Live longer, feel better, what's actually solid
Novice
Subdomain
Regular movement and resistance training are the single biggest levers for healthspan. Muscle and aerobic capacity protect almost every system you care about.
Zone 2 cardio
Sustained aerobic exercise at an intensity where you can still hold a conversation but not sing, targeting roughly 60 to 70 percent of max heart rate.
Open
NEAT, non exercise activity
The energy you burn through all daily movement that is not formal exercise, walking, fidgeting, standing, climbing stairs, housework, commuting.
Open
Sarcopenia
Age related loss of skeletal muscle mass and strength, accelerating after the 40s and a primary driver of frailty, falls, and mortality in later life.
Open
Resting heart rate
The number of times the heart beats per minute when fully at rest, a basic marker of cardiovascular fitness and autonomic balance.
Open
Strength training fundamentals (compound lifts)
A foundational approach to building strength that centres on multi joint compound movements: squat, hinge, push, pull, and carry patterns loaded progressively.
Open
Yoga and India context (asana types)
An ancient Indian discipline integrating physical postures (asana), breath (pranayama), and meditation, with growing modern evidence for cardiometabolic and mental health benefits.
Open
VO₂max
Max rate of oxygen use, a key measure of cardio fitness.
Sarcopenia
Age-related loss of muscle mass and strength.
Healthspan
Years lived in good health, not just total years alive.
Ultra-processed food
Food heavily transformed with industrial ingredients (Nova classification).
Chronic stress
Persistent activation of the stress response, damages multiple systems.
Relative risk
Risk in one group vs another, sounds bigger than absolute risk.
Absolute risk
Actual probability of an event in a population.
Meta-analysis
Statistical combination of many studies, usually more reliable than any one.
HRV
Heart rate variability, beat to beat variation, a proxy for recovery and stress.
NEAT
Non exercise activity thermogenesis, calories burned through daily movement outside workouts.
Zone 2
Steady aerobic effort where you can still talk, builds mitochondrial fitness.
