Hi
When you do these exercises remember to begin with the other exercises from part 1 and 2 first. When trying to strengthen your knees you must begin slowly to build other areas around the knees. Do not just start with this section and skip the other sections. You may do more harm than good. Slow is good skipping steps is not good, not for knees that need work and strength. Repeat all these sections everyday and remember to do them slowly and smoothly with resistance. Fast is not good and working through the pain is not good. If you experience pain, stop do it again the next day. You will not accomplish any thing by working through the pain except making your condition worse. Drink lots of fluid and remember Rome was not built in a day and neither were your knees. You can contact me by going to www.gohealthysteps.com and click the contact button there. Enjoy.
