The Deadlift and Squat are both sections of Olympic Lifts .... you need to be coached .... no one here mentioned getting organized before a lift , in fact from some descriptions I assume they went in to the lift totally out of position , and instead of generating torque , they just dumped the lot and while on that subject , absolutely no mention of generating torque ??... To get the full benefit from these lifts you need to learn how to do them correctly .. and for that you seriously need a coach ........ it's not just bend over and pick it up or squat down and stand up again ... learning to do them correctly will set you up for improvement across the board .... then throw in shoulder pressing and you have the skills you need to put together the more complex lifts .. and thus developing explosive power , and an awesome physique
