Watch Troy Polamalu work out ((NEW AGE))

Troy Polamalu might look like he can bench press a Buick, but the Pittsburgh Steeler does not touch a heavy barbell when he’s preparing for the NFL season. Removing himself from the regular training camp, the six-time Pro Bowler works out at the Sports Lab in California where he undergoes an intense regiment of workouts known as iso-kinetics. Focused on building faster muscles instead of bigger ones, the exercises put an emphasis on balance and quickness in an attempt to literally change the nerve system of the body. So instead of clean-and-jerks, Polamalu will do light squats while balanced on a BOSU ball. The idea is that the safety’s muscles will react so quickly that his hits will be more explosive. The highlight reels speak for themselves.
