This 20 second full exertion ( I do record the reps attained ) with a 10 second rest is really strenuous. I do 4 different exercises, back to back, then go through another round, for a 4 minute total time routine. I give a full 2 min cool down, then do it again, with 4 fresh exercises. It’s good to shake things up and use this technique, but I’ve found that the that it is too difficult for most clients and even my upper level clientele seem to have trouble making it through the 8 minutes. Any comments/thoughts/experiences that you can share ?
Agree with the others, I teach a group circuit training class 2X a week and I’ll throw in tabatas once in a while to mix it up. They groan and complain but in the end love it. And because it is based on each person’s level of experience it is easy to modify. I started slow with it as well – 4 rounds first and then worked my way up.
