Common questions
Before you apply
Fight signed: Fight Camp, fight week included. Between fights: Fight Ready. Fighting all year and want it all: ACA 365. Not sure, apply and I'll tell you.
- Fight camps that drop fat while you stay fast and strong, with calories, macros and carbs matched to training.
- Fight week and rehydration plans, remote or in person, built to your promotion's rules and travel.
- Water cuts kept to the minimum, weigh-in strategy and the post weigh-in refuel.
- ONE Championship hydration test plans and USG checks. 35+ passes so far.
- Weight class and body composition checks that set a real walk-around weight and a safe cut limit.
- Gym and team workshops on safe weight cutting, hydration and refuelling.
8 to 12 weeks out is ideal. You make weight without crash dieting and turn up fuelled. Closer than that, message me. Fight week only support is there too, two week minimum.
Both. First amateur fight or world title defence, the principles don't change. Only the execution does.
Most camps run remotely with check-ins, plans and live support on WhatsApp. For title fights and high-risk cuts I fly out and run fight week in person: meal prep, weigh-in strategy, water cut, refuel.
Hydration testing is one of my specialisms. 35+ successful ONE Championship hydration passes, including fighters who had failed before. We build a plan for your scenario. No two are the same.
Combat sports is its own discipline. Weight classes, weigh-in formats, water cuts, fight week protocols and hydration tests are not covered well by general sports nutrition. I only work with fighters: MMA, Muay Thai, boxing and kickboxing.
It is when the cut is sized to you. Every fighter is screened first: weight history, weigh-in format and the time there is. Water cuts are kept to the minimum and the refuel is planned before the cut starts. Nothing on this page is medical advice. Everyone's different, so get tested.
It depends on the program and the length of camp. Apply, then we talk on WhatsApp to see which one fits before any numbers.
