Avoid Caffeine
Caffeine may boost your level alertness, but it can increase your heartbeat and anxiety. While it is not a bad idea to take caffeinated drinks, gulping large portions of it can be counter-productive. Examples of caffeine are soft drinks, coffee, chocolate and ice cream.
Do not eat too much food
Food is essential for the body. It is the fuel that lubricates it. However, when it comes to working out, there are foods you should avoid. Before you workout, you can take foods like cereal, banana, yogurt and oats while avoiding fatty meals. As long as you do not overfeed, you should be fine.
