8 sprints once a week outperforms 45 minutes of steady state jogging for body composition and hormonal output. Every time.
Here is why.
10 seconds of all-out sprinting:
✅ Recruits Type IIx fast twitch fibers
✅ Triggers a significant GH pulse
✅ Produces EPOC — elevated fat oxidation for up to 24 hours
8-10 sprints once a week. That is the entire protocol.
