Some common mistakes that powerlifters make include not warming up properly, using improper form, not allowing for enough recovery time, and not adjusting their program as needed.

To prevent injuries, a powerlifter should focus on proper form, warming up properly, and including exercises that target the major muscle groups used in powerlifting. Additionally, a powerlifter should listen to their body and take rest days as needed to allow for adequate recovery.

A beginner powerlifter should start with a basic program that focuses on the three main powerlifting exercises: squat, deadlift, and bench press. The program should also include accessory exercises to target the major muscle groups used in powerlifting.
