It was my experience that the first three months, I was sore to the point of finding daily routine activity painful! lol! I just remember trying to figure out how to get up and down my steps without bending my legs.
After three months passed, and now going on two years later, I still get sore, but nowhere near like it was those first three months -- it's sore, but not debilitating sore. So, stick it out - and it will get better!
