If it takes thousands of repetitions to be good at something and 10,000hrs to be an expert at something, then you better start now! But there have been plenty of people who have put in thousands of hours and they aren't elite...why not? Maybe they simply lack the talent but they should STILL be good...but some aren't.
That is because I believe that you need to practice perfect repetitions if you want to get better.
If you consistently practice your cleans or snatch, practice the same routine you would use as if you were going for the Olympic Gold Medal. Anything less would be not as efficient 🙂
Practice with deliberation...and enjoy the results 🙂
