Unloaded slow roll ups or some easy unloaded cat / cow flossing into spinal flexion can certainly be restorative, but the problem lies within the individual context of each person executing rounded spine movements, in where they could also be a poor idea, or one that slowly compounds over years, or decades.
Instead, he leaps, flip and
rolls about each level, using his
slow - mo ability to avoid bullets and
unload an unnervingly accurate volley of return fire.
