Movement & Training: The Centenarian Decathlon Framework

4:00 PM - 6:00 PM

💪4:00 PM

Muscle is longevity. Preserve it with intention, or lose it by default.

Strength Training: Progressive Resistance & Muscle Preservation

Peter's strength training follows a 3-4 day per week upper/lower split with 30-45 minute sessions. He performs 10-15 total sets per muscle group spread across 2-4 sessions, using 6-15 rep ranges depending on training phase. Each set is performed 1-2 reps from muscular failure to maximize hypertrophy and strength. Exercises include squats, deadlifts, bench press, rows, and isolation work.

Strength Training Protocol

3-4 days per week structured strength training (upper/lower split)
30-45 minute sessions with 10-15 total sets per muscle group
Rep ranges: 6-15 reps depending on phase (strength vs. hypertrophy)
Training intensity: 1-2 reps from muscular failure per set
Compound movements prioritized: squats, deadlifts, bench press, rows, overhead press

"Strength training is the most powerful longevity tool available. It's non-negotiable."

Everyday adaptation: Start with 3 compound movements twice per week: squats, bench press, and rows. Use bodyweight or dumbbells. Perform 3 sets of 8-12 reps, stopping 1-2 reps short of failure. This takes 30 minutes and preserves muscle for life.

🚴4:45 PM

Zone 2 is where longevity lives. It's not sexy, but it's essential.

Zone 2 Aerobic Training: Mitochondrial Efficiency & Endurance

Peter performs Zone 2 aerobic training 4 days per week for 30-60 minutes per session. Zone 2 is defined as 60-70% max heart rate or 2 mmol/L lactate threshold—a pace where he can hold a conversation but feels challenged. Activities include cycling, running, rowing, or hiking. This training builds mitochondrial density, improves fat oxidation, and enhances aerobic capacity without the recovery cost of high-intensity work.

Zone 2 Aerobic Protocol

4 days per week Zone 2 aerobic training
Duration: 30-60 minutes per session at 60-70% max heart rate
Activities: cycling, running, rowing, hiking, or swimming
Intensity: conversational pace—you can speak but not sing
Use VO2max Testing and Lactate Analysis to calibrate Zone 2 boundaries

"Zone 2 training is the foundation of aerobic fitness. Build it first, then add intensity."

Everyday adaptation: Go for a 30-minute walk or easy bike ride at a conversational pace 3-4 times per week. No equipment needed. This single habit improves heart health, mitochondrial function, and longevity markers.

🧘5:30 PM

Stability is the prerequisite for strength. Master it before you load it.

Stability & Balance Training: Injury Prevention & Functional Movement

Peter dedicates 2-3 sessions per week to stability training, including single-leg balance work, core stabilization, and proprioceptive exercises. Sessions last 15-20 minutes and include exercises like single-leg deadlifts, balance board work, and anti-rotation core drills. This training is performed before heavy strength work to activate stabilizer muscles and reduce injury risk. He uses Biodex Balance testing to assess and track stability improvements.

Stability Training Protocol

2-3 sessions per week dedicated stability training
Duration: 15-20 minutes performed before heavy strength work
Exercises: single-leg balance holds, single-leg deadlifts, balance board work, anti-rotation core drills
Proprioceptive focus: eyes open and closed, unstable surfaces
Use Movement Screening protocols to identify weak links

"A strong body with poor stability is an injury waiting to happen. Invest in the foundation."

Everyday adaptation: Perform single-leg balance holds for 30 seconds per leg, 3 times per week. Add single-leg deadlifts with light dumbbells. This 10-minute routine prevents falls and injuries while building functional strength.

⚡5:50 PM

High-intensity training is the most time-efficient way to build aerobic capacity. Use it strategically.

Anaerobic Power Training: VO2max & Lactate Threshold Work

Peter performs 1-2 high-intensity anaerobic sessions per week lasting 20-30 minutes total (including warm-up and cool-down). These sessions include VO2max intervals (4-8 minutes at 85-95% max heart rate) and lactate threshold work (8-12 minutes at 75-85% max heart rate). Activities include cycling, rowing, or running. Recovery between intervals is 2-3 minutes at easy pace. He uses Lactate Analysis and VO2max Testing to calibrate intensity.

Anaerobic Power Protocol

1-2 sessions per week high-intensity anaerobic training
Total duration: 20-30 minutes (including warm-up and cool-down)
VO2max intervals: 4-8 minutes at 85-95% max heart rate
Lactate threshold work: 8-12 minutes at 75-85% max heart rate
Recovery: 2-3 minutes easy pace between intervals

"VO2max is one of the strongest predictors of longevity. Protect it with high-intensity training."

Everyday adaptation: Once per week, do 5 minutes of hard cycling or running (8-9/10 effort), then 2 minutes easy. Repeat 3-4 times. This 20-minute session builds aerobic capacity without requiring a gym.

🎒6:00 PM

Rucking is the most underrated training tool. It's functional, sustainable, and builds real-world strength.

Rucking: Loaded Walking for Strength & Endurance

Peter performs rucking 1-2 times per week for 30-60 minutes with a weighted backpack carrying 10-20kg (22-44 lbs). Rucking combines strength and aerobic training while building practical, functional capacity. Pace is moderate (conversational), and terrain varies (hills, flat, trails). This training is low-impact, sustainable long-term, and builds resilience for real-world demands like carrying groceries or traveling with luggage.

Rucking Protocol

1-2 sessions per week rucking with weighted backpack
Duration: 30-60 minutes at conversational pace
Load: 10-20kg (22-44 lbs) depending on fitness level
Terrain: vary between flat, hills, and trails for adaptability
Real-world functional benefit: builds practical strength for daily demands

"Rucking is training for life. It builds strength, endurance, and resilience in one simple practice."

Everyday adaptation: Fill a backpack with books or water bottles (10-15 lbs) and walk for 30 minutes at a comfortable pace. This costs nothing and builds functional strength while improving cardiovascular health.

Workout FAQ

The Centenarian Decathlon is Peter Attia's framework for longevity-focused fitness, comprising five pillars: strength training, Zone 2 aerobic capacity, stability and balance, anaerobic power (VO2max), and rucking (loaded walking). This framework is designed to build the physical capacities needed for a vibrant final decade of life. Rather than chasing arbitrary fitness metrics, the Centenarian Decathlon focuses on functional, real-world capabilities: the ability to carry groceries, recover from falls, maintain muscle mass, and sustain aerobic fitness. Peter structures his entire training week around these five pillars, dedicating specific days to each modality. Strength training 3-4 days per week preserves muscle mass and bone density. Zone 2 aerobic training 4 days per week builds mitochondrial efficiency and cardiovascular health. Stability training 2-3 times weekly prevents injury and maintains functional movement. Anaerobic power training 1-2 times per week improves VO2max and lactate threshold. Rucking 1-2 times weekly builds practical, functional strength. This multi-pillar approach ensures balanced development across all dimensions of fitness, rather than overspecializing in one area. The beauty of the Centenarian Decathlon is that it's scalable: beginners can start with lighter loads and shorter durations, while advanced athletes can increase intensity. The framework is grounded in longevity research showing that these five capacities are the strongest predictors of healthspan (years of healthy life) and lifespan.
