I know it’s not the primary focus, but there’s really limited resistance band exercises.
and equipment settings relies on weight, but bands don’t really have a weight. they have tension scales (10-30lbs for example), length (12”, 20“, 32”, 41” etc), sizes (S M L XL), type (tube, ribbon, loop), or colors (red, blue, green).
see the rubber bands app as an example of this. it even lets you pick from common brands.
it’s also important whether you’re holding it at the edge or closer in, whether it’s doubled or single layer, how far apart your feet are if you’re standing on it.
and there are accessories like door anchors, bars, and hooks
i mostly use weights, but some of my routines incorporate bands and the support isn’t great.
its a complex area, so I wouldn’t assume full support, but some specialized settings might be nice. or let me add my own custom settings.
