Glycogen Depletion vs Water Loss: Two Different Cutting Tools
Serious competitors explain the science behind glycogen depletion and water loss as distinct weight-cutting strategies, and how to use each tool safely and effectively.
What Happens to Plasma Volume During a Water Cut
Plasma volume drops fast during a water cut, raising heart rate and impairing performance. Learn the physiology and how to manage it before competition.
Cutting Weight for Powerlifting: Different from Combat Sports
Powerlifting weight cuts differ sharply from combat sport cuts in timing, recovery demands, and risk tolerance. Here is what the science says.
The Cold Plunge Question: Does It Help After Heat Training?
Cold plunge after sauna suit training is trending, but the science on recovery versus heat adaptation is more complicated than social media suggests.
Hot Yoga vs Sauna Suit Training: Different Stresses, Different Risks
Hot yoga and sauna suit training both raise core temperature, but they impose distinct physiological stresses and carry different risks for competitive athletes.
Why Body Weight Returns Within Hours After a Sauna Suit Session
Science explains why the weight lost during a sauna suit session reappears within hours — and why that is exactly what competitive athletes need to understand.
Sweat Sodium Concentration: Why You Lose More Salt Than You Think
Sweat sodium loss is higher than most athletes expect. Science-backed breakdown of why sodium depletion matters for water cuts and performance.

A science-based breakdown of NCAA wrestling weight-cut regulations — what the evidence supports, where the rules fall short, and what athletes need to know.
Heat Acclimatization: Prep Your Body for Sauna Suit Training
Heat acclimatization reduces heat illness risk and improves performance in sauna suit training. Learn the science-backed protocol serious athletes use to adapt safely.
Pre-Weigh-In Hydration: The 36-Hour Protocol for Combat Athletes
A science-backed 36-hour rehydration protocol for combat athletes who cut water weight with sauna suits before competition weigh-ins.
Pre-Competition Sauna Suit Tapering: A 7-Day Wind-Down
A structured 7-day sauna suit taper helps combat sport athletes shed water weight safely while preserving strength and avoiding heat illness before weigh-in.
Sauna Suit Materials Compared: Neoprene vs Nylon vs PVC
A science-backed comparison of neoprene, nylon, and PVC sauna suit materials to help combat sport athletes choose the right option for safe weight cuts.
Sleep Loss and Dehydration: Why Cutting Before Bed Backfires
Wearing a sauna suit to bed seems efficient, but sleep disruption compounds dehydration risk and impairs the recovery athletes need most before competition.
Caffeine and Sauna Suit Training: The Diuretic Trap
Combining caffeine with sauna suit sessions amplifies dehydration risk in ways most athletes underestimate. Here is what the science actually says.
Cardio Intensity and Sweat Output: Why HIIT Cuts Burn You Out Faster
High-intensity intervals inside a sauna suit spike core temperature and sweat rate faster than steady-state cardio, raising heat illness risk during weight cuts.
Body Fat vs Lean Mass: How Your Composition Changes Your Cut
A fighter's body fat percentage directly affects how much water weight they can safely cut. Learn the physiology behind composition-based weight cutting.
