Okay, I cannot figure how to do any type of forward lunge without some serious bad feelings in the leading knee. I CAN do step-ups pain free. So, two questions:
1) What is the purpose of the lunge? Is it to work certain muscles, or is it mainly to challenge ones balance? If I knew what the purpose was, maybe I could come up with some alternates myself.
2) Not really a question, but any suggestions for alternates or baby-steps for the lunge impaired would be appreciated. Thanks!
