You've done a more or less regular aerobics exercise routine since high school. You feel good about yourself, and you know you're doing the right thing by your body every time you get yourself out of bed an hour early to go do it.
It isn't fun, exactly, and it isn't short, but, life isn't all fun and games. You're more or less fit, and though you'd like to be a little more athletic, maybe, you're glad you're not less.
Now everyone's talking about this thing called Tabata. No one did that when you were in college, or high school, either. Is it the newest fad among people who must always be doing something different?
