A client of mine recently told me about this video. It holds true to what I tell many of my clients.
Notice how stiff you feel when you wake up in the morning. Lack of movement does that. It leaves you feeling stiff. If you want a better range of motion, you have to get moving. Even a little movement will help you get going. Moving your joints, moving your muscles helps to get you to feel fluid again. So let's get moving!!!!
If you are feeling too stiff, and it is difficult to get moving, maybe a massage would help? =)
