Swimming in a straight line!
As a "for instance" I knew it was very important for me to keep fit as the legs and arm weigh over two stone in total and I would be lugging them around all day. I was restricted in the type of exercise I could take part in and decided that swimming was the best form of exercise.
Have a look at the video to see how I bought a large rubber fin and modified it to fit over the knee of my left stump. It really works well and I normally swim up to 2 miles a week.
I have now developed a more painless and secure way of fixing it on - please click here.
