Stop writing workouts from scratch. Personal trAIner PRO is an AI programming assistant and client management app built for professional personal trainers. It plans each client's training the way you coach, so your time goes into coaching instead of spreadsheets. PROGRAMS THE WAY YOU COACH Set up your Trainer Profile in four short screens: your training focus, programming tendencies, progression method, exercise rotation and effort scale (RPE, RIR or %1RM). Every plan and session follows your approach, not a generic template. It picks up on your habits too. Swap the same exercise out repeatedly and it's automatically de-prioritized. Your hard limits stay hard. Your effort cap, the movements you avoid, each client's equipment and their current pain are enforced on every session, not left to the AI. LONG-TERM PLANS AND SESSIONS Each client gets a long-term training plan built from their goals and your preferences, laid out block by block in the Roadmap. Generate today's session in a few taps: warm-up, main work, sets, reps, rest, effort targets, tempo and coaching cues. Loads come from each client's logged lifts. If a client is sore or needs a lighter day, tap the sore spot or add a quick note, and the session works around it. Every session is a draft. Edit, reorder or swap any exercise, or regenerate the whole session. CLIENT INTAKE AND WAIVERS Send new clients a link to an intake form they complete on their own phone: goals, training history, injuries, PAR-Q health screening, home equipment and contact details. Clients sign your waiver in the form. Use the built-in waiver or your own, and add your cancellation, lateness and payment policies. Answers are summarized into a draft client profile that you review before anything is saved. CLIENT PROFILES AND PROGRESS Goals, injuries, health screening, equipment for every training location and full session history, all in one place. Log each session with how it felt, pain flags and notes. Benchmark lifts are charted over time and used to set loads for the next session. BUILT FOR PROFESSIONALS Personal trAIner PRO is a tool for trainers, not a consumer workout app. Your clients never need to download anything. Whether you train 10 clients or 40, it handles the programming so you can focus on coaching. TRY IT FREE Generate your first 4 AI sessions free, with no subscription required.
