What Does DPS Mean in a Swim Workout?
DPS means distance per stroke: how far you travel with each swimming arm pull. In a workout, it is an efficiency focus, not a separate swimming style or an instruction to swim as slowly as possible.
How do you count DPS in the pool?
Divide the distance swum by the number of swimming strokes counted over that distance. For example, 25 metres divided by 20 hand entries gives 1.25 metres per entry. This whole-length estimate includes travel from the wall, so it is not a precise measurement of propulsion from your arms alone.
Illustrative poolside note: “25m pool, hand entries, 50m in 55 seconds, counts 20/21.” That tells you more than “DPS improved.” For the rest of a written set, see the swim workout reading guide.
How is DPS different from stroke count and SWOLF?
Stroke count is the number of swimming arm actions; DPS expresses distance per counted action. SWOLF adds swimming time in seconds to the count over a chosen distance. Keep that distance and counting method fixed when comparing scores.
Three views of the same swim
| Stroke count | DPS | SWOLF | |
|---|---|---|---|
| Calculation | Count arm actions | Distance ÷ count | Seconds + count |
| Example: 25m, 20 entries, 25 seconds | 20 entries | 1.25m per entry | 45 |
| Includes time? | No | No | Yes |
USMS illustrates the trade-off with a swim-golf calculation over 50: 30 arm actions plus 38 seconds scores 68; 28 plus 42 scores 70. The lower count came with a slower swim. Our SWOLF explainer covers that metric in more detail.
Which measure should you use?
For a DPS set, track count and pace together.
Use the count as a technique cue and the clock as a check. SWOLF combines them, but keeping both numbers visible makes the trade-off easier to understand.
What does a DPS set look like?
USMS uses short freestyle repeats to establish a count, then longer repeats to hold it while making the interval. These are AquaPlan example blocks adapted from that approach, not a complete session or a tested programme. Choose one after your usual warm-up; the fixed rests and drill-block repetition count below are editorial choices.
DPS freestyle: establish a repeatable count
Example main set — consistent push-offs and pace · 500m total
- 10 × 50m DPS freestyle — TU · Rest 20s between repeats · Swim at a comfortable, repeatable pace. Count each 25m separately and record the 50m time. Keep the same push-off distance; do not pause to force a lower count.
DPS freestyle: hold the count over longer repeats
Example main set — carry the same rhythm through each length · 500m total
- 5 × 100m Hold freestyle count and pace — TU · Rest 25s between repeats · Use your repeatable count from shorter swims as a reference, not a compulsory ceiling. Count each 25m and note the 100m time. Keep the arm rhythm moving.
For a drill/swim block, USMS describes the hip thumb-swipe as a cue for finishing the freestyle pull. Practise that cue, then carry it into normal swimming. These examples use a 25m pool; a 25-yard pool needs yard units, and drill/swim by 25 requires adaptation in a 50m pool.
DPS drill into normal freestyle
Example technique block — 25m drill, then 25m swim · 200m total
- 4 × Drill then swim — Rest 20s between rounds
- 25m Hip thumb-swipe drill — TU · Lightly brush the thumb past the hip at the end of each pull. Continue directly into the swim length.
- 25m Normal freestyle with DPS focus — TU · Keep a continuous rhythm and count hand entries. Carry the finishing cue into normal swimming without adding a glide pause.
Open a block in the AquaPlan workout builder to edit repeat distances, rest and counting notes. Write your intended pace into the instructions, then compare the actual times at the pool.
What mistakes make DPS misleading?
Chasing fewer arm pulls can create a misleadingly low count if you add long glide pauses. USMS emphasises that DPS is only part of swimming speed: you also need to turn the arms over effectively.

Sources checked October 6, 2026. The USMS glossary supplies the definitions; the two training articles explain counting, example set structures and the pace trade-off. Limitations: this is a pool-training explanation, not individual coaching or first-hand testing. The examples do not establish a universal ideal count.
