BackMaxx: Back Muscle Builder

Build the back you actually want, and climb to 50 pull-ups in a row. BackMaxx scans your back with AI, builds a plan around what's lagging, runs a day-by-day pull-up program, and counts every rep with your camera. TODAY: WHAT TO DO, IN ONE SCREEN Open the app and Today shows exactly what's next: your pull-up day, your back session, or what to do on a rest day, each with the button that starts it. Doing both? Back sessions leave pull-ups to the program, so the two never double up. 50 PULL-UPS PROGRAM From your max today to 50 strict pull-ups in a row. Your max picks one of 11 tiers; each tier is 6 or 9 training days of 5 sets with rest days built in, then a retest that picks your next tier. Type the max you already know and Day 1 starts today, or test it with the camera. Missed a target? Choose where to pick the tier back up: Day 1, three days back, or retry the day. A calendar shows every session and test ahead. A CAMERA THAT COUNTS EVERY REP Prop your phone up and pull. Every rep is counted out loud and judged: chin over the bar, arms straight at the bottom. Kipping, swinging and half reps are flagged, so your number is honest. Then see range of motion, pull speed and tempo for the set. It runs on your iPhone: no video is recorded, stored or uploaded. YOUR BACK SCORE One photo with the selfie camera and a 5-second self-timer. The AI scores six back zones and eight individual muscles 0-100, lights them up on a muscle map, and names your strongest zone and your priority. Climb nine ranks from Newbie to GOAT. A PLAN BUILT ON YOUR WEAK ZONES Your program comes from your scan, your goals, your gym or home kit and how many sessions a week you can train, with extra volume where you need it most, form cues on every movement and progressive overload targets. Dial any session to Easy, Standard or Hard, or build a 15-minute express session. GUIDED SESSIONS Warm-up, main work, cool-down. Animated exercise guides, one lift at a time, rest timers that count you back in, swaps for the kit you have, personal records celebrated. PROVE IT'S WORKING Re-scan weekly: watch your score and rank climb, compare before/after photos and see your plan re-balance as zones catch up. Streaks, XP and trophies track every set, program day and rest day. BUILT PRIVATE Scan photos are analyzed transiently and never stored on our servers. Progress photos stay on your device. No account required. No ads. Scores are visual estimates for training motivation, not medical measurements or advice. BackMaxx Pro is an auto-renewing subscription (weekly or yearly).
