Before training you can eat some type of amino acid such as the well-known BCCAs that give you additional energy to carry out your routines and that allow you to feel motivated during the training session.

You can also prefer solid foods such as eating a fruit or a snack that has carbohydrates, which will be absorbed by your muscles while you exercise.

Personally, I do not advise consuming protein before exercising, because it represents a heavier load for your digestion and you will be in constant movement so you can lose electrolytes, vomit and even faint. In my particular case, I recommend, if necessary, to consume light things such as fruits or snacks.

Remember if you eat food before training you should wait a reasonable time around 40 minutes before starting to perform and exercises and that they fulfill your objective of providing you with energy during the training session. Remember to bring a hydrating drink with which you can have drinks during the session in case you have a loss of electrolytes.
