Here’s a 1-week training plan, designed around the principles of Dr. Stacy Sims (female-specific training and hormone-aware programming) and Dr. Peter Attia (training for strength, stability, VO₂ max, and long-term health). I’ve done your homework and added instructional videos from experts in the health and fitness world including Mike Robertson, Joel Jamieson and Gerry Ramogida to eliminate the guesswork.

This plan supports women 40+ with a focus on muscle maintenance, mobility, metabolic health, and injury prevention — all key for aging optimally.

Key Principles Behind the Plan

  • Strength training 2–3x/week (Attia + Sims): Heavy lifts for preserving lean mass and power
  • Zone 2 cardio 2x/week (Attia): Low-intensity, long-duration for mitochondrial and metabolic health
  • VO₂ max / High-intensity training 1x/week (Attia): Short bursts for cardiovascular fitness
  • Plyometrics & balance (Sims): Maintains fast-twitch muscle fibers and fall prevention
  • Mobility & recovery daily (both): Joint integrity, flexibility, cortisol regulation

1-Week Longevity Training Plan

Focus: Strength, glutes, balance, and core stability


Tuesday – Zone 2 Cardio (45–60 min)

    • Repeat for 4-6 rounds (increase over time)
  • Cool down: 5–10 min easy

Focus: Cardiovascular capacity, performance aging


Saturday – Total-Body Strength & Power

Option: Add 1–2 rounds of plank or side plank

Get Morpheus to optimize your training, recovery, and results — especially if you’re focused on long-term health.


Notes for Long-Term Success:

  • Lift heavy relative to your ability — enough to feel challenged, not maxed out.
  • Track cycle phases (if still menstruating): Consider backing off intensity during late luteal phase (per Sims).
  • Prioritize sleep, protein (~1.6g/kg), and hydration.
  • Cycle VO₂ max intervals: Add more over time, not every week.

You don’t need to train harder — you need to train smarter, with intention, clarity, and confidence. Your body is capable of incredible things when you give it the right tools, the right fuel, and the right mindset. This isn’t about chasing youth — it’s about stepping into your strength, feeling energized in your own skin, and creating a future you’re excited to live in. Start today. You’re not just working out — you’re building the ageless, empowered version of yourself.
