It works for her clients and it reads like a who’s who in the endurance world. I’ve never done the blood work to know, and won’t, but it works for me a well.
She has some great podcast interviews on it and her stuff is easy to find online under the ‘EC Fit’ banner. I really like her programming a lot and it’s made me more resilient and ultimately faster because I can train harder without all the nagging pains / aches.
I hate dropping her name in this thread, but the talk about hormonal changes / response ties into it. Instead of manipulating it via supplements, you’re doing it through weight training that is timed around certain endurance workouts.
Obviously weight training has its place for strength work too, but that’s programmed a little differently.
