Read full descriptionHide full description
trainerX is an AI personal trainer for people getting back into the gym after a break. You used to train. Then work, kids, an injury, or just the slow drift got in the way. Now you're back, or trying to be โ and nothing quite fits. Generic apps hand you beginner templates you outgrew years ago. A real trainer runs $50โ$90 an hour and needs a standing appointment you can never keep. trainerX writes the session instead. Every time. WHAT IT ACTUALLY DOES โข Picks your weights for you Walk in knowing exactly what to do โ exercises, sets, reps and a suggested weight for every set, based on how long you've been out and what you lifted last time. No guessing. No starting too heavy and paying for it all week. โข Builds the session around your week, not an ideal one Tell it your goal, the days you can train, how long you've got and what equipment your gym has. Sessions pair a lower-body exercise with an upper-body one, so a real workout fits into 45 minutes instead of 90. โข Adjusts to what you actually did Every set gets logged. You say how the session felt. The next one moves up or backs off accordingly โ the judgment a good coach makes for you between sessions. โข Keeps going when life doesn't Miss a week? Tweak a knee? trainerX reworks the plan and picks up where you are, not where you meant to be. No streak to lose. No starting over. โข Answers questions mid-session Ask what a Romanian deadlift should feel like, why you're pairing these two exercises, or whether that ache is normal. Plain English, between sets, at 6am or 11pm. No booking. No $75 hourly rate. โข Shows you how Demonstrations and form cues on every exercise, so you're not copying the person who was on the machine before you. โข Swaps exercises when the gym is busy Squat rack taken? Ask for an alternative and get a real replacement that trains the same thing with whatever's free. โข Times your rest The timer starts the moment you log a set. Rest is the first thing that goes wrong on a phone, and it's what decides whether the next set is any good. โข Reminds you on the days you said you'd train A nudge, not a guilt trip. Showing up is the whole game. WHO IT'S FOR People in their 30s, 40s and 50s who trained before and want to again. Men and women. Time-poor, often with kids, usually with a joint that complains. If you can train three times a week for 45 minutes, that's enough โ and it's what trainerX is built around. Start your first session today.
