Your plan, your way. Import a workout from your notes, screenshot one from your feed, build your own, or pick from 20 ready-to-run templates. Then track every set, with next-session weights that adjust to what you actually lifted. No generic plan generator. No motivational filler. Just a tool for lifters who want progressive overload done properly. IMPORT FROM YOUR NOTES Got a workout plan stuck in your notes? Paste it into rep by rep and we match the exercises against our 1,500-exercise library. Each one comes with a form video so you can start tracking straight away. IMPORT FROM YOUR FEED Sick of scrolling and saving workouts you never get to use? Screenshot a workout from Instagram, Reddit, or anywhere else, drop it in the app, and we'll turn it into a trackable session with videos. 20 READY-TO-RUN TEMPLATES Linear 5×5. Push Pull Legs. Upper/Lower. Powerbuilding. Hypertrophy Mesocycle. Smolov Jr Bench. Wave Periodised. Twenty proven programs, ready to load in a tap. BUILD YOUR OWN Prefer to roll your own? Build a routine from scratch around the lifts you actually care about. Add, swap, and reorder exercises however you want. WEIGHT SUGGESTIONS THAT ADJUST After each session, rep by rep suggests your next session's weights based on how the last one went. Reps, effort, and load are all factored in. Hit your target reps and the next session bumps the weight. Didn't? It holds. Simple, honest progressive overload. 1,500+ EXERCISES WITH FORM VIDEOS Across dumbbell, barbell, machine, cable, calisthenics, and other equipment. Every exercise has a video demonstration, form cues, equipment requirements, and substitutions for when you don't have what you need. YOGA AND RECOVERY Rest days get the same treatment. Routines for mobility, recovery, and mornings: Unwind, Wake Up, Deep Recovery, Full Body Flow, Unlock Hips, and more. PROGRESS YOU CAN MEASURE PRs tracked automatically. Set a goal weight on any lift and watch your projected e1RM track toward it. A body heatmap shows the muscles you've actually trained, so you can see what's getting worked and what's being skipped. Volume and intensity trends over time. OFFLINE-FIRST Plans, exercises, logging, and weight suggestions all work without a connection. Train in basements, garages, dead-zone gyms, or on a plane. Videos stream when you're online. WHO IT'S FOR rep by rep is for people who already know they want to train and just need the structure. Beginners get a starting point and clear next steps. Intermediate and advanced lifters get a tool that matches how seriously they take it. PRIVACY Your training data stays on your device by default. No ads. No third-party trackers.
