Go for a walk or something. You may think rest is best for your joints, but experts say the opposite: Exercise keeps joints healthy by increasing the blood flow to them. If you're not already doing some type of aerobic activity, like brisk walking, tennis, or swimming, now is the time to start. Aim for 30 minutes of moderate activity five days a week. If you're a beginner or in pain, start by walking for 10 minutes just two days a week and increase the length and frequency as it gets easier.

Do these exercises, which work your legs and important core muscles, three times a week.
Stand in front of a chair with feet shoulder-width apart. Keeping your back straight, stomach muscles pulled in, and knees above your ankles, slowly lower your butt toward the chair, raising your arms forward to help with control and balance. Pause before actually sitting. Then slowly return to standing. Do one set of 10.
