vertically stacked exercise lists that can be expanded and collapsed to show or hide the associated content. Would be nice if after completing a set or superset or exercises, clients could collapse that set and get it out of the way for less scrolling. Also Clients often have to bounce around their workouts when equipment isn't free at the gym and there's a lot of scrolling up and down. If they could collapse sets and just open them when they are about use do them it would save a lot of scrolling and forgetting where they are in the program.
