In this episode, Jared Powell is joined by Dr. Jackson Fyfe, exercise scientist and Senior Lecturer at Deakin University, to explore the science and practicality of resistance training across the lifespan.

They unpack everything from how kids can safely lift weights to how older adults can maintain muscle health and longevity. Jackson also shares insights from his research on training dosage, hypertrophy, minimal effective dose, and how resistance and aerobic exercise can (and should) coexist.

This conversation spans from myth-busting (“weights stunt growth”) to deep physiological insights about muscle as an endocrine organ. It’s a clear, evidence-based discussion that reminds us why lifting weights might just be the most underrated health intervention available.

Key topics include:

Why resistance training matters at every age

The health benefits beyond muscle and strength

How little training you can do and still get results

Strength vs hypertrophy, what actually matters?

Combining cardio and lifting: interference or synergy?

The truth about training to failure
