When I do lunges or when I run, when I have one leg in front I cannot get back into a standing position. I have actually fallen down running because I couldn't get my leg to straighten up to move my other leg forward. It's really hard to explain. I do a lot of biking and have no problems with that. I can do squats with no trouble. I know I need to strengthen certain muscles. When I was going to a gym the trainer was explaining how the wrong muscles were trying to do the job and the muscles that should be doing it were weak.
My questions are:
- How can I strengthen the correct muscles when other muscles keep taking over?
- How do I get back to a standing position when lunging or running?
