Your deep secondary muscles are left untouched. You should begin exercising on your secondary muscles to strengthen your foundations and live a pain-free life.
I started I-Spin 3 years ago and have enjoyed a pain-free life. Many of my New Zealand friends take up I-Spin with great results too.
I am 75 years old. I use I-Spin every day for 5 minutes and I have no pain.
I been building up deep secondary muscles through I-Spin instead of going to the gym. Since April 2021, I never had any injury. It is a perfect tool for the warm up before the core exercise.
