Training · Fueling · Recovery
Understand the evidence. Know the limits.
Read educational guides about food, fluids, supplements, sleep and race fueling. Published research does not validate JMM as a complete intervention.
Supplements: a decision, not a default.
A supplement is optional. The evidence for one ingredient does not establish that a product, combination or dose is suitable for you—or that JMM has been clinically validated.
Performance aids need a specific question.
An aid may be studied for a particular sport, effort and population. That does not make it a useful daily habit for every athlete.
Sleep and recovery need context.
Notice your own pattern, current symptoms and life demands. A single wearable score cannot establish that you are recovered or cleared to train.
Food around the work you actually do.
Session duration, intensity, meals, tolerance and turnaround time matter. There is no single food-and-fluid template for every session or athlete.
Practice race fueling before race day.
Build logistics around the event, expected feeding opportunities and a dated intake you have practiced. A scenario total is not proof that an athlete can tolerate it.
Training needs an individual context
Review the goal, recent work, available time and source dates. A published study informs a discussion; it does not establish your ideal training mix. For HYROX, review running and stations separately.
