I just finished six straight weeks of clay court events. You have to be fit for the clay. I was in two semi-finals and one final. Not bad for the oldest competitive singles player on tour who had a career ending back injury at 29. I am off to the grass in England and your drills from Concrete Conflict have made my recovery time and fitness level amazing. Keep bringing me the good stuff!
