I've done a comparison of the major exercise categories (HIIT, Aerobic, Strength Training, and walking) to see how much life extension each can provide, and then quantify the return on time invested for each.
Highlights:
- Both HIIT (including aerobic exercise) and walking can provide an additional 10 years of life if started from about 40 years old
- Strength Training provides an additional 2 years
- For pay-off on time invested, nothing comes close to doing HIIT, with over a hundred times extended life for the time put in. Doing HIIT once a week for 20 minutes each week give two days of average lifespan.
