Virgin Active, a world-class fitness brand from the UK, recently launched Sprint, a new indoor cycling class designed for health lovers who are time strapped but love challenges.

Available at all five of its Bangkok gyms, Sprint is a cycle workout built on the science of high-intensity interval training. This allows nine times the fat loss of regular cardio training in a 30-minute class –burning up to 500 calories! The body also continues to burn more calories for hours after the class.

As the class begins, you will warm up your climbing muscles, then hit a series of full-on hill climbs that test your strength, and cycling time trials that test your endurance. There will be time for recovery, just enough to give you the energy to push through the next challenge.

In addition to burning a lot of calories, muscles also get toned from this class. It’s not just about the butt and thighs – indoor cycling gets all your leg muscles working. All that spinning sculpts strong calf muscles and targets your quads and hamstrings.

Sprint is a quick and intense style of training that returns rapid results with minimal joint impact. It improves your cardiovascular health because it gets your heart pumping and gets blood flowing, thus keeping heart problems away.
