Ok, day 1 of “Afterburn” is in the books. I’m not sure what to call it really. In NROL, the author calls it “Metabolic Overdrive.” Cosgrove calls it “Afterburn” though so I’m going to stick with that.
This is a 16 week plan.
For the next 4 weeks I do 3 “rounds” 3 times a week. A round is a minute sprint followed by a two minute jog.
Week’s 5-8 will be 4 rounds 4 times a week.
Weeks 9-12 will be 5 rounds 4 times a week
Weeks 12-16 will be 6 rounds 5 times a week.
Today I ran at 8.5 and jogged at 6.0 on the treadmill. It’s pretty tough toward the end but mostly it was a breeze. I was definitely sweating, though! The worst part was the downshift from sprinting to jogging. It almost made my legs feel more tired. Weird.
I’m going to try to up my sprint to 9.0 next time. I hope the treadmill can handle it! I was kind of nervous running as fast as I did.
