The first video is a short documentary on the Russian Junior National Weightlifting Team. It's no wonder that Russian and other former Soviet bloc countries are so dominate in international competitions - they are well funded and take training and their sport VERY seriously.
The second video is of Ilya Ilin, a 94kg Olympic and World Champion weightlifter from Kazakstan, working up to a 240kg (528lbs) clean & jerk. The big thing to take away here is that the technique and tempo don't really change from "lighter" weight to max weight. Dialed in!
As an aside, I competed in the Copperhead this past weekend up in North Texas, and did very well. Stay tuned for some videos and breakdown of how it went.
