HiiT stands for high intensity interval training. HiiT is an exercise method in which you switch back and forth between short intervals of high intensity exercise, followed by short rest or recovery periods. Some HiiT courses may include a kettlebell.
The benefits of HiiT training are several-fold. Probably one of the biggest benefits is that HiiT usually lasts only 30 minutes. This enables just about anyone to be able to get in a great workout regardless of their busy schedules. After all, we can all wake up 30 minutes earlier to get in a workout.
The best thing is that this short 30 minute workout will probably be one of the toughest you will ever do. By working at close to your maximal heart rate, you will be burning the most calories, and causing the most physiological changes to your body that will be beneficial to fat loss.
Not only will you burn fat during your workout, but you will continue to burn fat throughout the rest of the day!
