The first posts were in various other threads. Discuss, speculate and debate Amber's ability to exercise and move, what she would be capable of, and evidence of her lack of mobility here.
I don't think she should be trying to move around like that, honestly. One real fall...we know the outcome. She would need professional supervision for anything more than walking, and we know how much she respects professionals.She literally owns a PS4, Switch, and probably an Xbox. I don't know why she can't play Just Dance on one of those since she "loves to dance" so much. Even if she can't finish a song, that would be a good goal for her to work up to. Just do it for as long as you can each day until you can finally finish a song, and it's something you enjoy so it won't feel like working out but that little bit of movement will do wonders.
As said above swimming is also an excellent forum of exercise but she is too embarrassed to go to a public pool which is what she would need to do to get adequate exercise.
