If your knees are free of pain, it really gives you license to be active.
And activity will help your heart work better, help keep your brain in tip-top condition, and improve your overall quality of life as you age.
But if your knees are painful, it limits your life in many ways that are bound to have detrimental effects.
Unfortunately the less you exercise worse you’ll be in the long term, being generally fit helps your body cope with higher levels of pain.
With knee pain avoid stopping exercise for even short periods of time (even a few days of inactivity is too long).
If you can’t manage to walk 1 mile, walk half a mile, if that’s too much walk 100 yards, avoid stopping exercise completely even if it’s walking to the kitchen for a cup of tea/coffee you’d rather a loved one make you.
Keep active it real does help with pain long term.
