Eileen M and Deborah R the roll over into jackknife can be a challenging move especially in the case of tight spinal extensors. One modification I like a lot for people struggling with the roll over portion is to bend the knees into a rolling like a ball shape, start the reverse curl and then kick the legs to use momentum to get the rest of the way over. In the jackknife portion it is helpful to focus on using the back and hip extensors to achieve the line while also pressing into the arms to stabilize the shoulders and anchor the upper body. Hopefully, that is helpful and please let me know how you go.
I always get excited to wake up and see a new class from my favorite Meredith, but it’s extra special when it’s an advanced workout! Love love loved!! Xx
