The brief
What this block builds
- Late-round cardio so your output never drops.
- Focus: Engine · cardio.
- Most fights are lost to the gas tank, not the chin. Fix it here.
How the book works
- Ten pages. Four training weeks. One test.
- Every session runs itself with the built-in round timer — phone in your pocket, bell in your ears.
- Baseline: 5 rounds of the session on the next page, as a circuit.
