Book excerpt: Knee Ability Zero is not a medical book, rather: it is a step-by-step manual which allows you to find and improve your pain-free ability, and this has resulted in over 2000 knee success stories for people of all ages and walks of life.Over 8 steps we build "from the ground up" - from your ankles to lower legs to knees to thighs to hips, improving the strength, control, and freedom you have over your body, with explanation of why each step helps your knees. The 8 steps take 15-20 minutes in total, and I suggest doing them up to 3 times per week.You do not need any weights, equipment, or special abilities for this program, and you can start applying Step 1 from the moment you open up the book!
