of course, but between each set I sat down with a slouched posture.
I think it was the combination of the slouching for hours before training and between each set combined with an exercise (front levers) that take a lot of spinal extension.
When I went to stand up after a set, thats when I hurt it, not during an exercise. It's right below my shoulder blades on the spinal erectors.
I wonder how long I won't be able to train now.
