Building the engine - recently I have been alternating between High Intensity Sprints and Longer Easier Pace Cardio on the AD8.
Due to time constraints this was somewhere in the middle, and absolutely rinsed me. Previous PB for 500 kcal was around 27/28 minutes.
Looking for something a bit different with your training today? Set the timer for 500 kcals and push hard.
Tag me in your efforts below.
