As a 76 year old elderly lady, my grandmother Michelle, living alone for a while had to brave many heavy luggages and had to walk here and there and everywhere because she did not know how to drive. Although incredibly athletic in her earlier years, after the years went past and she gained weight as well as went down to doing no exercises at all, the lubricating substance between the joints began to wear off. Every time she walked she would find herself in intense pain and found that she could neither bend nor stretch her legs. Consequently she ended up going through an implantation surgery. While she was in the hospital she found two exercises that didn’t inflict too much stress on her joints. 1. Crouching down as much as you possibly can – spread your legs at approximately shoulder width (wider if conditions are quite severe) and rest and lean your back onto a wall surface. Then you start to crouch down very slowly. Repeat this motion for 20 more times. 2. Bending legs up and down. Sit in a comfortable position and lift your legs in a perpendicular motion. Sustain for 10 seconds. Repeat this for 15~30 times.
