I have been exercising for many years. Of late I’m experiencing some pain in my knees. It’s not continuous – i.e., it comes and goes. My coach introduced step ups and traveling lunges to my leg workout recently. This is in addition to squat, curl and leg extension. The step is about 20 inches high, and I’m doing the exercise without weights. The traveling lunges I’m doing with a short thick bar. The other new thing I’ve lately taken up is twicea-week salsa classes. Could these activities be causing the pain? Should I be concerned? What should I do to avoid exacerbating the problem? Overall otherwise I’m pretty fit. Please clarify.
