• One of the easiest exercises for leg strength and balance is Sitting and Standing. Simply sit down on a chair and stand up as quickly as you can. Do this as many times as you can without becoming dizzy. Start off slow and gradually build up the number of times that you can stand up and sit down.  
• Standing next to a table or a chair, with one hand on the chair or table, raise one leg (without bending the knee)  about 6 inches off the ground, hold for a few seconds then do the other leg. Do about 10 or 15 times a day. Make sure that the chair that you are holding on to is sturdy.
•  This is similar to 2. Standing next to a table or a chair, with one hand on the chair or table, pull your leg backward (this time bend the knee)  about 6 inches off the ground, hold for a few seconds then do the other leg. Do about 10 or 15 times a day. 
•  Standing straight up, take one step forward so the heal of foot moving is touching the toe of the other foot.
• Now do the same thing with the other foot. This is like walking on a high wire act without leaving the ground. Walking heel to toe is a good balancing exercise but make sure that when you start out do it close to a wall to prevent falling. 

When doing any balance exercises, be careful not to fall and stop immediately if you begin to feel light-headed or dizzy.
