The Four-Vector Model
5bar is built on one conviction: strength must transfer across movement. Isolated outputs — heavier lifts in a vacuum, bigger muscles without control — are noise. Real capability holds up across planes, patterns, and real-world conditions.
5bar trains the body as a multi-directional system, not a collection of parts.
Every session is scored against four fixed vectors. They define what progress means and keep every workout accountable.
| Vector | Measurement | Unit |
|---|---|---|
| Strength | Peak load expressed through movement planes | kg |
| Endurance | Total session volume (sets × reps × weight) | kg |
| Efficiency | Volume delivered per minute of work time | kg/min |
| Mobility | Control, range, and symmetry of movement | Quality rating |
Most programs chase effort. 5bar chases transfer, balance, and measurable capability.
Endurance without efficiency is wasted.
Mobility without strength leads to collapse.
The four vectors force a conversation between load, time, control, and resilience — keeping the system honest.
Every exercise is assigned to exactly one movement plane. No overlap, no ambiguity — just clear coverage across the body's fundamental patterns.
| Plane | Purpose | Examples |
|---|---|---|
| Push | Horizontal pushing | Push-ups, Bench Press |
| Pull | Horizontal pulling | Rows, Pull-ups |
| Press | Vertical pushing | Overhead Press, Lateral Raises |
| Hinge | Hip hinge pattern | Deadlifts, Swings, Cleans |
| Squat | Bilateral squat | Goblet Squats, Front Squats |
| Side Squat | Lateral work | Cossacks, Side Lunges |
| Twist | Rotational control | Windmills, Turkish Get-Ups |
| Run | Locomotion | Sprints, Running |
- Every exercise belongs to one plane — no dual classification.
- Every workout must contribute measurably to at least one vector.
- No filler metrics or arbitrary movements.
- Consistency enforced through repeatable, comparable measurement.
These constraints exist to keep training clear, honest, and comparable over time.
5bar is not a library of workouts. It is a training system that listens, learns, and adapts.
- Every session is run through a stress profile across vectors.
- Goals and equipment context steer the next cycle.
- AI-powered coaching keeps recommendations aligned with your direction.
Every recommendation is traceable, measurable, and directed toward transferable capability — not arbitrary effort.
Movement that holds up.
Capability that scales.
The goal is not to optimise one metric but to build the system that produces reliable movement.
