Thanks for your answer !
It makes sense. But after reading deeply the book, and listening to many podcasts, I can not really see a difference in terms of what we are targeting when we are doing Hill sprints, ME workout indoor, ME workout outdoor.
My understanding is : Hill sprints work best to raise your ceiling, improve strength and power. Then, when you raised you ceiling, you can better improve your Muscle endurance by working on strength endurance. Is it right ?
Gareth Standford’s work is very interesting on the topic and he is speaking a lot about this “logic” of raising the ceiling first, and keep it elevated year around.
