If you want to try HIIT I suggest you do it properly, timing your exercises and really giving your all. I haven't stuck to them (have a more comfortable alternative), but when I tried Tabata I was stunned by how much it can take out of you. I actually couldn't finish a full round of exercises - which if you read the description sounds laughable - a mere 4 minutes. And I am reasonably fit btw. It's completely different from other exercises you may consider "high intensity".
