Improve the rest timer
I was working out tonight on the versaclimber at my local gym and wanted to do sprint intervals of 30 seconds while listening to my music.
I could not do this because the rest timer didn't warn me that there were only 10 seconds left. I was waiting for a ring or to alert me but it never did. A countdown would have been nice too. But I wouldn't of wanted it to interrupt my music.
Timed workouts are the best workouts for online training. The client can stay on track and push themselves (reps don't do this)
You really need to step up the rest timer. I wanna implement it in my training but the performance isn't there.
