Cutting water in peak week is one of the fastest ways to flatten your physique and compromise your stage look. Yet, it remains one of the most common last-minute “hacks” competitors fall for.
Why Water Matters
Muscle tissue is roughly 75% water. When you restrict hydration, you don’t tighten up, you remove fullness, vascularity, and the ability to achieve a proper pump on show day. Instead of looking crisp, you’re more likely to look flat.
Carbs and Glycogen Storage
Carbohydrates are stored in the muscle as glycogen, but glycogen binds to water. Consuming more carbs without sufficient hydration means they won’t be stored effectively, leaving muscles depleted instead of full and round. Hydration is non-negotiable for glycogen storage.
Intracellular vs Extracellular Fluid
The goal in peak week is to keep water inside the muscle (intracellular) where it drives fullness, not outside the muscle (extracellular) where it creates “spillover.” Dehydration flips this balance, worsening the very look athletes are trying to improve.
The Risks of Cutting Water
Beyond the visual drawbacks, water restriction also raises the risk of cramps, poor digestion, dizziness, headaches, and the inability to get a pump. These side effects drain stage presence and performance, all for the false promise of a “dry” look.
The Real Solution
Peak week is not about hacks or tricks, it’s about refinement. Conditioning is built through months of strategic fat loss, not a last-minute manipulation of hydration. The smarter approach is to keep water and sodium intake predictable, while using carbohydrate loading to achieve fullness. Don’t gamble months of preparation on a strategy that physiology doesn’t support. Keep hydration consistent, and trust the process that got you to peak week in the first place.
