Goal workspace
Use bounded health and fitness arithmetic, then move into a source-owned activity or marathon workflow when symptoms, routines, nutrition decisions, or several owners must stay coordinated.
Explore Health, Body & FitnessDecision brief
A consent-based, dated health-and-activity record that separates calculator arithmetic from clinical, nutrition, and training decisions and keeps escalation visible.
You already know the question and need one bounded adult screening, energy-equation scenario, macro conversion, clock-time, pace, heart-rate-reserve, or body-composition calculation.
Health screening, an activity routine, an event, source-owned nutrition instructions, equipment/environment controls, several owners, and repeated reviews must stay coordinated.
Choose your path
Route a person to one bounded calculation or the smallest evidence-led activity/event workflow while keeping calculator limits, professional ownership, stop rules, and escalation visible.
Check pace, HRR, BMI, energy, macro, sleep, or body-composition arithmetic.
Choose One bounded calculation and review the selected tool’s formula, inputs, scope, and sources.
Gets a transparent result without diagnosis, clearance, prediction, or prescription.
Coordinate several decisions without assembling unsafe generic advice.
Choose Start or restart activity and enter the Fitness Project.
Consent, screening, access, nutrition boundaries, controls, and response review stay together.
Coordinate a high-consequence event plan.
Choose Prepare for an event and enter the Marathon Project.
Official event evidence, authored training, tested operations, stop rules, and handoff remain traceable.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
