AI Workout Planner

Read full description

Trackist is an AI coach that builds your workout plan, reads every set you log and adds load when you are ready. Same sessions, same numbers? Pick your goal, your days, your minutes and the gear you have. Trackist writes a plan for the week you really have, then writes a new one after every block from what you lifted. A PLAN BUILT AROUND YOU - Answer a few questions: goal, experience, training days, 30 to 90 minutes a session, equipment - Get a full block of 4 to 12 weeks: training days, sets, reps and rest - Start your first session today, or on the plan's first training day - Sore knee or shoulder? Flag the joint and the plan works around it - Change any day in the plan editor EVERY SET HAS A NUMBER TO BEAT - Log weight, reps and RPE in a few taps - Last time's numbers sit under every set, with a suggested load above them - A PR is marked the moment you hit it - Rest timer on the Lock Screen and in the Dynamic Island - Rack taken? Swap the exercise mid-workout - Every workout ends with your total volume against last time MORE THAN THE BARBELL - HYROX stations, sleds, carries and wall balls, in meters where HYROX counts meters - Olympic lifts, kettlebell swings, muscle-ups, rope climbs and other CrossFit moves - Cardio anywhere in the day: runs, rowing, bike erg, intervals - Bodyweight moves count your body weight in volume and records A COACH WHO REMEMBERS YOU - Slept badly or sore? Take today's session lighter: same weight, one set fewer, longer rest - Too hard, too easy, or something hurts? The coach changes the day or rebuilds the week - A new plan after every block: what moved stays, what stalled changes - A weekly recap in your coach's words, with your sleep and activity for the week - What you skip and where you stalled carries into the next plan PROGRESS YOU CAN SEE - Strength Score from 0 to 100, from your squat, hinge, push and pull - Strength Age: the age at which a typical lifter of your sex and weight is as strong as you - Momentum: weeks in a row you trained or moved for 20 minutes - Weight, a goal weight and measurements of chest, waist, hips, arms, thighs and calves, each compared with your first entry WORKS WITH APPLE HEALTH - Last night's sleep fills in before you train - Workouts from your Apple Watch appear on their day and count towards Momentum - Weight syncs both ways, and your average daily steps show on the dashboard TRACKIST PRO Training with Trackist needs Trackist Pro.
