Uneven quads

hi lee! i wish you had a clone in japan so i can take lessons here 😉 i have this small question about uneven quad muscle use; my left quad muscle is bigger/stronger than the one on the right.

sprint, standup and coast > i find myself resting on my back foot (left leg). interestingly, my right foot is the forward foot but my power stroke consequently becomes my left foot.

split squats in order?

thank you!


Right foot forward through a right turn. I prefer to lead with my left foot, but the more I practice this the more normal it feels — and the more I find myself switching lead feet on trail.

Hey Niño!

Most riders lead with their left leg and drive their power stroke with their right leg. This is considered “normal” and right-leg dominant.

You sounds like you are “goofy,” and that you are left-leg dominant. This is nothing to worry about:

• None of us are perfectly balanced side to side. Our dominant sides are always bigger, stronger and smarter. Heck, I swear my left leg is dumb sometimes. And my left arm? Puny. The shattered shoulder joint does not help.

• Ideally, all Riders (capital R) will learn to lead and power with either foot. Not only does this lead to better lateral balance, it also makes you a much more rounded, adaptable rider. Start practicing today. If you have a pump track, alternate directions and lead legs. If you’re turning left, lead with your left leg.

• When you do your off-bike mobility/stability/strength work, focus on single-sided exercises — and focus on your dumb side.

I have been studying with master trainer Erin Carson at RallySport Health and Fitness in Boulder, CO. Thanks to Erin’s tutelage, my current favorite exercises include:

• Multiplanar lunge warmup
• Cable lunge to press
• Cable hinge to row
• Reverse lunge

Most single-leg exercises will help you, as long as you’re consistent and use safe technique. You’re a mountain biker: Don’t hurt yourself in the gym!

Have fun out there!
