I just bought a $2.99 Kindle book called Burst Workouts which recommends very short workouts at high intensities. His main program recommends timed interval training using bodyweight exercises of 30 seconds of an exercise, then 30 seconds of rest, then another 30 seconds of exercise, then another 30 seconds of rest, and so on. You choose a push exercise, a push exercise, and leg or "heart rate" exercise, and you circuit through them in the above fashion. You go through the circuit five times, so that the workout should only take between 10 and 15 minutes.
The book seems to focus on weight loss, which is keen to my goals. I know I need to reduce the calories I consume, and he addresses that. But as for exercises, he prefers these burst workouts over cardio. As a new dad without a lot of time on his hands, are these short workouts an effective program for weight loss? I'm asking because after looking at his website I'm worried that I've only stumbled onto another fad.
Let me know if you need to know any more of the details of the program or about what I'm asking.
