Where people go wrong

  • Treating the formula as your true max.
  • Doing every session in Z4/Z5.
  • Ignoring medication, illness or heat effects.

FAQ

Is 220 minus age accurate?

It is a population average; individuals can differ by 10-20bpm. A field test is better.

What is Z2?

Easy aerobic work where you can talk; builds base and aids recovery.

Can I use it with heart disease?

Ask a doctor first; do not use this instead of medical advice.
