Workout description

Aerobic Endurance workouts are aimed at improving your efficiency at lower intensity levels.

You are training your muscles to access fat as its primary fuel source and preserve your precious glycogen stores for the finale.

After warming up, you will be completing 4 x 12-minute aerobic efforts with a 3-minute recovery.

Keep an eye on your heart rate response to the sustained power.

Are you achieving the same heart rate in the third effort as the first?.
