Pre-workout formulas vary, so begin with the directions on your pack. Many people prefer to take a serving before training with enough time to settle into their session.
Pay attention to caffeine
Check the caffeine per serving and account for coffee, tea and other sources throughout the day. Start with a smaller amount to assess your tolerance if the label allows it. Late sessions may call for a caffeine-free option, since caffeine can interfere with sleep.
Food and hydration matter
A familiar meal or snack and adequate fluids can help you feel ready to train. Avoid exceeding the labelled serving and consult a healthcare professional if you are sensitive to stimulants, have a medical condition or take medication.
