LuKul separates the training loop into focused surfaces: plan the work, log the session, read the progress, and keep coaching oversight connected.
[WORKOUT PLANNER]
Plan the block before execution.
Build days, exercises, set protocols, and training intent before the session starts.
[WORKOUT LOG]Capture the set while it is alive.
Log load, reps, RPE, notes, rest, and completed work inside the live session runtime.
[PROGRESS TRACKER]Turn completed work into history.
Review progression, readiness context, strain, macro-cycle movement, and private training records.
[COACHES]Keep coaching oversight connected.
Support planning freedom, client logging, and coach-aware review without losing the training thread.
// FAILURE MODE
Progress breaks when the training record fragments.
Useful training data has to survive beyond the session.
The plan, the logged work, the body's response, and the next decision need to remain connected across weeks. LuKul keeps those layers inside one training loop.
[PLAN DRIFT]
Planning loses contact with execution.
Training plans stay useful when the work performed in the room remains connected to the block.
[WEAK CONTEXT]
Session logs lose context.
Sets, loads, and effort become more useful when they remain tied to readiness, fatigue, and progression.
[DISCONNECTED BODY]
Recovery signals arrive too late.
Readiness and accumulated stress need a place inside the training record before the next session begins.
[FRAGMENTED HISTORY]
History becomes hard to use.
Months of work should become a decision layer with continuity across entries.
LuKul keeps the loop intact.
// CLOSED LOOP TRAINING
Plan. Log. Track. Decide.
[PLAN THE BLOCK]
Build the work before execution starts.
Create structured sessions, organize exercises, and align your work with a larger training block.
[EXECUTE THE SESSION]
Capture the session without turning training into admin work.
Record sets, reps, loads, cardio work, and notes while preserving flow.
[PRESERVE THE SIGNAL]
See the pattern behind the numbers.
Follow volume, intensity, readiness, completion, and performance trends across time.
[DECIDE FROM HISTORY]
Make the next decision from your record.
Use your own training history to understand where to push, where to stabilize, and where accumulated stress is starting to speak.
// USER PROFILE
Built for training that deserves a record.
[SERIOUS GYM USERS]
You already train consistently and want a system that respects the detail of your work.
[STRENGTH & HYPERTROPHY]
You care about progression, volume, load, fatigue, and repeatable execution.
[TRANSFORMATION CLIENTS]
You need structure, history, accountability, and clear direction across the training block.
[COACHES & PRACTITIONERS]
You need a workspace that can support real programming logic and client progress beyond a pretty checklist.
[DATA-CONSCIOUS ATHLETES]
You want useful training signals, private records, and a calmer way to understand your work.
Best fit when training already matters.

- You care about progression across weeks.
- You want structure without turning the gym into admin work.

// HUMAN ORIGIN
Built where coaching, code, and real bodies meet.

[COACHING LAYER]
Ljupka Ljubišević
Elite personal trainer / transformation architect.
The human coaching layer: training judgment, client transformation, program structure, recovery sensitivity, and the reality of what people can actually sustain.
[SYSTEM LAYER]
Miloš Kulpinski
CTO / system architect.
The technical layer: deterministic logging, private data structures, mobile runtime stability, sync logic, and the infrastructure required to make serious training data reliable.
LuKul exists because elite coaching needed software that could keep up with the standard of the work.
