MassAffect is an AI-powered workout planner that builds personalized training programs around your body, your equipment, and your goals.

PERSONALIZED WORKOUT GENERATION Tell the AI your goals, equipment, and how you're feeling today. Get a fully structured workout in seconds - not a generic template, but a program built specifically for you.

INTELLIGENT PROGRESSIVE OVERLOAD The AI analyzes your recent performance and suggests precise load, rep, or volume adjustments session over session. No guesswork - just measurable progress.

FORM COACHING Get detailed form guidance for every exercise, including cues, common mistakes, and modifications for injuries or mobility limitations.

EXERCISE SWAPS Don't have the right equipment or not feeling an exercise? Swap it for an AI-selected alternative that targets the same muscles with what you have available.

CUSTOM INSTRUCTIONS Add your own training preferences, notes, or constraints in your own words. The AI incorporates your custom instructions into every workout it builds.

WORKOUT MEMORY MassAffect remembers how your recent sessions went - energy levels, difficulty ratings, and your own notes - and uses that context to make smarter programming decisions going forward.

GOAL-DRIVEN TRAINING Whether you're building lean muscle, losing weight, improving strength, or training for general fitness, your goal shapes exercise selection, volume, and intensity.
