Bullmastiff gives each phase more room to build
Its two nine-week phases suit lifters who want volume to accumulate before a longer intensification and peak.
Juggernaut makes the wave changes explicit
The 10s, 8s, 5s, and 3s waves make the shift from volume to intensity easy to see and plan.
Both require deliberate fatigue management
AMRAP work and manual training-max updates mean recovery and honest performance tracking matter more than automatic load jumps.
