How to burn 500 calories WITHOUT going to the gym: Do this fun activity

A Harvard Medical School study measured how many calories you can shed during a 30 minute session.

And apparently, an 11st person can torch 260kcal by rollerblading for half an hour.

This figure increases for those who are heavier – as skating is even more strenuous when you’re bulkier.

You can also up your calorie burning potential by rollerblading at intervals.

Alternate sprinting and gliding slowly to give yourself a trickier workout.

As well as burning plenty of calories, rollerblading works to tone the body.

Skating is a full-body aerobic workout that tones the thighs, hamstring and glutes.

Apparently, the sport can also make your heart healthier.

Universitat Konstantx researchers found that moderate roller skating increases the heartbeat to 140-160 beats per minute.

This causes blood to be pumped around the body at a faster rate, strengthening the vital organ’s muscle function.
