Hydration Equivalent Calculator
Not all drinks hydrate equally. Compare the hydration effectiveness of different beverages and see their water equivalent.
The gold standard

Why Hydration Matters for Lifters
Even mild dehydration (as little as 2% body weight loss from fluid) reduces strength output by up to 10%, impairs cognitive function, and delays recovery between sessions. For strength athletes, water is not optional — it's a performance variable as important as sleep and nutrition.
Water supports joint lubrication (critical with 13 damaged discs and bilateral hip replacements), nutrient transport to recovering muscles, temperature regulation during heavy sets, and waste removal. If your urine is dark yellow, you're already behind on hydration. The goal is pale yellow to clear throughout the day, with increased intake on training days.
Not All Fluids Are Created Equal
While this calculator shows beverage equivalents, plain water remains the gold standard. Coffee and tea count toward hydration (the diuretic effect is mild and offset by the fluid volume), but sugary drinks add empty calories. Electrolyte drinks are useful during long training sessions (90+ minutes) or in extreme heat but unnecessary for a standard 60-minute gym session. Alcohol is a net dehydrator — for every alcoholic drink, plan to add at least an equivalent volume of water. The simplest hydration strategy: keep a water bottle visible at all times and drink before you feel thirsty.
