I am also having trouble logging sit ups or abdominal crunches. I put in 1 set of 50 and zero weight, and I got an error. Perhaps the systems definition of a sit-up and crunch is different than mine. Also, I don't look at it as a set. I do as many as I can, and perhaps it's a modified form of crunch. No weights are…
Though most of us don't considering Yoga as a way to burn calories, it is very beneficial for stretching and strengthening your core. I don't know how to add it. When I tried to search for it, I got no results; when I tried to add it, it stated already exists! Any comments, ideas, or advice out there?
