To deliver the results of a 60 minute workout in just 25-minutes, Shaun uses Focus Interval Training (FIT). He takes on one muscle group at a time, works it to exhaustion and when you can’t do even one more rep, he moves on to the next muscle group…and then the next. From glutes to shoulders, abs to quads, biceps to obliques. Get the picture? It's a 25-minute, full-out attack on your body, without any rest. The only thing it leaves time for is scorching fat and sculpting muscle.
