My sister is a novice to the world of technology having spent most of her adult life teaching fitness. Recently she had to attend a remedial driving course (or pay a fine and have points on her license for doing 50 miles an hour in a 40 mile zone). This involved using a computer with a mouse and she said she ended up with her arm so far over to the right that she fell off the table!
However, times are changing and together with the Nintendo Wii-fit you can exercise from your laptop. You can check her out her on-line lessons here!
