5 Ways to Warm Up Your Joints

As we age, our joints may hinder us from some of the things we love to do. Repetitive motions, past injuries, or just years of wear and tear, can all lead to affecting our activity levels. Some may just accept it as a simple fact of life, but it may not have to be that way. The best approach is a proactive one: gentle stretching and a joint-focused warm up before working out.

Yoga Poses for Joint Health

Practicing yoga has kept yogis strong and limber for thousands of years. But, why? How can simple movements be so effective for the body? Well, yoga does these amazing things: it not only supports flexibility, but also strength. So, as you’re stretching, you’re also supporting. For those with certain joint concerns, this can be a blessing! When practicing yoga, the body goes through its entire range of motion, which allows movement to joints that may normally not be used. Because yoga doesn’t neglect joints, it can provide full body support.
