Tabata is another form of HIIT workout except it is done is shorter reps and rest times. It is not based on how many reps you do, or how much weight you are lifting. The famous Tabata workout is based on timing, usually being 20 seconds on and 10 seconds rest for at least 8 sets. This workout will not get you bored since you are always switching exercises or resting. And the rest is an active rest so that you are not just standing there.
