Tempo - Execution speed
Tempo - Execution speed
Definition
Tempo is the controlled execution speed of each phase of a rep. Notation: 4 numbers like "3-1-1-0" representing eccentric / pause down / concentric / pause up, in seconds.
💡 Two people doing the same exercise with the same load can have radically different stimuli depending on tempo. It's an underestimated variable.
How tempo notation works
| Position | Phase | Example (Squat) |
|---|---|---|
| 1st number | Eccentric (lengthening) | 3 sec descent |
| 2nd number | Pause low | 1 sec at the bottom |
| 3rd number | Concentric (shortening) | 1 sec ascent |
| 4th number | Pause high | 0 sec at the top |
Example tempo "3-1-1-0" on a squat: 3 sec down, 1 sec pause, 1 sec up, no pause at top.
Benefits of controlled tempo
- ✅ Increases time under tension: more stimulus per rep
- ✅ Better mind-muscle connection: feel the muscle working
- ✅ Cleaner technique: no momentum, no cheating
- ✅ Reduces injury risk: better control
- ✅ Develops weak ranges: pauses target specific angles
Optimal tempos by goal
| Goal | Recommended tempo |
|---|---|
| Maximum strength | 2-1-X-0 (X = explosive) |
| Hypertrophy | 3-1-1-0 or 4-0-1-0 |
| Power / explosiveness | 1-0-X-0 |
| Technique / rehab | 4-2-3-1 |
| Drop the ego | 5-0-2-0 |
The crucial role of the eccentric phase
Slowing down the eccentric (3-5 sec) is the simplest way to increase the stimulus without changing the load:
- Recruits more muscle fibers
- Creates more micro-trauma (good for hypertrophy)
- Improves overall control
- Lowers injury risk
Common mistakes
- ❌ Letting the load drop free (no eccentric control)
- ❌ Using momentum to lift
- ❌ Skipping pauses on tempo prescribed with pause
- ❌ Always having the same fast tempo, no variety
- ❌ Counting in the head too quickly (1 sec ≠ 0.3 sec)
Key takeaways
Tempo is a free intensification tool. Slow down your eccentric (3 sec minimum), control the bottom, drive up with intent. Same load, very different stimulus. Don't underestimate it.
