Susannah R Open Leg Rocker with the roller is a total bugger... but it's a great tattler - I know exactly what went wrong almost immediately when it doesn't go my way, and that always steers me toward what needs refinement. Thank you for watching!
Sharon C Indeed, the rollers can vary in density, and that makes a huge difference in the work! For a work out like this one, I generally recommend a medium density roller, or hard if that's all that is available. The soft may not provide enough feedback. That said, I say try them all!
