Hello,
Beyond the conditioning, I think that the technique is important too really reap the benefits of any exercise: jump rope, swings, snatches, etc...
As far as high rep drills are concerned, I enjoy polishing my technique with a light weight, after a session or in the evening. I do not do a lot, just a few reps to create the movement pattern.
The good thing about snatches is that they require a lot of volume, so you will progress super fast !
I think we never really suck, we just are in a not that good place of the learning curve, for a short while
As a French saying says : we have to learn how to walk before learning how to run.
Kind regards,
Pet'
