10 Minute Beginner Core & Cardio Slide Board Workout

Gail! loved it..I have had my board for a few months now (more like 6-8 months) I am finally interested in it..!!

I'd love a whole room covered in this !

What muscles does this work?

I am new at this but I don't slide smoothly why. And I pulled my inner side of my left leg. So how can I slide easier?
Anyone can help

Where do i buy a slider?
