First up: Cardio Kickstart
Three workouts of High-Intensity Interval Training (HIIT) a week, 20 minutes each: 4 rounds of 1 minute hard + 4 minutes of easy recovery.
What you need
A way to get your heart rate up — running, cycling, rowing, jump rope. A heart-rate tracker helps but is optional.
Why it works
Aerobic exercise and interval training are two of the largest longevity levers in the research.
