A lot of wisdom (mainly MDA but also others) recommends sprinting once per week. This confuses me a little.
- My understanding is that our bodies recover and repair much faster than that.
- I can't imagine our ancestors only hunting once a week (this does assume, as seems to be the dominant approach to paleo and sprinting justification, that hunting is the main reason/back-story to our need to sprint...this is not meant to re-open old debates on that point)
So why once a week sprints? What's the mechanism behind the "Less is more" approach to sprinting?
