Exercise isn't rocket science, but it is based on science, and thinking you know more about training than you do is a conceit that can doom you to years of stagnation—not to mention injuries. You don't need a personal trainer; Men's Fitness and mensfitness.com are full of workouts from the best trainers in the world. Whatever workout you choose, just be sure to stick with it for four weeks.
