Michelle Bridges: High Intensity Interval Training is awesome - Women's Health & Fitness

High Intensity Interval Training (HIIT) or ‘the express workout’, where you work your body at its maximum effort for a period and then recover for an equal period, has hit the spotlight because of its ability to burn calories quickly.

"HIIT is what I’m loving in 2014,” says fitness guru Michelle Bridges. "This style of training is awesome and is the way I work out. You can do it anywhere, including a small hotel room and is the basis behind my Project series DVDs.

"They consist of super-high-intense intervals of cardio and strength with periods of rest. What’s more, you don't need any equipment to give you a full body workout."
