More often than I'd like when Ipause and resume a workout video, or when I enter my weights and times, the app glitches. The video stops playing, the screen goes black, or the whole app closes. I end up having to restart the app completely, and when I do, the workout starts over from the beginning. It’s really frustrating and makes it hard to get through a session.

LOVE this! My experienced fitness coach contours workouts to my ever changing availability, physical limitations, as well as personal goals. This isn't just another one size fits all gym experience. I work long hours which makes it hard to get a workout in consistently. S2 is the answer! All you do is open the app and SWEAT! The workouts do not require much space and the optional equipment is simple and easy to use. LOVE THIS APP!!

Hello! I've been reaching out via email and and IG. I joined a challenge and shortly after got injured and couldn't continue. I've been trying to see if there is a pause option so that I can recoup the time and start back today. I've just signed into my account to try to contact customer support or something see if I can self-service a pause and to my complete dismay not only cannot I not pause, I also can't cancel the membership. You've collected two months..I realize there was a commitme
