Train Like a Mother Coach Jennifer Gill in her second home: the SoCal trails.

Welcome back to Move of the Month.

The Move of the Month Drill: Each month, we showcase an (interesting, helpful move from an expert Train Like a Mother Coach.

This month, we’re standing on one leg with Coach Jenn Gill, who leads the Ragnar Relay Programs and in the Train Like a Mother Club and helps for miles and miles in the Stride Programs.

A mom to three kids, Jenn is also a rockstar when it comes to knowing what your body needs to produce a strong run. She’s a personal trainer in San Diego (one of her clients just turned 100!) and practices what she preaches; her Instagram account is filled with pictures of great strength-training moves for runners.

Here, she demonstrates the One-Legged Reach, a simple but challenging move that strengthens everything from your gluteus maximus to the tiny, stabilizing ligaments in your ankle. In addition, it builds hip stability and focuses on your balance. (Can you say BOGO?)

All runners, from beginners to ultra-finishers, can benefit from adding the One-Legged Reach to their routines. (And if you’re feeling tipsy, no worries; Jenn demonstrates how to use a chair for assistance at the end of the video.)

Start with 2 sets of 8-10 reps on each side every time you strength train; the One-Legged Reach is also a great way to wake- and warm-up your body prior to a run.
