Cardio Workouts with Amanda Graydon

Here are a few high intensity cardio workouts, performed by Precision Nutrition Director of Customer and Expert Relations, Amanda Graydon.

This first workout is a simple but very difficult one. Amanda starts the treadmill at a 15% incline and 8mph. She sprints for 20 seconds and then rests for 10. Back and forth between work and rest she goes for a total of 5 minutes (or 10 total sprints). Of course, she didn’t start out at this intensity. She slowly worked up to this over time with smart progression. And every week she makes the workout harder by either increasing the speed, increasing the incline, or increasing the number of sprints she does.

This second workout is one that Amanda is famous for. She picks 5-6 exercises and does them in circuit fashion. Typically she does 30 seconds of work followed by 30 seconds of rest. Back and forth between work and rest she goes for a total of 5-6 rounds. Again, she didn’t start out at this intensity. She slowly worked up to this over time with smart progression. And every week she makes the workout harder by either increasing the work time to 35 or 40 seconds, decreasing the rest time to 20-25 seconds, increasing the load of each exercise, or by doing extra rounds of the exercises.
