Episode notes
Assess Before You Program
- Test current capability before programming so your plan matches reality.
- Use simple assessments (one-mile, VO2/Cooper) to guide priorities and constraints.
Use Validated VO2 Surrogates
- Use VO2 tests (Cooper run or Concept2 2K) to estimate aerobic engine size.
- Compare results to population data to choose targeted interventions.
Check Anaerobic Capacity With Short All‑Outs
- Assess anaerobic/lactate capacity with short all-outs (30s, 60s, 180s) on a rower or running 200/400m splits.
- Use RPE or simple split drop-off to decide lactate-specific work.
