Unfortunately paralympic sport association has always been pretty poor on this front as they tend to know only of clubs, not facilities outside of clubs. They sent a list of clubs I could join but most addresses were in London, with the closest being a mere 285 miles away. They ought to be more interested in people who want to get a bit fit but do not want to become olympic athletes, but with time and budget restraints really they want to know about the olympic hopefuls.
The reason it has to be done from the floor not a weight bench is because if you don't have the strength of torso to correct a side to side twist then you'd plummet off the edge of the narrow weight benches. People with able bodies do this as a matter of course without even knowing they do it because it's small muscle corrections, but when you can't do it you soon find yourself falling out of bed! It would be too dangerous to set up on a bench unless it was really wide, or I got someone to strap me down to the bench. One slight flicker, maybe one arm is stronger than the other and I lockout on only one side and that would throw me over on the floor with the bar on top. Any bench would need to be minimally
3 feet wide, and at a height I can manage to get onto, whilst being so small it doesn't take up any space in my tiny house!
I think it's going to need to be the floor for me.
I need to find me a metalwork class, any time I have these problems somoene always says "get someone to make it for you, there are plenty of blacksmiths around" but I bet they haven't ever actually tried to use
one, cos I have and it's a total blank.
