World of Lifting (formerly PR.O) is the workout tracker built for lifters who care about progress, not guesswork. Log fast, beat your numbers and level up, whether you're chasing a bench PR, running a strength program or tracking progressive overload on every exercise. Every feature is free, for everyone. No ads, no paywall, no subscription. WHAT MAKES IT DIFFERENT • Classes and XP: every workout earns XP. Level up your Atlas and Spartan classes and unlock trophies for milestones and streaks. • Progress that compounds: build any progression scheme, with your own loads, reps and volume, so every session moves you forward. • Clear PR tracking: one-rep maxes, most reps and total volume on every exercise, with all-time and program PRs at a glance. • Fast mid-workout: fewer taps, clearer sets, no clutter. PROGRESSIVE OVERLOAD TRACKING Go beyond sets and reps. Track progression through weight, reps, time under tension, RIR, RPE and technique. Set exactly how each exercise progresses with flexible progression schemes that fit how you train. PROGRAMS AND PERIODIZATION Build multi-phase programs with progression built in. Start from templates for bodybuilding, strength, powerlifting, fat loss and conditioning, or design your own from scratch. EXERCISE LIBRARY A big exercise library with muscle targeting, video demos and equipment tags. Create custom exercises for your own setup, and sort them into collections by goal, equipment or muscle group. HABITS AND APPLE HEALTH Log bodyweight, sleep, food, water, caffeine, body measurements and more in one Habits screen. Set daily or weekly targets and watch the rings on Home turn green when you hit them. Import sleep, calories and macros, water, resting heart rate, HRV, active energy and cardio workouts from Apple Health, and save your weight, food, water, caffeine and waist entries back to it.
