The 10 Minute Progress Check is a progress check of aerobic capacity (or put more simply, your ability to work consistently at moderate to high intensity for extended periods) using your 3 minute Aerobic Test to set the sub maximal level . It has the advantage of being less fatiguing than a maximal test and therefore has a shorter recovery period.
Regular progress checks are very helpful to track the effectiveness of your training plan in which improvement is usually shown by a progressively reducing heart rate for the same cadence/power output.
