You can try the free workouts and then pay for the ones you're interested in. It's $5/month. We've found this works well and lets us get everyone some routines at least.
Basically - everyone has a foam roller. No one knows how to use it. Pick a routine based on what your goals are (working out, recovery, general low back pain) and we show you the movements to guide you through a routine in 15 minutes or less.
