Here are several quick ways to check which is your dominant leg.
Looking through the recent Question of the Week had me thinking of a quick way to determine which of your legs is dominant.
During bike fitting, I need to know this as a possible reason for pains in their lower body due to irregular pedaling (caused by muscle imbalance).
Figuring it out requires some detective work since, for example, let’s assume someone has right leg dominance.
Sometimes their right leg hurts due to the right leg doing 60% or more of the work while the weaker, non-dominant left leg does less than 40%.
But sometimes their left leg hurts in this situation, due to the left leg trying to stay up with their right leg.
This is where an experienced bike fitter or physical therapist can help solve this problem.
Here are some simple tests:
A. Push back
- Have the person getting tested stand facing you.
- Lightly push on their forehead.
- Continue pushing until they take a step back.
- The leg they step back with will be their dominant (and stronger) leg
B. Skateboard or Surfing
- Which leg is behind when you skateboard or surf. That should be the dominant leg.
C. At a stop sign
- Which leg do you support yourself with when you unclip and put your foot down. That will be the dominant leg.
Hopefully one of these methods will help you figure it out if you don’t know already.

Your B and C tests are not reliable. I surf, and snowboard, regular foot and skateboard goofy foot. My wife snowboards goofy and surfs regular. I don’t always put the same foot down when I stop. I was just noticing on my ride today that the foot I use at a stop varies as circumstances dictate. Example: if there’s a right turn lane on my right then I put my left foot down to lean away from any cars that want to turn or of there’s a curb on my right then I may put my right foot on the curb for an easier reach.
I put my goofy foot down at stops because my good foot has more power to the pedal to restart. When I swing my leg off, it’s always the good foot (but that’s also swinging off to the non-chain side of the bike – do we all do that?)
Not a surfer, skateboarder, or snowboarder so I will leave it to others to comment there, but the “which leg down” test is definitely not reliable. I put my left leg down to keep from getting a chainring tattoo on my right leg. It has nothing to do with my left leg being dominant (I am definitely right leg dominant). It’s simply something I have trained myself to do over decades of riding.
