High Intensity Training is also referred to as HIT exercise.
Short bursts
of high intensity activity within a period of exercise can improve aerobic
fitness, insulin sensitivity and muscle strength.
HIT breaks down the stored
glucose in muscles very rapidly, activating more than 70% of your muscle cells.
Just 3 minutes a week of 20 seconds or 30 seconds where you push your body to its
limits is needed. Start with a warm up, then alternate 20 to 30 seconds of HIT with 30 seconds of gentle exercise for 3 minutes.
HIT exercise can be cycling (including using an exercise bike), swimming, running and skipping.
