I was talking to a ride buddy who's a really good climber and he suggested I add in a some good quad exercises 3 times a week. I started my routine yesterday from home by doing a lot of squats / lunges with various weights and today my left leg is in horrible pain although my right is almost not sore at all. I always figured while riding I was putting out equal power on both legs, but based on my soreness left leg is pretty week by comparison.

Is there any techniques or things to focus on while riding to get the left leg up to the same strength as the right leg? I have a feeling I'm relying on my right leg a lot more during my rides and not even realizing it.
