Thanks, Erica! I’ planned to purchase the pack, but since it’ll be my first time using a band; I wanted to ensure I’m using the mist effective suze/weight. I’ll guess I’ll see when I try them for the first time. 😊Thanks again!

Thanks for your reply! My question isn’t anout where to find the bands. I’m asking if I should use a specific band (ex: X-Light, Light, Medium, Heavy or X-Heavy)? Thanks!
