High intensity interval training (HIIT) is one of the best ways to get fit quick – not just looking fit, but feeling fit, as well.

It’s a great workout for burning fat, boosting endurance, toning up allover and building explosive speed and strength. If you’re looking to get or stay lean, HIIT workouts should show up in your routine between 1-3 times a week, depending on your goals, training intensity and fitness level, or how quickly you recover in between sweat sessions.
