Gym Nerd

GymNerd is a complete training companion built for lifters who don't want to mess around. Generate a smart workout, follow it, log it, and watch yourself get stronger. No accounts. No paywalls. No internet required.

GENERATE A WORKOUT IN SECONDS
Pick the muscles you want to train, choose your week phase, set how long you have, and GymNerd builds you a fresh routine from a library of 400+ exercises. Compounds first, isolations second, intensity techniques in week three. Time-budgeted so you actually finish on time.

THE 3-WEEK CYCLE
Train heavy in Week 1 with 6–8 reps and slow tempo. Switch to moderate volume in Week 2 with 10–12 reps. Push to high-rep intensity in Week 3 with drop sets and rest-pause. Each week has its own color, its own pace, its own job. Cycle and repeat.

TAP YOUR MUSCLES
Choose body parts the way you think about them — tap directly on an anatomical body diagram, or use a fast pill grid. Both work. Selections stay synced.

CARDIO THAT KNOWS WHAT IT'S DOING
Six structured cardio protocols — HIIT, Long Intervals, LISS, Incline Burn, Pyramid, Tempo. Pick your modality (treadmill, bike, rower, stair, outdoor), choose intensity and duration, and the timer auto-advances through every work and rest interval with audio cues.

ABS BY FOCUS AREA
Generate ab routines targeted at the rectus, obliques, core stability, hip flexion, or mixed. Time-based holds for isometrics, rep-based prescriptions for dynamic moves. Same phase rules apply.

LOG EVERY SET
Tap into any generated workout to start logging. Weight × reps per set, checkbox per set, automatic rest timer between sets. A built-in plate calculator next to every weight input — no more mental math at 6 AM.

CELEBRATE THE WINS
GymNerd detects personal records automatically. Beat your previous best on any lift and the post-workout summary tells you so. Track total volume, time trained, and PRs hit per session.

WATCH YOURSELF IMPROVE
Tap any exercise in your history to see a clean progression chart of your best set per day. Log body weight in seconds and see the trend over time.

We don't want your email, your card, or your data. GymNerd runs entirely on your iPhone — every workout you generate, every set you log, every pound you track stays on your device. No servers. No accounts. No analytics. Open the app, train, close it.
