tfw...I think you are talking about HIIT, or High Intensity Interval Training....works great, can do it quick, but it IS a bbuster....also known as "burst" training.....I'm out of shape, always trying to get in "some" exercise is, and thought that would be perfect for me...get it done in 10-20 min...every other day.....but man is it hard
