One type of interval training that I love is Tabata. It is a high intensity interval training, or HIIT. In other words, you will be very, very tired at the end of this workout. The great thing about Tabata is that each session is only 4 minutes long. You work for 20 seconds, rest for 10, and do that 8 times. You would normally do four sessions, equaling a 20 minute workout. Not bad for the person on the go who claims to have no time to work out. You can choose any exercise you want for each session. You can add weights, only do body weight exercises, whatever. The only thing is that you have to go as hard as you can for those 20 sec, or you don’t get anything out of it.
Here is a website explaining more:
Tabata is a quick, very effective, high interval training technique. Beginners should probably not start out with something so taxing on the body…unless you like not being able to move the next day.
Stay sweaty, my friends!
