A powerlifting routine is primarily focused on improving strength in three main lifts: bench press, squat, and deadlift. The goal is to increase the maximum amount of weight lifted in these compound movements. Training usually involves structured programs that emphasize progressive overload, allowing lifters to gradually increase weight or volume for continuous strength gains. Powerlifting also requires proper technique and form to prevent injuries. Competitions are based on the heaviest successful lifts in these three categories, showcasing the lifter's overall strength and dedication to the sport.
