BUILD BROADER SHOULDERS. TRAIN FOR YOUR FRAME.
ShoulderMaxx is built for one goal: helping you build broader, stronger-looking shoulders with training personalized to your physique.
HOW SHOULDERMAXX WORKS:
1. Take a photo and let AI analyze your shoulder structure and proportions.
2. Discover the areas holding back your broader-shoulder look.
3. Unlock your personalized shoulder routine built around your weak zones, experience, and equipment with ShoulderMaxx Pro.
4. Train, rescan, and watch your frame develop over time.
Most workout apps give everyone the same shoulder exercises.
ShoulderMaxx builds your training around YOU.
Your scan analyzes key characteristics of your frame, including shoulder width, shoulder-to-waist proportions, shoulder roundness, symmetry, and shoulder positioning.
Then ShoulderMaxx turns that analysis into a targeted training plan designed to prioritize the areas that need the most work.
If shoulder width is holding you back, your training can prioritize your lateral delts.
If your shoulders lack a rounded appearance, your routine can put more emphasis on complete delt development.
If your shoulder positioning needs work, supporting exercises can be incorporated into your plan.
NO MORE GUESSING WHAT TO TRAIN.
Your workouts adapt as you progress.
Track your exercises, reps, sets and performance. Complete your weekly scan to see how your physique changes and keep your training focused on what needs improvement.
