Exercise, graded.

Movement is the closest thing medicine has to a longevity drug. The entries below grade specific training habits, from brisk walking to balance work, against trials and cohort data rather than gym-floor folklore.

The short version: 3 of the 11 patterns below grade Strong — Zone 2 cardio, Resistance training, Balance training; 5 are Moderate — defensible, but for the right person; 3 grade Weak — thin proof, still widely sold.

Grade

Strong evidence

Randomised trials or very large, consistent cohorts tie this to outcomes people care about: heart attacks, deaths, fractures. Guideline bodies recommend it.

01 Zone 2 cardio Zone 2 is the current name for brisk, conversational, moderate-intensity cardio done steadily. Strong 02 Resistance training Lift something heavy twice a week. Strong 03 Balance training Falls are the injury many people past 60 never see coming, and much of the risk responds to training. Strong

Grade

Moderate evidence

A real signal with honest limits: consistent associations, or trial endpoints that stop short of outcomes. Reasonable to adopt; do not expect miracles.

04 High-intensity interval training (HIIT) Short bursts of hard effort separated by easy recovery: 30 seconds to 4 minutes hard, repeat. Moderate 05 Daily step count Walking more is the least glamorous intervention on this page and one of the most dependable. Moderate 06 Walking after meals You do not need a gym. Moderate 07 Cycling to work Riding to work turns travel time into training time. Moderate 08 Exercise for brain health Movement shows up again and again when researchers compare people who keep their thinking skills with people who lose them. Moderate

Grade

Weak evidence

The measured benefits are small, indirect or unproven. Fine because you enjoy it; not something to schedule your life or budget around.

09 Stretching & mobility work Few things feel as virtuous as a good stretch session. Weak 10 Swimming If sore knees have ruled out running, the pool deserves a look. Weak 11 Yoga Yoga plays a supporting role here. Weak

How to read these grades. They use the same four-step scale as our test reviews, and they answer a different question: whether doing this is worth your time and money, judged on the published evidence in people. A weak grade means the proof is thin, never that we found proof of harm. Read the methodology.
