Plan
A routine that fits your training, with the freedom to make it your own.
A rotation, not a timetable
Your program repeats independently of weekdays, and Next up picks up where you left off.
Four ways to start
Choose Push/Pull/Legs, Upper/Lower, Full Body or Bro split, then make the plan yours.
Programs that fit
Save multiple programs, keep one active and build rotations of 1–14 days with workouts repeated wherever you need them.
Make a variant
Duplicate a workout or create a day-specific variant such as Push Day B, and rename workouts without losing their history.
Build your own workouts
Create unlimited workouts with your exercises, target sets, rest times and supersets.
Your music stays on
Exercise videos loop silently without interrupting your music and stay cached on your phone after the first download.
Your own exercises
Create up to 200 private exercises with equipment and muscle groups, then edit them or follow their history.
Find it offline
Search your on-device exercise library, filter by muscle and select several exercises at once, even offline.
Playback on your terms
Tap to pause or resume, with a still poster and Play video when Reduce Motion or Low Data Mode is enabled.
Keep your work
Deleting a program keeps its workouts and history, and removing a custom exercise from the library keeps it in your existing workouts and history.
Train
Know the target, log the set and stay with your workout.
Your set, ready to log.
Weight and reps are prefilled, with large weight and rep controls that use your preferred weight increment.
Your target is ready. Adjust it if you need to, then log the set.
Last time, right there
Each set shows what you lifted on that exercise and set number the last time you finished the same workout.
Log. Rest. Repeat.
Completing a set starts your rest timer automatically, with rest after the group when you train in supersets.
Your rest, in sight
Follow the current set and rest countdown on your Lock Screen and Dynamic Island.
Keep the session running
Leave the player to use the rest of the app while your workout continues in the bottom mini-player, or return with Resume on Home.
Machine busy? Do it later.
Move an exercise and the rest of its superset after the other exercises when equipment is busy.
Adapt as you go
Add, skip or reorder sets and exercises during your session.
Start with a blank slate
Begin an empty session and save it as a reusable workout when you finish.
Know the estimated workout time.
See an estimated duration before you start, based on the planned sets and rests.
Pause and pick up again
Pause or resume your workout and move through the exercise list as you train.
Progression
Your targets follow your training, with changes you can review before applying.
Targets that adapt to you
You approve every suggested change, so your targets follow what you actually lift.
Your first session sets the target.
Sets without targets take the values you actually lifted, included in Free.
60 kg × 8 becomes your target
Beat it. Approve what comes next.
Lift more than your target and SmartGains suggests what you actually lifted. Accept it, adjust it or dismiss it.
Previous target60 kg × 8You lifted62.5 kg × 8Suggested target62.5 kg × 8Miss it? Your target adapts with you.
Once: “Off days happen” and the target stays. Twice in a row on the same set at the same target: review a lower target.
Example with a 2.5 kg weight step: 77.5 × 7, then 80 × 6.
80 × 8 → 77.5 × 7 kg × reps · suggested after two misses
Initial targets are always Free. Target suggestions are included in your first three workouts that have suggestions, then continue with Pro Pro. Apply selected suggestions or all, edit or dismiss them, including offline.
Rough days and short sessions
A rough day gets “You showed up.” and keeps your targets unless you choose to review adjustments, while fewer than half your planned sets completed gets “Short session”.
Beyond weighted targetsPro
Bodyweight suggestions can add reps or weight you actually lifted; assisted exercises adjust reps while keeping the assistance weight unchanged.
Included in the first three workouts with suggestions, then Pro.
Keep your additions
Choose which exercises and sets added during a session become part of your saved workout, included in Free.
Finish on your terms
Resolve unchecked sets with “Mark done (target values)” where a target exists, “Leave skipped” or “Back to workout”.
Workout version historyPro
See what changed and which session produced each version, then restore an earlier version online, removing the newer versions.
