Interval training is simply alternating high energy bursts of exercise with lower intensity bursts. Its a great way to get out of a workout rut, burn more calories during and after your workout, increase strength, endurance, and speed.
One of the simplest ways to do Interval Training is to go for a walk/run. Run for 30 seconds, then walk for 30 seconds. The time of intervals can be changed to 1 minute or even longer. Studies show that the shorter the intervals, the higher amount of fat loss.
Tabata Training is a very popular term for athletes and in the fitness industry. It was a workout originally designed for speed skating and cycling. However, the Tabata method can be used for any form of exercise. You perform your high intensity burst for 20 seconds, rest for 10 seconds and repeat for 8 cycles, totally 4 minutes. In an hour you would do about 12-15 rounds.
Is there an ap for that? Of course there is! If your taking your workout outside download the Tabata Pro Timer to your phone.
