In this solo podcast episode, Kelsey Poulter of Next Level Athletes explains why proper hydration and electrolyte balance are critical for athletic performance and provides a step‑by‑step, individualized hydration plan. She opens with a vivid high‑school anecdote about a lineman who suffered cramps from severe dehydration, then details how losing just 1–2 % of body weight through sweat impairs heart rate, core temperature, glycogen use, power, reaction time, focus and accelerates fatigue. Poulter cites an International Society of Sports Nutrition study showing that athletes who followed a personalized hydration protocol outperformed a control group in power, reaction speed and heart‑rate recovery. She reviews the five key electrolytes—sodium, potassium, calcium, magnesium, chloride—their physiological roles, food sources, and the dangers of both deficiency (cramps, low blood pressure) and excess water intake (hyponatremia). The core of the episode is a practical calculation method: baseline daily fluid = body weight (lb) ÷ 2 oz; practice fluid = body weight ÷ 30 oz per 15–20 min (×4 for 15‑min intervals or ×3 for 20‑min); post‑workout fluid = 12–20 oz added to baseline. Sodium needs are set at 500–1,000 mg/hr for heavy sweaters or 200–300 mg/hr for light sweaters, with ~500 mg post‑workout. She recommends tools such as sweat patches and pre/post‑practice weigh‑ins to fine‑tune the plan, stresses whole‑food sources for electrolytes, and adds medical cautions for individuals with kidney issues. The episode concludes with actionable takeaways: drink consistently, use whole foods, monitor weight changes, trust your body, and seek professional or program support if needed.
