Athletic Adaptations is a sport science platform built specifically for martial artists. Whether you compete in judo, MMA, BJJ, wrestling or kickboxing — this app gives you the tools that elite athletes use, without needing a personal S&C coach. STRENGTH PROGRAMS Currently inlcuding ten evidence-based programs, each built around a specific goal or athlete profile. More to come! • GPP (General Physical Preparation) — build your foundation • Max Strength — peak force production • Speed & Power — explosive athleticism • S&P Retention — maintain strength during competition prep • Athletic Development — Olympic lifting and advanced compound work • Calisthenics Basics — bodyweight strength from the ground up • Low Impact — joint-friendly training without sacrificing results • Grappler Specific — built for wrestlers, judoka and BJJ athletes • Striker Specific — built for kickboxers, Muay Thai and boxing athletes • MMA Specific — full combat sport demands in one program Every session comes with progressive overload, auto-calculated load ranges and exercise substitutions. No guesswork — just follow the program. SPORT SCIENCE ANALYTICS Log your lifts and see your athletic profile come to life. Radar charts break down your strength across upper body, lower body, power, conditioning, grip and unilateral movement — mapped against elite-level benchmarks for your sport and gender. Know exactly where you're strong, where you're lagging, and what to prioritise next. WEIGHT CUT PROTOCOLS The most dangerous part of combat sports, done right. Enter your current weight, competition weight class and weigh-in date — and get a full personalised protocol covering: • Risk assessment (safe, moderate or high risk) • Caloric deficit guidelines • Fluid cut strategy • Sweat session protocols • Rehydration and refeed plan Built on sport science research. CONDITIONING Aerobic and anaerobic conditioning protocols tailored to your sport. Includes the 12-week MAS (Maximal Aerobic Speed) interval program with personalized wattage and intensity targets. PERIODIZATION PLANNING Set your competition date and get a phase-by-phase training plan — automatically structured around your fight calendar so you peak at the right moment. ELITE COACHING ACCESS Elite members get direct access to coach Joris Rookhuijzen (sport scientist, S&C coach, judo black belt, Olympic coach, PFL champion coach). Submit training videos for feedback, send messages, or book a personal call. Get a program built exactly for your situation. FREE TO START Download and start training for free. The basic programs, one weight cut protocol and core features are available without a subscription. Upgrade to Pro or Elite when you're ready for the full platform. Built by a sport scientist and martial artist who understands combat sports from the inside. Every feature exists because it solves a real problem fighters face.
