Tell us what equipment you have. We build the exact workout to match it. StayActive is an AI fitness app made for beginners: the people who walk into a gym, or look at their home setup, with no idea where to start. Check off the equipment you own (dumbbells, a barbell, a bench, a pull-up bar, resistance bands, machines, or nothing at all), tell us your goal and how much time you have, and StayActive builds a real workout around exactly what you've got. Need one session for today? Train now has it ready in seconds. Want a full program? The AI builds a structured, multi-week plan in about a minute. Not a generic template recycled from a library.
