Stop Starting Over.
Start Getting Results.
See what you lifted last time. Beat it this time. That's progressive overload - and it's how real strength is built.
Sound Familiar?
The Forgetter
You walk up to the bench press and think... "What did I lift last week?" Then you guess. Then you plateau. Same weights, month after month.
The Notepad Warrior
You've tried spreadsheets. Notes apps. Paper notebooks. But nothing shows you what to lift today based on what you did before.
The Wanderer
You walk into the gym without a plan. Do some curls. Maybe chest? Whatever's free. An hour later you leave wondering if you actually accomplished anything.
The Restarter
New program every few weeks. "This time it'll be different." But you never stick with anything long enough to see results. The cycle continues.
We built Serkit because we were tired of the same problems.
Walk Into Every Session
Knowing What to Beat
No more guessing what you lifted last week. No more winging it. Just clear targets and visible progress.

Context-Aware Progress Tracking
Serkit doesn't just remember what you lifted. It remembers the exact context: which routine, which block, which round, which set. So your heavy squat day and light squat day maintain separate progress histories.
- See your history at a glance Your previous weight and reps appear right when you need them
- Multi-round awareness Circuit training? Each round tracks separately
- Safe routine changes Reorganize exercises without losing progress data
- Adapts to set changes Add or remove sets and the system adjusts intelligently
Build Any Workout You Can Imagine
From simple strength programs to complex periodization. Serkit adapts to your training style, not the other way around.
- Multi-variant routines Pro Heavy day and light day in one routine with automatic rotation.
- Session-only modifications Swap exercises today without changing your saved routine
- Freeform workout mode Start without a plan, add exercises as you go, save as routine later
- Blocks and circuits Organize exercises into blocks with their own rest periods and rounds
Training that keeps you accountable
Set clear expectations for your training, then track how well you follow through. The schedule flexes when life does, without losing momentum.
- Flexible scheduling rules Train on specific days, every N days, weekly or monthly targets, or flexible time windows
- Recurring schedules Pro Set up "Every Monday" or "Every 3 days" schedules. Free users can create one-off schedules.
- Completion tracking See what you completed, skipped, or moved, and stay honest with yourself
- Reminders on your terms Get nudges that support consistency, not guilt
Stay in the Zone, Start to Finish
Whether you're holding a stretch, resting between heavy sets, or flowing through a mobility routine - the timer keeps you present and moving without watching the clock.
- Perfect for timed holds Stretching, planks, mobility work - set your duration and focus on the movement
- Optional auto-progression through exercises Flow from one movement to the next automatically - ideal for yoga and flexibility routines
- Customizable rest periods Heavy lifting needs longer rest; supersets need quick transitions - set each rest differently
- Screen stays on Glance at your phone mid-stretch without fumbling to wake it up

Why Serkit Over
Everything Else?
Most apps track workouts. Serkit tracks progress. There's a difference.
| What Matters | Other Trackers | Spreadsheets | Serkit |
|---|---|---|---|
| Context-aware history Knows routine + variant + round + set | Just exercise name | If you build it | Full context |
| Heavy/light day variants Same exercise, separate progress tracking | No | Manual | Built-in |
| Start training immediately No account, no email, no waiting | Signup required | Yes | Instant |
| Blocks, circuits, supersets Organize exercises with structure | Basic | DIY | Full control |
| Works in any gym Full offline functionality | Limited offline | Yes | 100% offline |
| Zero distractions No social feeds, no influencer content | Social features | Yes | Training only |
The difference? Other apps show what you lifted last time you did "bench press." Serkit shows what you lifted last time you did bench press in this routine, on this variant, in this round, for this set. That's how you actually progress.
