I suspect that the equipment at commercial gyms (why the weird spelling, by the way?) varies by location, especially for franchises. So why don’t you just call around to the gyms in your area and ask them?
This, basically. IME, “big box store” gyms don’t have much in the way of wheelchair-accessible equipment. But that can always vary between individual gyms that are franchised out. IME, being a wheelchair-using gym rat for almost 2 decades has led me invariably to hospital-based or medically-based “fitness centers”, as opposed to gyms or “workout” places. These places tend to have a plethora of accessible equipment.
I found one local place by searching medical fitness center. Called and talked to the owner. He’s got a pully system wheelchairs can use.
Rehab has such great equip. But, most of the patients I saw were elderly. The equip didn’t get much use. The physical therapists were always busy when I visited my cousin.
If she can’t get out of the wheelchair, she might have issues. Although she could still use dumbbells and things like that.
I used to train with a guy in a chair, but he could get out of the chair, and he had a strap he used to fix himself into place (he had no use of his legs). But when I spotted him, it was a matter of holding the chair while he swung himself into place, then buckling the strap under the seat or the bench, and then he was used to balancing the weight so he didn’t slip.
He was as strong as fuck, too - IIRC he did marathons, and his shoulders were like rocks.
This guy used to work out at a small gym I went to in the UK.
He always had one of the gym staff to assist, but he worked out like a monster.
They used a lot of straps to the equipment (i.e hand bike, cable pulls, etc), and were always adapting.
If I had to recommend one piece of equipment for a wheelchair-user, it’d be the upper body ergometer, or “armbike”. It can be set for direct wheelchair access (the seat is detachable) and used for cardiovascular exercise and/or upper body strengthening. Given the lack of options for cardio for the average wheelchair-user, a piece of equipment like this is priceless. The UBE is a feature of most medically-based fitness centers.
Not quite what you’re asking, but there are wheelchair users in my Zumba classes. They modify the moves. One does the class with reasonably heavy dumbbells.
If you have physio centre for multiple sclerosis patents nearby they might have the machines, my dad can barely walk but does upper body exercises and they have a cycling machine he loves.
