HIIT Workout, The One Workout You Must Do

HIIT, known as high-intensity interval training, is one of the most important new exercise approaches that has been introduced in decades. Why? Because it’s a workout that can be done in 20 minutes but yet has an abundance of physical benefit such as: build muscle, regulates insulin, cut fat and increases heart function, and it increases the function of the mitochondria in our cells (the battery packs of the cell).

A typical HIIT workout could consist of:

Total: 20 min.

If you think you may be too old for wind sprints, just tweak whatever aerobic exercises you are doing to fit in the HIIT protocol – probably just a bit more intense. If you are not exercising, start walking 3 times per week and work up from there to fast walking alternating with slower rest/walk.

This is a great way to gain health benefits of all kinds without putting in a ton of time.
