Do you have any nagging injuries? If you suffer from wrist pain, tennis elbow, shoulder pain, lower back pain, knee pain, plantar fasciitis, or anything similar, then I want to invite you to pick up a copy of "Tennis Over 40," because inside Dr. Mark Kovacs will make small adjustments to how you play so you can reduce and prevent wear and tear on your body. These small adjustments can be as simple as your stance when you hit your forehand (the wrong stance is one of the leading causes of knee pain). This program isn't about blowing up your strokes. Instead, it's about making a few small adjustments to take stress off your body, off your joints, so that you can play pain free.
