Having coached many competitive powerlifters for the last 3-4 years, I've noticed common areas in the realm of training and recovery that many strength athletes neglect. Either the importance of these areas have not been stressed enough by their coaches and the environment they lift in, or the athletes fail to see the impact it plays on their powerlifting performance.
Powerlifting is unique in that it revolves around performing lifts that would be otherwise used as a form of physical preparation in other sports. The squat, bench press and deadlift are all lifts that are commonly used in sports like football and hockey to increase upper body and lower body strength. As a powerlifter though, your success depends on your strength on these big 3 exercises.
