And that is where I slip up! As someone who constantly looks at the micro vs macro, my head gets stuck with - which workout helps to get me to the larger goal of the plan. I would think that spending longer time at threshold would assist in building muscular endurance and raising threshold power (more than sweet spot), but I feel that could be a narrow way of looking at it due to my relatively new introduction to this type of training.
Choosing to move to mid volume was definitely the best choice for my training, but this factor was just something I hadn’t planned when moving from low to mid!
