Chipmunks are so super energetic that they need to, on average, eat 20% of their bodyweight, each day just to survive. This leads us to the explanation of why Chipmunk is the kind of workout that will have you landing squarely in the sweat zone from the very first set. This is a great workout for improving your aerobic capacity and your VO2 max performance.
Extra Credit: 1 minute rest between sets.
