Jackson Fyfe - Exercise Science Lecturer - Wants To Persuade The Public To Exercise.

2026-02-12

Today I chatted with Jackson Fyfe - Senior Lecturer, Strength and Conditioning Sciences, Deakin Uni Melbourne.

He's a thoughtful practitioner of translating exercise science for the general public and a lovely bloke, to boot.

We chatted about:

1/ Why do we find it so challenging to exercise?

2/ Is there even such a thing as "optimal" exercise?

3/ Why exercise and movement doesn't need to be rigid or complicated to impart a big benefit.

4/ Do tradies need to do structured training, too? Even if their jobs are really physical?

5/ How much of a difference can it make in your life for you to exercise?

6/ Why chasing "optimal", as opposed to what feels good for you, can be a dead end.

7/ Is the point of exercise science research to help people exercise (implementation science)? Or to uncover new knowledge (basic science)?

8/ Some cool physiology stuff:

the systemic benefits of exercise myokines

9/ Why do GPs reach to the subscription pad so readily?

10/ Why people over 50 should lift weights
