One leg more muscular than other

[Earthwormjim]

Started commuting to work (30 mile round trip) a couple of months ago and have noticed a big difference in my legs but one seems to be a good bit bigger than the other. Is this normal or should I be working the other leg more?

Do you have clipless pedals and always unclip one side (pushing off with t'other)? FWIW, I would think it's normal to have 1 that's a bit bigger than the other. Obviously if it's twice the size then something isn't normal...

Maybe less so with my legs but one arm is deffo bigger than the other, my right being larger and no, it's not because I'm a right (handed) w*nker

I thought this a while back, my right leg is not bigger but more toned.
