As CrossFit becomes more and more popular, a greater amount of people will be exposed to Olympic Weightlifting. The Snatch and the Clean & Jerk are lifts that people spend their lives trying to master and then compete at the highest level against the best in the world at the Olympic Games. They are not something you can just learn in a couple of weeks.
I have seen a few people that are new to CrossFit that want to learn the O-Lifts, but that have no background knowledge of strength training. They want to learn how to Snatch, but don’t want to spend time working on their Squat. They don’t even realise how backwards that sounds.
Other people have remarked how complex the lifts are… yes, they are! You may need to spend weeks just working on the basics, before you even add any weight to the bar, (and that’s just for people who already know how to squat, deadlift and press). Then there are the variations to practice such as Hang Snatch, Hang Clean, Power Snatch, Power Clean, Snatch Balance, Clean Pulls… etc.
If you wish to become proficient in the Olympic lifts, it make take years to get there, but don’t try and rush it, the benefits they will bring to your training are extremely impressive. So listen to the trainers, be prepared to work on your technique and speed at lighter weights before moving onto heavier ones and accept that you are in for the long haul.
