Hiking is a multifaceted exercise that combines moderate-intensity cardiovascular training (often in Zone 2), lower-body muscular endurance, and proprioceptive challenges from uneven terrain. Exposure to natural environments ('green exercise') also provides significant psychological benefits, including stress reduction via lower cortisol. These combined effects improve cardiorespiratory fitness, metabolic health, bone density, and mental well-being, all critical components of healthspan.
Verdict
A foundational, low-cost intervention for comprehensive physical and mental healthspan.

Protocol
- Engage in 1-3 sessions per week, each lasting 60-180 minutes on varied terrain.
- Incorporate significant elevation changes to increase cardiovascular demand and muscular engagement.
- For added resistance and bone density benefits, consider carrying a weighted pack (rucking).
Flags
- Risk of falls and joint strain is elevated on uneven or steep terrain.
- Proper footwear is critical to prevent acute and chronic injury.
- Requires access to suitable trails or natural environments.
- Dehydration and sun exposure are key environmental risks to manage.
