QuickTime Clips: Exercise for Arthritis | Arthritis Information
I came across this set of QuickTime movie clips that show how to do exercises.
Do You Know Your Exercise Types?:
Isometric - In these exercises, you tighten your muscles, but don't move your joints. This helps build your muscles without moving painful joints.
Isotonic - In these exercises, you strengthen muscles by moving your joints. For example, when you press your knee toward the floor, you are doing an isotonic exercise to strengthen your thigh muscle.
