About this beta, scope & limitations

Early beta · Notice reviewed October 14, 2026

This is a public demo of Michael Martiradonna's project. The reviewed library is complete; AI explanations are disabled and nothing you enter leaves this browser.

Gym Swap is an early beta for educational exercise exploration. It helps users browse documented movements, explore alternatives, and work through an existing workout. This release is intended for invited testers, exercise professionals, and individuals using it with appropriate professional guidance.

Professional guidance

Before performing exercises or activities explored through Gym Swap, obtain approval from an appropriately qualified medical professional and follow any restrictions or supervision they recommend. Exercise selection and execution should be reviewed with a qualified exercise professional.

Gym Swap does not provide medical clearance, diagnosis, treatment, rehabilitation prescriptions, or an assessment of your individual readiness. It cannot observe your technique or verify that equipment and surroundings are suitable.

Limits and responsible use

The exercise library and supported comparisons are incomplete. Written information and AI-generated explanations may contain errors or omissions. A suggested alternative or match label does not guarantee safety, suitability, equivalent training effects, or results.

Exercise involves risk. Do not use this tool to override professional advice, train through pain, improvise unsuitable equipment setups, or determine treatment for an injury. Users and supervising professionals remain responsible for evaluating the information and its application.

The app does not generate training programs or automatically convert weights, repetitions, or progression. In this release, a saved workout stays in the current browser and may be lost if browser storage is cleared.

About the creator

Gym Swap is developed by Michael Martiradonna, a NASM-certified fitness professional and personal trainer with nearly 20 years of exercise instruction and coaching experience. His work includes athletic performance, functional training, and practical movement for activities of daily living.

Michael is not a physician. This application supplements professional knowledge and judgment; it does not replace them.
