An expert shares three stretches "everyone could benefit from"

It's often said that fitness operates on a "use it or lose it principle"—if you don't keep your muscles and joints moving, they can weaken, tighten and become more susceptible to injury. That's why regular activity is so important.

However, you don't need to commit to a daily HIIT session or long runs to maintain your body’s flexibility and strength. Sometimes, a few simple stretches can be a relaxing, enjoyable and effective way to keep your body moving smoothly.

To get you started, Caitlin Donato, director of fitness at the Pritikin Longevity Center has shared three stretches that "everyone could benefit from". These stretches are designed to improve posture, prevent back pain and provide relief after long periods of sitting.

You can perform them in a circuit as a quick four-minute routine. Hold each stretch for 20 seconds (on each side if it's one-sided) and repeat the sequence twice.

How to do these three daily stretches
