I would call this a fair-size defect, frankly, not just for me.
What I continue to like is that it keeps track of the workouts I have done - not how well I have done them because there is no way to measure this - but it knows where I am in the schedule. And I like that I can choose on any one day what I want to focus on.
So what I'd like in the expanded version:
* instructions on adjusting exercises for those with disabilities. Better, a way to plug in the fact that one has certain issues and have the program adjust for me.
* coordination of individual exercises as discussed above.
* a wider selection of music.
* slow tutorials - I tried a "step turn" move today and really could not follow the tutorial. Just going through it slowly a couple of times would work. Because it involves turning and not being able to keep my eye on the television I needed more help.
