When you play on a sports team, you need to make sure that you are in good shape. If not, you could end up letting your teammates down. If you want to have a chance to play on a regular basis, you need to take steps to maintain a high level of physical fitness.
Just going to practice on a regular basis is usually not enough to stay in shape. You also need to make sure that you spend time exercising on your own. At practice, the goal is usually to improve your skills and work on plays, not to maintain your endurance or strength.
Focus on both strength and stamina during your workouts. If you neglect one area at the expense of the other, you will end up unbalanced. This means doing both strength training and cardio work so that you can be in great shape.
However, it is also important not to push yourself too hard too fast. Doing so will increase the risk of injury, which means that you will not be able to play at all. Pay attention to what your body tells you, and lower the intensity of your workouts if you need to.
Do not do too much in the days leading up to a game, either. You do not want to wear yourself out by working too hard so that you do not have anything left for the game. You need to make sure that you are ready to play at a high level throughout the contest.
Give your body time to rest and recover after a game. Do not just jump right back into intense workouts. Take a day or two to recover before you start working out again. This way, you can make sure that you are always ready to give it your all during a game.
