JimLog

JimLog is a clear workout log for strength training. Plan your sessions, record your sets, and follow your progress. Your data is stored on your device, and the app works offline. BUILT FOR YOUR TIME AT THE GYM Log reps, weights, and timed exercises. See your set targets and record results as you train. Use the rest timer between sets and keep the screen awake during workouts if you prefer. Add notes and revisit previous sessions. DOUBLE PROGRESSION, LESS ADMIN Build reps within your chosen rep range. When your sets reach the top of the range, increase the weight and return to the lower end. Automatic progression updates your next workout targets from the results you log. You can also share an exercise's progression across workout templates. YOUR WORKOUTS, YOUR ROTATION Create workout templates from your own exercises and arrange them into a training rotation. Keep your next session in view. Build multiple rotations and include lighter deload workouts. In the exercise library, choose equipment, muscle groups, and how each exercise is logged. SEE YOUR PROGRESS AND MUSCLE LOAD • Review your workout history and completed sets. • Follow exercise progress and strength estimates based on the Brzycki formula. • Explore seven-day muscle training load on an anatomical body map, from the front and back. • Compare muscle-group set totals with your own targets. • Preview the calculated training load of a planned rotation. • Review a finished workout's total weight lifted, duration, and muscles trained. BACK UP AND MOVE YOUR DATA Save a full JSON backup and restore it in JimLog. Export workout history as CSV or import compatible history. Export and import workout templates or an entire rotation. Available in English and Finnish, with kilograms or pounds. No account, ads, subscriptions, or in-app purchases. Strength and muscle-load figures are calculated estimates based on your logged workouts. Privacy policy: https://jimlog.krpi.fi/privacy

Workout and rotation imports now review every exercise before importing, just like workout history imports. Match an existing exercise or create a new one, with equipment shown clearly. Suggestions distinguish machines, barbells, dumbbells and other equipment, and support Finnish and English exercise names. Your choices apply throughout the imported rotation and its workouts.
