WHAT IS HIGH-INTENSITY INTERVAL TRAINING?

High-Intensity Interval Training, also called HIIT, is an intensive workout that includes interval training activities.

During this practice, the heart rate reached 100% and was used by elite Olympic athletes to enhance their performances. HIIT can be incorporated into various activities, such as running outside or on a treadmill, dancing, rowing machines, stationary bicycles, etc.

Using a stationary bike and pedal as hard as you can for 30 seconds. Then, pedal at a slow speed for 2 to 4 minutes.

Stair running,
Burpees,
Pull-ups, etc.
