## What is HyNext?

HyNext. Built for muscle growth.

No more working out how much to add next time. HyNext looks at how many reps you actually did in every set and plans your next weights and reps.

Every recommendation says where it comes from: research, common coaching practice, or HyNext's own method.

The engine plans it for you. If you disagree, you can change it any time.

Free
・Generates a program from your training experience, body type and the look you want, your goal, available equipment and training days per week
・Log every set, exercise library with how-to guides, history and personal bests
・Optional sign-in and cloud backup, so your training log comes with you to a new phone

Full version (all features free for the first 14 days, counted from the first time you open the app, no payment needed)
・Decides after every workout whether to add weight, hold or drop
・Gives you a little more rest when your reps drop too much between sets
・Explains why you are stuck and what to do next, not just "keep going"
・Adds sets in small steps during a muscle-gain phase, and watches for two weeks after each increase before asking again; suggests a deload when recovery can't keep up
・Make up or skip missed sessions
・Weekly reports, a yearly review, body weight and per-exercise trends
・The evidence and studies behind every recommendation

No ads.

## Version history (last 5 releases)

### 1.6 — 2026-10-27

・No more guessed weights for weighted exercises you are trying for the first time: use “Warm up to find your weight” at the start of your workout, starting with the lightest weight and working up set by set, or choose your own weight
・Quick workouts: set the number of sets for each exercise, with a simpler layout and an estimated workout duration
・Post-workout share cards: resistance-band-only and bodyweight workouts now show total reps and the level used in the session
・Feedback for timed exercises now uses seconds
・Fixed occasional screen flickering when switching exercises, plus text improvements and other small fixes

### 1.5 — 2026-10-22

・Program links from friends now open right in the app
・Home now lets you know when a new version is out
・Pick just the exercises you want when adding sets
・Set your dumbbell steps mid-workout
・A quick check when a logged weight looks like a typo
・Push-ups now level up at 25 reps per set
・Bug fixes

### 1.4 — 2026-10-18

・Smarter weight increases, based on your first set of the session
・Set your own dumbbell steps, even mid-workout
・Celebrations when you move up in weight, plus a pain check before adding load
・Shorter, clearer next steps when you're stuck

### 1.3 — 2026-10-12

New English version: choose Traditional Chinese or English on first launch or on the Account page.
A shorter, clearer beginner tour.
Effort check after each set is now "Too easy / Just right / Almost failed", compared with what the screen asked for, so there's nothing to calculate.
New: send your training results to HyNext anonymously (never public) to help tune its recommendations. Voluntary and off by default.
Simpler weight increases: hit the target this session and the weight goes up.
Plus many smaller fixes.

### 1.2 — 2026-10-09
