Ken Eriksen, 2020 Olympic Coach, says less is more when it comes to the pregame warmup. Briefly perform drills that practice basic skills, but avoid heavy teaching and verbal over-stimulation during warmups. The warmup is a time for players to feel comfortable in their skills, get the nerves out and develop confidence for the game.
Sometimes the length of the warmup will depend on the player. One pitcher may need a short warmup, while another pitcher might require an hour to feel physically and emotionally prepared. A warmup is not always about perfection; It's about developing adrenaline, warming up the athlete's body and practicing basic skills.
