Movement that lasts
Fitness
Muscle is the organ of longevity, endurance the engine. Here is how much of each you need and how it fits into a full life.

The organ of longevity
Strength training after 40: the plan that brings muscle, bone and years
From 40 the body loses muscle every year unless someone objects.

At talking pace
Zone 2 training: the slow endurance that extends life
Zone 2 is the pace at which you can still speak in sentences.

Moving through the full range
Mobility: flexibility that keeps joints young
Stiff hips, shortened hip flexors, a back that will not cooperate in the morning: flexibility vanishes unnoticed.

The 10,000 question
Steps per day: how many are enough and how to collect them
10,000 steps come from a Japanese advertising campaign, not from research.

Oxygen as a measure
Raising VO2 max: the strongest fitness marker for a long life
Maximum oxygen uptake predicts life expectancy better than smoking, diabetes or high blood pressure.
Training
Heart Rate Zones
Age and resting pulse: your maximum heart rate and the five training zones after Karvonen, with zone 2 as the fat-burning range.
Your personal longevity plan
How old is your body, really?
