Gymdex - Gym Exercise Tracker

Gymdex is a gym exercise catalog and a set-by-set workout log in one app. Pick what to train, check the form, tick off your sets, and watch your lifts move over time.

89 exercises across 10 muscle groups - chest, back, shoulders, arms, forearms, legs, glutes, core, cardio and full body - each with its own illustration.

WHO IT IS FOR
- New lifters staring at an unfamiliar machine with no idea where to start
- Anyone putting together a push/pull/legs or upper/lower split
- People still writing sets and reps in a notes app
- Lifters who want their volume on a chart rather than in their head

1. A CATALOG YOU BROWSE BY BODY PART
Tap a body part on the map and you are straight into its exercises: bench press and chest dips for chest, deadlifts and lat pulldowns for back, barbell squats and leg presses for legs, and so on. Filter by equipment - barbell, dumbbell, machine, cable, Smith machine, bodyweight, kettlebell, band, cardio - so you can train with whatever is open right now. Search finds a movement by its name, its body part or its equipment, and whatever you looked at last is still waiting on the home screen.

2. FORM, MISTAKES AND TIPS ON EVERY EXERCISE
Each exercise page walks through the movement step by step, then lists the mistakes beginners make most, practical tips, a five-star difficulty rating and the muscles it works. Prefer to watch it? One button opens a video search tuned to that exact movement.

3. YOUR OWN SPLIT
Name a plan - Chest day, Back and biceps - and drop exercises into it. Tag it with weekdays and the home screen suggests the right plan when that day comes round. Bookmark the movements you keep coming back to and pull them into any plan.

4. CHECK-OFF LOGGING
Start a session and every row arrives pre-filled with what you actually did last time. Reps are stored per set, so 12 / 10 / 8 is no problem, and weight is optional. Tick the box and the log is written. Finish a session you built on the fly and Gymdex offers to save it as a plan.

5. CALENDAR AND CHARTS
The log calendar shows what you trained on any given day. Per-exercise stats chart total volume over four weeks, twelve weeks or all time, plus reps per set, your personal record and how many sessions you have put in.

6. ADD YOUR OWN EXERCISES
Something missing from the catalog? Add it with a photo, set its body part, equipment, difficulty, target muscles and steps, then use it in plans and logs exactly like the built-in ones.
