How It Works
The best app for auto-regulated strength training: adaptive workout plans that change based on your sleep, recovery, and performance—no spreadsheets, no guesswork.
Set your goals & equipment
Choose strength, hypertrophy, or powerbuilding. Add your gym (home, commercial, or limited kit). Custom gym equipment filter so every session fits what you have.
Train & track
Complete workouts; the app tracks progressive overload and fatigue. Optional HealthKit sync uses sleep and HRV to tune volume—workout app that changes based on recovery.
Get your next session
Automatic periodization and plateau-breaker logic build the next workout. No deload guesswork: fatigue-based training that evolves with you.
Flux Workouts Features
Beyond tracking: Flux Workouts creates your next session from your current capacity. Every workout is built on your goals, equipment, and recovery—strength, hypertrophy, or powerbuilding.
Adaptive Pathing
Learns which movements drive your progress and balances your favourites with the variety you need to keep evolving—no more plateaus or boredom.
Recovery-Aware Training
Tracks how you're recovering so each session is tuned to how you actually feel. Train hard when you're ready and back off when you need to.
Smart Periodization
Guides when to push and when to ease off over weeks and months, so you stop guessing about deloads and peaks.
Workouts That Fit
Every session is built around your goals, equipment, and time. Tell the app what you have and how long you've got; it does the rest.
Progression That Sticks
Automatically advances your weights and reps using evidence-based methods so you're always training at the right level.
Learns Your Preferences
Picks up on the exercises you love and the ones you skip, so recommendations get more personal the more you use it.
