GymForge: Serious Lifting - Zero Distractions - Proper Form Mastery Stop wrestling with complicated workout apps. GymForge gives dedicated lifters a simple yet powerful way to build, track, and master workouts. Its clean, native interface keeps your focus on training โ not on figuring out the app. Key Features: - TRACK PROGRESS WITH PERSONALIZED INSIGHTS: Your Dashboard provides Quick Start access to recent workouts and insights. View training consistency on a calendar heatmap, track volume moved, monitor training time, and visualize personal records over time โ all with customizable time periods from weekly to yearly views. - CREATE YOUR PERFECT PLAN: Intuitively build truly custom routines. Add, remove, and sort exercises; set target sets with flexible rep modes (fixed reps, rep ranges, or AMRAP); and configure optional RPE targets as a single value, a range, or per set โ your way, with fewer taps. - SMART PROGRESSION GUIDANCE: NextLoad indicators analyze your performance and suggest whether to increase, maintain, or decrease weight for your next session. Combined with automatic weight increments, progressive overload has never been easier. - PAUSE & RESUME ANYTIME: Life happens. Pause your workout mid-session and pick up exactly where you left off, right from your dashboard. - DEFINE EXERCISES YOUR WAY: Tailor exercise names, descriptions, and muscles, and link YouTube videos (with custom timestamps) for technique reference. Track history and personal records for every exercise. - MUSCLE MAP: See exactly what every exercise trains. Tag primary and secondary muscles โ or accept a smart suggestion โ and view them on a front and back body map, male or female. - EXERCISE VARIANTS: Add alternatives to any exercise, even mid-workout, and swap on the fly. The picker remembers your last pick. - REST TIMER BETWEEN SETS: Stay on pace with a floating rest timer that starts after each set. Use a fixed rest time or a range โ the color-coded bar shows when you're ready to lift and when you've rested too long. Set a global default or customize per exercise. - APPLE HEALTH INTEGRATION: Every workout automatically saves to Apple Health with duration and calories burned. Your training flows into your overall health picture. - CELEBRATE PERSONAL RECORDS: Automatically detects new personal bests for weight and volume. Finish your workout and instantly see which PRs you crushed, with previous bests for comparison. - TRACK WORKOUTS WITH ZERO FRICTION: Log weights, sets, reps, and RPE effortlessly with a built-in workout timer and rest timer. Access form videos mid-workout when you need them most. - FIND EXERCISES INSTANTLY: Smart search by name or body part gets you to the exercise you need, fast. - REVIEW & REFINE YOUR JOURNEY: Easily monitor progress by looking back at past workout sessions. Edit completed workouts to correct any mistakes with full data integrity. - EXPORT YOUR DATA: Export completed workouts to CSV for detailed analysis in any spreadsheet app. Choose a date range or export everything at once. Whether you train with progressive overload, RPE, AMRAP sets, or a focus on technique, GymForge adapts to your method. Free Features Include: Complete workout tracking, automatic personal record detection, Apple Health integration, exercise video integration with trim controls, muscle map, consistency heatmap, pause/resume workouts, up to 3 workout plans, iCloud sync, and more.
