Powerlifting with all the gimmicks they use to lift is just nonsense. I saw a powerlifting friend in the gym who is about 5'6" and 180lbs tell me he can bench 405lbs. He first put on his power lifting shirts that looked like a straight jacket. He bent his body into an inverted V. He took a deep breath. His range of motion was just about nothing. His elbow joint barely bent at the lowest point. Just nonsense. He can't do more push ups than me. Using a hammer strength bench where he can't cut the range of motion he can't do 4-45lbs a side on the machine because he can't budge the weight from the starting point.
Low half squat that power lifters are calling a full squat with a suit is also bs. I watch these guys "squatting" 650 plus and they don't have enough power in their legs to touch the rim of a basketball rim. What good is the "power" they are developing?
The sumo deadlift is used so they can cut the range of motion.
The real sport of strength is Olympic lifting. Pick up a bar from the floor and put it over head. No gimmicks. You need strength and power to complete the lift. Any football player who starts doing power cleans can back me up that they saw an immediate gain in jumping and sprinting ability. When an Olympic lifter squats they bury it. They don't do a hip lock as Mike Bridges use to call squats.
