Sixty-Second Workout

Keep on running! One more minute! PHEW!

This is Sandra Tsing Loh with the Loh Down on Science.

Being healthy can mean a lot of things. Kale juice, spin class, weightlifting! We know how to stay lean and build muscle. But what about bones? Bone weakens as we age, especially in women. So how do we keep them strong as we get older?

Let’s ask Victoria Stiles at the University of Exeter, UK. Her team surveyed the fitness and bone health of over two thousand middle-aged women. How did they test bone health, you ask? Skeletor dead-lifts?

Actually, they used sound! They measured bone density by observing how ultrasound travels through the women’s’ skeletons.

To measure physical activity, the volunteers wore Fitbit-like wristbands for one week. Stiles then analyzed their activity intensity and compared it with each woman’s bone health.

Think you need hours of exercise? Nope. Just a minimum of one to two minutes each day! High intensity exercise everyday, like jogging around the block, is enough to maintain strong bones!

A minute a day keeps your bones in play! Also kale. Always darned kale.
