No crunch! Let’s reach

You are creating so many disproportionate forces vectoring across your spine every time you crunch. This demonstration keeps the spine close to the natural curves that has better neurological as well as muscle engagement…without the bad forces trickling in the system. I have regressed from the standing ball slam to a shorter lever / moment arm to keep “enter-exit shorter. This “tricking the system” has a condensed benefit. When you get done with this go into a prone bridge to “reset the facets back to their natural extension.
