Tabata is good - I tend not to opt for it as it's not as "choreographed" as the Les Mills varieties, but it's a solid work out, and it's chopped up into "chunks" which make it stay interesting and the 45-50 minutes goes pretty quickly. I found myself quite energised, and up for a brisk walk or crosstrainer round after it - if I was the jogging type I would happily have jumped on the treadmill for another 10-15 to round out the hour, before doing stretches.
