Mabye bulk was not the right word, but Tiger has added a lot of muscle. I have seen Tiger in person, and I did not think he looked normal. I thought he looked extremely strong fit much like a wide receiver. I just wonder if he is as obsessive about his work out as his golf swing. I wonder if fine tuning becomes over tuning. Also, I lived near Ft. Bragg, and I never saw anyone running in combat boots. All the pt I saw was in running shoes.
