Read tempo and pause notes in your training plan

A tempo note tells you how the phases of a repetition are timed. A pause note tells you where movement stops and for how long. Read these instructions beside the exercise name, sets, repetitions, and load; the timing numbers describe a different part of the plan.

For a four-part tempo, first identify the notation order. You can then connect each number to the movement phase it describes.

Decode the four tempo positions

ACE's April 2025 explanation of repetition tempo describes this order: eccentric phase, transition, concentric phase, transition. The eccentric phase involves the working muscle lengthening; the concentric phase involves it shortening.

ACE uses 4/0/2/0 as an example. In that notation, the durations are expressed in seconds:

The sequence concerns one repetition. It does not describe four sets or a two-minute rest. The example explains ACE's notation; your own plan supplies the assigned tempo.

Connect tempo order to the actual movement

The first movement you perform is not always the first phase listed in a tempo code. A bench press starts its repetition by lowering the bar. A conventional deadlift from the floor begins by raising it. A code that lists eccentric first still names phases in that order.

To read the code, match each movement to its phase. Avoid treating the four numbers as an automatic countdown beginning the moment you touch the equipment.

Use a demonstration of the named exercise to point out each phase and transition. If a letter replaces a number, keep the program's definition beside it. A symbol such as a letter cannot be assigned a duration from the numeric example alone.

Make a pause instruction complete

A pause note needs both location and duration. “Two-second pause” gives a time but leaves the point in the movement unresolved. “Pause at the named position for two seconds” identifies both when the position has been defined.

Here is a hypothetical clarification exchange:

Program entry: Paused variation, two seconds.

Question: “Which position should be held, and does the note apply to every repetition?”

Record after the reply: Exact position stated by the coach; two-second pause; applies to each repetition in this entry.

The completed record stays beside the exercise. It prevents a pause instruction from becoming a separate message you must search for between sets.

Distinguish planned tempo from observed speed

A repetition that looks slow on video does not show what timing the program assigned. Keep the written tempo in one field and any observation in another.

For example: “Assigned tempo: as written in program version 2. Observation: final repetition appeared slower than the earlier repetitions.” The observation can be discussed without silently changing the exercise label to “tempo work.”

Likewise, retain a pause label when comparing sessions. A record that omits the pause loses part of the task, even if the weight and repetition count match.

Keep tempo beside the full exercise instruction

Save the exercise variation, tempo or pause, load, and assigned work in the same readable entry. The sets-and-reps guide explains the numeric fields around the timing note.
