What should I do for a cool-down after interval work?
I recommend a minimum of five minutes of cool-down at a low intensity after your intervals. I also recommend stretching afterward because the leg muscles will be tight after an intense session. Quad, hamstring, calf, and low-back stretches will help. Sometimes muscles are too tight to stretch immediately after your interval session and so you might want to walk around for a bit and then stretch later in the day.
Wrapping it up
There you have it. Interval training is an efficient and effective training method that will help you improve your aerobic and anaerobic capacity, your performance, your recovery from short and intense bouts of work, and all in less than one-fifth the time of traditional aerobic conditioning. Intervals are tough but worth the effort. Give it a try and see what you think. Good luck with your training!
