In all seriousness I can say that hands and snatch is a very philosophical question. Years of my coaching practice show: strong arms may not only not help, but also might prevent progress.
Of course, the work of your arms in snatch is a complex coordination between bones and muscles under a high load, including compression. There are different schools, methods and sequences to initially learn the snatch technique: some coaches learn to jump first and pay attention to the correct extension algorithm, others thoroughly master the progression of muscle snatch, and only then add jump elements and power position. Each of these progressions has their own merit.
Coming into the gym for a training session, I very often meet physically strong weightlifters who try to perform a power muscle snatch standing almost 85%. They believe and hope that a big power "reserve" will help them in snatch performance. Yes, muscle snatch is a good and necessary exercise for athletes of all levels, but have you ever wondered what the whole purpose of this exercise is?
In my opinion, the main goal of performing muscle snatch is to work out an arms movement pattern, and the right tempo for your muscles. I often hear from athletes that this exercise allows them to make their arm muscles stronger, strengthen ligaments and joints, and increases their confidence when catching. Yes, this exercise can make arms very strong, but in turn this can make them slow and bulky, and we all know how important arm speed is in snatch.
The thing is that in snatch, an athlete does not perform muscle snatch as an element of the movement at all. In fact, the mechanics of the arm work is similar, but the athlete does not lift the barbell up, but instead tries to get under it as quickly as possible. In this phase of the movement, the athlete provides a flight path at the expense of their arms which is as close to the body as possible.
Young and inexperienced athletes often do not catch the huge difference between the technique of a movement, and the power of a movement. As an example, beginning athletes, even at a warm-up with a 40-60% weight, going at the barbell as if they were going for a world record. Logically they should know the difference, but they get caught up in the moment.
Everyone knows that the coordination of snatch and catching position in the OH position represents a big problem for so many athletes. Therefor, my opinion is that a lot of attention needs to be given to both arms and shoulders with the help of various special exercises. Not in order to develop "goofy power," but to make the upper body flexible and mobile, and joints and ligaments reliable and elastic. This is because these qualities will not only improve your technique, but also protect you from injury if something goes wrong.
So, the main task of arms and the entire upper limbs is control, and to ensure the optimal trajectory of the barbell. Of course, the power of the arms makes a contribution to the snatch, but only by 20-30%, not by 85%.
My coach always told me that snatch is a jump, and as we know the jump is not carried out by arms, but by LEGS.
