About Rhyse

Elite practice, without the guesswork

Rhyse is a registered Sport and Exercise Nutritionist (SENr) with a BSc and MSc across Sports Science and Nutrition. He has extensive experience working with a variety of athletes and teams across multiple sports, particularly within Premier League football, Premiership rugby and European competition, from first-team players to academy athletes. He is currently working with Crystal Palace and Charlton Athletic to lead their club nutrition provision, as well as being Head of Nutrition for PWR Performance working with a range of athletes, supporting league seasons, competition prep, fight camps and injury rehabilitation.

That’s how I support you: reading the demands of your week, working alongside your physio, strength coach, chef and anyone else in your corner, and making sure the plan holds up in training, on match or competition day, in rehab and on the road.

Areas of support

Every part of your performance

Performance fuelling

Nutrition for training, match and competition days, from league seasons and fight camps to races, tournaments and the gym floor, planned around each athlete’s week.

Injury rehabilitation

Phased nutrition for long-term rehab, working with the medical team from surgery through to return to play.

Immunity and illness

Fuelling that keeps athletes available through heavy training blocks, travel and winter, and supports a safe return after illness.

Body composition

DEXA and skinfold monitoring, interpreted against each athlete’s position, goals and meaningful change.

Sleep and energy

Nutrition for better sleep, steadier energy and less fatigue, built around training load, travel and a busy schedule.

Hydration and recovery

Individual fluid, electrolyte and recovery plans, built around how each athlete sweats, sleeps and trains.

Supplements and clean sport

Evidence-based, batch-tested supplement guidance that keeps athletes inside anti-doping rules.

Travel and competition prep

Plans for away days, tournaments and trips, so fuelling holds up wherever the competition is.

Education

Workshops and resources for athletes, parents, coaches and practitioners that turn the science into simple habits.

How it works

From first call to full plan

  1. Discovery call

    We talk through your goal and your schedule, and whether we’re a good fit.

  2. Questionnaire

    You complete your health, supplement and lifestyle details, so our time isn’t spent on paperwork.

  3. 60-minute consultation

    We map your goal, your routine and your training, then agree two or three priorities.

  4. Your individualised plan

    Within 3 to 5 working days, you get a plan built around your training, competitions and the food you enjoy, with daily and meal-by-meal targets that adjust in real time and nutrition tracking in your app.

  5. Review and adapt

    Check-ins, performance reports and plan updates, at the level your tier includes.
