Episode notes
Use Intermittent Fasting Strategically Around Training
- Try intermittent fasting as time-restricted eating to reduce total calories without cutting food groups.
- Use it strategically: fasted training works for <1.5–2 hours of exercise, but long sessions need pre-fuel to avoid bonking.
Strength Train Three Times A Week For Longevity
- Do strength train at least two to three times per week for longevity and healthspan, with 45–60 minute sessions.
- You can get excellent results with 2.5–3 hours of weekly strength work plus short cardio sessions.
Let Recovery Dictate Your Workout Schedule
- Do follow a workout split you enjoy but detach it from strict weekly scheduling; let recovery dictate timing.
- Justin uses a six-day push/pull/legs split that can stretch to 8–14 days depending on pickleball load and recovery metrics.
