Physique competitors utilize carbohydrate back-loading and water manipulation (loading/restriction) as primary nutritional peaking strategies to enhance muscle fullness and definition immediately prior to competition.

If you are competing in a physique sport, expect to use carbohydrate back-loading and water/sodium manipulation in the week before your show. Most competitors start this 7 days prior. Be aware that your strategy may need to differ based on your sex and drug status (if applicable), as enhanced athletes often restrict water more aggressively and males/professionals tend to load sodium more frequently than females/amateurs.
