«Program for the best, scale for the rest»
All workouts are made to produce a certain stimulus. That creates a problem when you present a «one size fits all» workout. The solution to the problem is …… scaling.
If all the «Rx super fit people» use 10-15 minutes. Your goal should be to use about the same.
If the time cap is set to 20 minutes and you still don’t make it, it’s total scaling disaster 🤪
