Liftosaur is the most customizable weightlifting app and strength training tracker and planner. # Automate Your Strength Training Build your own progressive overload programs or start with proven routines like GZCLP, 5/3/1, or Basic Beginner Routine. Track every workout, visualize your progress, and fully automate your training — all in one smart fitness app. Stop guessing your next weight. Liftosaur automatically increases or decreases your weights and reps based on the logic you define. It allows to implement any possible progressive overload logic, so you can focus on lifting while the app handles the math. Liftosaur introduces Liftoscript — a simple text language for building workouts like code. Define exercises, sets, and logic once right in text, and the app updates it automatically after each session. Example: ``` # Week 1 ## Day 1 Bent Over Row / 2x5, 1x5+ / 95lb / progress: lp(2.5lb) Bench Press / 2x5, 1x5+ / 45lb / progress: lp(2.5lb) Squat / 2x5, 1x5+ / 45lb / progress: lp(5lb) ## Day 2 Chin Up / 2x5, 1x5+ / 0lb / progress: lp(2.5lb) Overhead Press / 2x5, 1x5+ / 45lb / progress: lp(2.5lb) Deadlift / 2x5, 1x5+ / 95lb / progress: lp(5lb) ``` This makes Liftosaur the only scriptable workout app — perfect for lifters who love structure, logic, and data. # Popular Programs Included Liftosaur comes with pre-built lifting programs and templates from the strength community: • All GZCL programs: GZCLP, P-Zero, The Rippler, VHF, VDIP, General Gainz, etc • 5/3/1 and its variations • Basic Beginner Routine from r/Fitness • Strong Curves • And many more! Every program is written in Liftoscript, so you can customize every detail — sets, reps, progression rules, and deloads. # Track Everything Liftosaur isn’t just a gym tracker — it’s your complete workout planner and data companion. • Rest timers & plate calculator • Body weight and measurement tracking • Graphs for exercises and progress over time • Equipment rounding & exercise substitutions • Cloud backup and cross-device sync • Web Editor for faster program creation on desktop # Made for Powerlifters and Beginners Alike Whether you’re starting your first strength program or fine-tuning an advanced powerlifting routine, Liftosaur adapts to your style. It’s a lifting program builder, progress tracker, and gym log app — all working together to make you stronger. Weightlifting is a long game, and if you're serious about lifting, building strength and sculpting your body, Liftosaur would be a great partner in your journey.
