About this program
Pure cardio program for trainees explicitly wanting cardiovascular adaptation without resistance training. 4 sessions per week: 2-3 Zone-2 sessions, 1 VO2max interval session, 1 stability + mobility session for fall prevention + base movement coordination.
Designed for beginners-to-intermediates wanting cardio base building. Skip this if you have any strength goals — pure cardio without lifting causes lean-mass loss per the Body Recomposition framework. Recommended only as a temporary block (8 weeks max) before transitioning to a hybrid program (Strength + Conditioning Hybrid or Longevity Three-Pillar). Equipment: bicycle, rower, or treadmill; outdoor running works.
Per the Endurance & Conditioning framework, Zone-2 (60-70% HRmax) builds the mitochondrial + cardiovascular base. VO2max intervals preserve the cardiovascular ceiling. Together they cover both ends of the aerobic spectrum. Strong differentiator if you're returning to fitness after a long break and need to rebuild cardiovascular capacity before adding lifting back in.
Honest framing: without lifting, lean mass declines per the Body Recomposition framework. Recommend 1-2× / wk maintenance lifting alongside this — but if explicitly want no-lifting, this is the program. After 8 weeks, transition to Longevity Three-Pillar (which adds heavy strength to the cardiovascular base) or Strength + Conditioning Hybrid.

Phase 1 · Accumulation
Build Base
Establish Zone-2 base. Z2 sessions extend from 30 to 45 min over 4 weeks. VO2max intervals at 6 × 4 min.
- Weeks 5–782Intensity
Phase 2 · Intensification
Build Forward
Z2 extends to 60 min. VO2max intervals progress to 7-8 hard intervals. Add long Z2 session weekend (60-90 min).

Yes. The program is the starting structure; the coach reads your e1RM trend, your weekly volume, and your effort on each lift, then tells you when to push — when a load is getting easier, it's time to add weight.
