High-intensity interval training (HIIT) is a form of exercise in which you alternate between very intense anaerobic periods and slower recovery periods for a shorter, more efficient workout. The high intensity intervals should be performed at near maximum effort.
150 seconds of intense exercise can burn as many as 200 calories over the course of the next 24 hours thanks to a boosted resting metabolic rate. Just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.
This is not a workout you can do while reading a magazine or chatting with your friend. Because it’s so short, you will be working hard the whole time. The trade-off is this format offers seasoned exercisers a new challenge and new exercisers a quick way to see results. You may be in pain, you may be sucking wind, but you definitely won’t be bored!
Core strength exercises strengthen your core muscles, including your abdominal muscles, back muscles and the muscles around the pelvis. Strong core muscles make it easier to do many physical activities.
