Being a good baseball player can be accomplished with some practice. Being a great player comes with practice, heart, and dedication. Here you will find some drills to help.
Fundamentals of bat swing
This is not a hard drill but done properly will strength your forearms, wrists, and biceps. You will need your game bat and room to swing. Set up in your normal stance legs slightly more then shoulder width apart with a slight bend at the knees. Front knee should be behind the the ankle. This starts the weight on the back leg. Take a small step back with your front leg toward your back leg, this should transfer most of your weight on the back leg. Hands should start at shoulder height with knob of bat pointing in opposite batters box. Head should be pointed toward the pitcher. They should not move while front leg is moving back. When the front leg reaches shoulder width you should touch the ball of the foot to the ground with a toe tap and begin bringing it forward. As the foot comes forward the hip should start to open toward the pitcher, front elbow should start to pull bat through, the back elbow should be bent and close to side, and back foot should be starting to rotate to where the heel is coming off the ground. The bat should continue through the hitting zone arms still bent till contact point creating a power V, head down on ball. After contact head comes up arm push through to finish above the shoulder. That is the proper swing technique taught to me. Many others have their own approach but this is a popular version. Do 10 sets of 10 everyday and you will See a difference in bat speed, swing technique and performance at the plate.
