The following videos are of Sam Mikulak's podium training from the 2013 World Championships in Belgium. Sam was a member of the 2012 US Olympic Team and is the current 2013 US All Around Champion. Unfortunately they missed filming his ring routine.
Podium training is where the athletes have the opportunity to go out into the arena and actually work on the competitive apparatus rather than being back in a training gym. Getting in several workouts in the arena prior to the start of the competition is very helpful is calming the nerves. At least a little!
