I wish I knew this when I started personal training…
Your spine needs to be able to segment.
The McGill 3 is all predicated on getting the deep muscles of your core to work, including the multifidi.
And their function is to help create spinal segmentation so your spine can be efficient at absorbing force.
So even before you focus on stability and core strength- you need to make sure your spine can segment.
Loving this set-up for feedback allowing me to focus on moving only the lumbar region - as well as allowing me to use gravity to load lumbar extension!
Give it a try. And if you want more buttery goodness, DM me the word SPINE and I’ll send you a free low back and core strengthening routine.
