Tempo
Tempo is a four-digit code that sets the speed of each phase of a rep: eccentric (lowering), pause at the bottom, concentric (lifting), pause at the top. A tempo of 3-1-1-0 means three seconds down, one second pause, one second up, no pause.
Tempo: what is it?
Two clients can do the same exercise, the same weight and the same reps and get a different result, because one of them drops the bar and bounces while the other controls it. Tempo is how a coach writes that difference into the program. The four-digit notation makes rep speed explicit, which turns "control the weight" from a cue into a prescription that can be tracked and progressed.
How to read tempo notation
Each digit is a number of seconds. The order is always the same, and the first digit is always the eccentric, even on exercises that start with the lifting phase (a row, a pull-up, a biceps curl). An "X" in the concentric position means "as fast as possible".
| Digit | Phase | In 3-1-1-0 | Example: squat |
|---|---|---|---|
| 1st | Eccentric (lowering) | 3 seconds | Descending into the squat |
| 2nd | Pause at the end of the eccentric | 1 second | Holding the bottom position |
| 3rd | Concentric (lifting) | 1 second | Standing back up |
| 4th | Pause at the end of the concentric | 0 seconds | No pause at lockout, straight into the next rep |
Common tempo prescriptions
There is no single best tempo. The eccentric is where most of the control lives, so it is the digit coaches manipulate most. Pauses remove the stretch reflex and expose weak positions. The concentric is usually left fast or "X" because trying to lift slowly on purpose just means lifting less.
| Goal | Typical tempo | Why |
|---|---|---|
| Hypertrophy | 3-0-1-0 or 2-1-1-0 | Controlled eccentric, full range, no bouncing. |
| Strength | 2-0-X-0 or 1-0-X-0 | Controlled descent, maximal intent on the way up. |
| Power | X-0-X-0 | Speed in both directions, submaximal load. |
| Rehab and control | 4-2-1-1 | Slow, deliberate, pauses to own each position. |
| Technique learning | 3-1-1-1 | Time to feel and fix positions on every rep. |
What tempo changes and what it does not
Slowing the eccentric increases the time the muscle spends under load at long muscle lengths, which is useful for hypertrophy and for teaching control. Pauses kill momentum, so a paused squat or paused bench makes the lifter produce force from a dead stop, which is why they show up in strength programs as a variation.
What tempo does not do is replace load. A 5-second eccentric with a weight that is too light still produces an easy set. Tempo is a way of standardising how a rep is performed so that reps and load mean the same thing week to week; it is not a substitute for progressive overload.
Common mistakes
- Prescribing slow tempos on everything. A 4-2-2-2 curl is fine; a 4-2-2-2 heavy deadlift is a way to lift much less and get tired.
- Counting inconsistently. Clients count fast when the set gets hard. Have them count out loud in the first weeks, or use the rest timer beep as a metronome.
- Forgetting the first digit is the eccentric. On a pull-up, "3-0-1-0" means three seconds coming down, not going up.
- Chasing tempo on explosive lifts. Cleans, snatches, jumps and throws have one tempo: as fast as possible.
- Never progressing it. Tempo can be a progression variable too: 4-1-1-0 one block, 3-0-1-0 with more load the next.
Key takeaways
- Tempo is four digits in seconds: eccentric, bottom pause, concentric, top pause. The first digit is always the eccentric.
- The eccentric and the pauses are the levers; the concentric is usually fast or "X".
- Common prescriptions: 3-0-1-0 for hypertrophy, 2-0-X-0 for strength, 4-2-1-1 for rehab and control.
- Tempo standardises how a rep is done so load and reps stay comparable; it does not replace heavier weight.
Frequently asked questions
What does tempo 3-1-1-0 mean?
Three seconds on the lowering phase (eccentric), a one-second pause at the bottom, one second on the lifting phase (concentric), and no pause at the top before the next rep. On a bench press that is a 3-second descent, a 1-second hold on the chest, a 1-second press and straight back down.
Is a slower tempo better for muscle growth?
A controlled eccentric of 2 to 4 seconds helps most people get more out of a set, mainly by removing bouncing and momentum. Beyond that, going slower forces the load down and the set gets easier rather than more productive. Control the eccentric, lift with intent, and let load and effort drive the growth.
What does X mean in a tempo?
X stands for explosive: perform that phase as fast as possible with good form. It almost always appears in the concentric position, as in 2-0-X-0. The bar may not actually move fast when the load is heavy, but the intent to accelerate is what the X is asking for.
