Drew Brees is a natural athlete, but these days, it takes a lot more than natural ability to play football in the NFL, much less to be named the Super Bowl MVP. The New Orleans Saints quarterback told the Wall Street Journal that his workout focuses on improving three key areas: balance, core strength and joint integrity in order to reduce risk of injury. To prepare for football season, Brees works out three hours a day, five days a week with strength-and-conditioning coach Todd Durkin. They may focus on speed one day and then on strength or power on another. Brees trains with a lot of different equipment to ensure hes working multiple muscle groups, including medicine balls, stability balls and even tires. He also works out almost every day with this nylon-strap suspension system called the TRX. The TRX, which happens to be one of my favorite training tools, was created by a Navy SEAL for training in small spaces like ships and submarines. Rather than using weights, TRX pits your body weight against gravity, which makes for some really fun and very effective training sessions. TRX classes are now being offered at a lot of gyms, but if you want to try a move from Drew Breess workout on your own, start with the most basic - the suspended crunch. Heres how to do it: First, attach the straps to an overhead bar. You want the ends to be about 8 inches off the ground. Put your feet in the straps and get into pushup position. From here, lift your hips and pull your knees in toward your chest, and then straighten your legs back out to the starting position. That's one rep. Do 2 sets of 15 reps to help strengthen your core and shoulders. To find out how more celebrities stay in great shape, check out other videos in this series.
