For those who can see, whether wheelchair users or not, the screen, a touch screen, has, as far as I know places to touch which will set up level, speed and time. There is one other gym member with sight impairment, but he can still read large print so will, as far as I know be able to locate the position and colour of places on the screen .
CV = cardio-vascular
Most of the strength equipment - chest press, shoulder press, lat pulls, leg press and so on are not a problem; it is just taking me a while to get used to where to put the pegs in and how to adjust the seat etc. The benches are cumbersome to raise and lower, and free weights are only in even numbers - 2, 4, 6 kg, so the staff kept back the old 3s, 5s, etc for those of us who need them!
