Posture is one of the darkest problems of a senior. They may not notice it but in their younger and more glorious years, they may have slouched too much. My grandfather had this problem when he was still alive. He experienced a lot of strain and a lot of problems with his lower back and shoulders.

What seniors need to work out on is their posture. They need to sit up straight or stand straight to attain a good posture. They have to relax their muscles and bones before they get used to being in a slouched position.

To encourage this, you should try to have one ergonomically designed chair for them to sit on. This will help hone their posture back in shape OR you can purchase a posture correction machine. I read a couple of reviews from machines and they work pretty well.
