Biomechanist Katy Bowman and biologist Jeannette Loram take a deeper look into three recent headlines in the body-nerd world.

First up, recent research has shown that our skeletal muscles remember training at the protein level - no brain required! This is exciting research and Katy and Jeannette discuss the implications for exercise over the lifespan. Second, they dig into a recent study of uphill walking; the research suggests it is cheaper to take the steeper route, but energy efficiency might not be the only consideration. Finally in response to the online noise about recent changes to the CDC developmental guidelines, Katy and Jeannette explain what has really changed and whether it should have caused such an upset.

Biomechanist Katy Bowman and biologist Jeannette Loram continue their discussion about the skeleton. In this episode, they break down the best approach to taking care of your bones using a government framework: Strong, Steady and Straight. They use this framework to discuss exercise and bone loading at three life-stages: a growing skeleton, a mature skeleton and a vulnerable skeleton. Listen to this episode to design a movement plan for your bones.

Also in this episode, Katy talks to Mike Dally, founder of Earth Runners, minimalist earthing sandals. Katy has walked more miles in Earth Runners than in any other shoe and Katy and Mike talk about her favourite features; from the non-slip foot bed to the replaceable straps and laces. Mike explains earthing technology and testing and describes their latest product that can ground any minimal shoe.

This is the first of two episodes on bone. There is lots of discussion in the media about bone health and in this first episode biomechanist Katy Bowman and biologist Jeannette Loram place bone tissue health into a wider context; what really matters is how well the entire skeleton is working—as a system—to support our bodies and our movement.

Katy and Jeannette explain how the status of the bone in different parts of your skeleton is a record of the movement you have—and have not done—in the past. They outline Wolff's law, the idea that bone adapts and changes according to the stress and load it experiences throughout a lifetime. They bring this concept to life using examples from populations with distinct movement and bone loading histories ranging from ancient human archers and farmers, through different sporting populations to astronauts.
