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.
