They are more complicated than other “traditional” lifts, but not as much as some people believe. Dan John has always done a good job of simplifying the lifts and his video here does just that:
Glenn Pendlay also does a very good job of simplifying the performance of the lifts. For example his take on the double knee bend:
The best way to teach the double knee bend is to never say “double knee bend” and never ever let the athlete know that anything like that is supposed to happen. As soon as they know they are supposed to do it, half the battle is lost.
You teach the position of the top pull or second pull first, get comfortable with that, then teach going from that position to below the knees via ONLY hip flexion, then teach lowering the bar from the patellar ligament region to the floor via ONLY knee flexion. You encourage the athlete to raise the bar in the same manner as he is lowering it, and it is almost impossible to NOT do right. The only people who have trouble with it are those with an extensive history of doing things WRONG, or, maybe ex powerlifters who have been pulling off the floor differently for years and have trouble not relapsing into old habits.
It is really impossible to push the legs off the floor, go from the knee to a proper second pull position, then jump, without executing a double knee bend. So you emphasize the positions and let the knee bend happen all by itself.
Now if you want to become a high level competitive lifter, then you will need coaching for all the little nuances, but just to use them in a strength program, it probably isn’t necessary.
