2 years ago, when i was coaching gymnastics, We had an olympic judge come in and help evaluate our team, so my boys asked me to do a routine for the judge to see how "coach" would do. I beat all my boys on floor and the judge told me that he was shocked someone 40 years old could still tumble like I could. He gave me a 9.65 which was .20 better than any of the teenagers. # months later I tore my rotator cuff and haven't really tumbled since, but I'm almost ready to start up again!!
