Fitness, military style

From pull-ups, to sit-ups, to heaving tractor tires end over end, this is a fitness routine for the really dedicated. CrossFit was originally designed as a workout military, police, champion martial artists and others who required serious strength conditioning. The program is moving into gyms and is available for the average Joe now.

There are no shiny, fancy machines required for this workout. All that's needed is a mat for floor exercise, a climbing rope, jump ropes, various weights, and a few other key ingredients. The workouts are short -- only 10 to 20 minutes -- but they're intense. There's no rest between exercises, it's move-move-move from station to station. You'll work your abs, arms, shoulders, legs, glutes... basically you'll work everything! Even though it's an "elite" fitness program, anyone can join. The instructor will assess your fitness level and determine the exercises that are best for you. Prepare to be challenged -- and be all that you can be!
