A line such as 2 × 8–10, rest 90 seconds is a compact set of instructions. It does not tell you everything you need to perform an exercise, but you can decode it before you pick up a weight. Read the exercise name, the amount of work, the load or effort instruction, and the rest instruction as separate pieces.
This guide is a reading tool, not a workout prescription. The numbers below are invented examples. Use the instructions appropriate to your own plan, and ask its author about missing information rather than filling gaps with somebody else's routine.
Start with the units
A repetition is one complete performance of a movement; a set is a group of repetitions. The CDC explains these basic strength-training terms.
- Reps: how many repetitions appear in one set
- Sets: how many groups the instruction asks you to perform
- Load: the resistance, with its unit or equipment setting
- Rest: the pause between the specified sets or exercises
- Per side: the stated work applies separately to each side
- Seconds or minutes: a duration, which is different from a repetition count
Units prevent surprisingly large misunderstandings. A number beside a dumbbell exercise might refer to each dumbbell, while a barbell entry might refer to total weight. A number on a machine may be a setting rather than pounds. If the card does not explain the convention, ask before using it.
Decode an example workout card
Fictional instruction: Seated row, 2 × 8–10; load chosen with instructor; rest 90 seconds between work sets. Practice set listed separately.
- Identify the exact exercise. “Seated row” is a name, not a demonstration. Confirm the intended equipment, setup, and movement with someone qualified to teach it.
- Read the first number. The 2 means two work sets in this example. It does not mean two exercises or two minutes.
- Read the range. Each work set has a target of eight to ten repetitions. The card's range is not permission to force a repetition after control is lost.
- Check the load field. It is deliberately unresolved here. You cannot calculate the correct weight from the repetition range alone.
- Locate the pause. The example places 90 seconds between the two work sets. It does not say that you must restart despite feeling unready.
- Separate preparation from work. Because this card lists a practice set separately, its two work sets come afterward. Other plans may use different bookkeeping.
The arithmetic is sixteen to twenty planned work repetitions: two sets multiplied by eight to ten. That total is useful for reading the card; it is not a score you must achieve at any cost.
Translate a complete line into ordinary language
Do not stop after decoding the numbers. Read the whole assignment as a sentence: “I will use this exercise version, complete this amount of work under this effort instruction, pause here, and record what happened.” If you cannot fill one part, keep that part visibly unresolved.
For someone starting at a new facility, the exercise version is often the missing piece. Book a Gym of Foley tour to ask about available equipment and how appropriate instruction can be arranged. A name on a workout card does not confirm that a particular device is present or that a tour includes coaching.
Work through a per-side example carefully
Fictional reading exercise: A card says “2 sets of 6 repetitions per side” and explicitly instructs the reader to finish one side before the other. Under that wording, each side has twelve planned repetitions across the two sets. Across both sides, the arithmetic is twenty-four. Those totals describe the notation only; they do not make this an appropriate assignment for you.
Now suppose the card instead says “12 alternating repetitions total,” with one side followed by the other and six counted on each side. That is a different instruction from twelve per side. If the words “total” and “per side” are absent, ask. Do not double the assignment to be safe, and do not halve it based on a guess.
Rest still needs its own explanation. Does the pause occur after each side, after both sides, or after a larger sequence? The repetition arithmetic cannot answer that. Write the clarified sequence in full once before using shorthand in your log.
Distinguish rounds from straight sets
Another fictional reading example: A plan names A1 and A2 and states that one round consists of one assigned set of A1 followed by one assigned set of A2, with pauses specified separately. Completing two rounds means completing the pair twice: two A1 sets and two A2 sets. It does not mean four sets of each.
By contrast, an instruction to finish all A1 sets before starting A2 describes a different sequence. Neither sequence is established by the letters alone. The plan's key must identify the order, transitions, pauses, and stopping cues.
If the fitness planner is your starting reference, read its explanations alongside the numbers. It provides general educational guidance within its displayed limits, not live technique coaching or medical clearance. Ask a qualified professional about unclear movements before trying them.
Check the record against the assignment
Keep planned work and completed work in separate fields. A line that prescribed two sets does not prove both occurred. If you completed one, write one and explain the relevant reason. That lets the next review use what actually happened rather than a copied template.
- Plan: exact exercise, units, set count, repetition or time target, pauses.
- Actual: completed work and equipment used.
- Difference: what changed and why.
- Question: what needs clarification before repeating the task.
Do not confuse duration with repetition count
“2 × 20 seconds” means two timed efforts under that plan's instructions. It does not mean twenty repetitions. Check how to enter and leave the position, how to breathe, and when to stop. A duration alone cannot teach the movement.
Copy this clarity check into your plan
- Exercise and exact version: _____
- Setup or demonstration I still need: _____
- Work sets, repetitions, or duration: _____
- Resistance and its units: _____
- Effort or stopping instruction: _____
- Rest placement and duration: _____
- Practice sets counted separately? _____
- Alternatives approved for this plan: _____
A completed card should be understandable in plain language. Try saying it aloud once without abbreviations. Any part you cannot explain becomes a question for the plan's author, rather than a guess during the session.

Sets and reps FAQ
Does a repetition range tell me which weight to use?
No. The load or effort instruction is separate. Do not calculate a personal weight from the count alone.
Should practice sets appear in my record?
Label them according to your plan so they are not confused with work sets or silently added to the assignment. If the plan does not explain its convention, ask.
What if an app and my instructor use different abbreviations?
Use a written key that makes the actual instruction clear. Matching abbreviations matters less than understanding the same movement, amount, sequence, and stopping rule.
