Scan your back, get your Back Score, and train the zones that are actually lagging. Weekly AI re-scans adapt your plan as you grow.
Train the back you can't see. BackMaxx photographs your back, scores six zones with AI, and builds a training plan around what's actually lagging.
YOUR BACK SCORE
One photo with the selfie camera and a 5-second self-timer. The AI maps lat width, upper back, traps, rear delts, lower back and symmetry, scores each zone 0-100, and names your strongest zone and your priority. Earn a rank - Rookie, Builder, Forged, Sculpted, Elite - and see where you stand among BackMaxx users.
A PLAN BUILT ON YOUR WEAK ZONES
No generic templates. Your program is generated from your scan, your goals, your gym-or-home setup and how many sessions a week you can honestly 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.
FOCUS PROGRAMS
Run a block that leads every session with one goal: V-Taper Sprint, Thickness Block, Traps & Rear Delts, Pull-Up Progression, Posture Reset. Your scan still fills the rest of the week.
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, scroll your photo timeline, and see the zone map fill out. Your plan re-balances automatically as zones catch up. Share your Back Score card when you're proud of it.
TRACK EVERY SESSION
Log sets with one tap, keep your weekly streak alive, and earn trophies for milestones - first scan, 10 sessions, +10 Back Score, weak zone fixed, and more.
BUILT PRIVATE
Photos are analyzed transiently and never stored on our servers. Progress photos stay on your device. No account, no email, no ads.
Scores are visual estimates for training motivation - not medical measurements or advice.
