Master Trainer replaces rigid workout templates with a context-aware AI routing engine. Instead of a chatbot, it is a system that understands your biomechanics and instantly adapts your daily session based on equipment, sleep, or sudden aches. Standout features include External Load Auditing to credit real-world labor, a gimmick-free tracking UI, and built-in EMOM and AMRAP timers. It is not just a workout logger; it is a chief of staff for your physical capacity.
