What is enough when it comes to taking care of ourselves? We’re told that walking three times a week is enough, but is it? What is an optimal level of activity? David breaks through the low bar set for people in later life, and shares what he does to stay fit at 62 from HIIT to weightlifting to intermittent fasting. While his regime isn’t for everyone, we can all do more than we think. David explores the path to building fitness whatever the starting point, and answers reader questions on sleep, retirement, and blue light.

Say hi to the AGEIST team!
