how to keep the upper body from slipping on the foam roller?  

So excited to discover your foam roller reformer class and just completed the class and feel so good! You are so right about the foam roller opening up your spine. I am 74 years old with about 12 years of pilates practice and had no problem getting on & off the roller and doing all of the exercises. Expertly cued as with all of your classes. Using the foam roller for footwork helped me feel my abs way more than w/o the roller. I will definitely keep this class in my favorites and return often. Thank you🤍
