Short answer: Warm up for three minutes, complete two six-minute alternating blocks and use the final minute to cool down. Choose easy-to-moderate variations.
Who this workout is for
This routine suits busy days and small spaces. It is not meant to compress an advanced strength session into frantic intervals. For more volume, use the 30-minute workout.
The workout
| Exercise or block | Sets and reps | Focus |
|---|---|---|
| Minutes 0–3 | Warm-up and easy rehearsal | Continuous |
| Minutes 3–9 | Push-up, row, squat | 30 sec work / 30 sec transition |
| Minutes 9–14 | Lunge, bridge, dead bug | 30 sec work / 30 sec transition |
| Minute 14–15 | Walk and breathe | Easy cooldown |
| Optional | Repeat later, not immediately | Preserve recovery |
How to perform the session
Use a timer and stop each work period before form changes. Secure the row setup before the clock begins. Fewer clean repetitions are better than rushed partials.
How to progress
Increase repetitions within the same intervals or choose slightly harder leverage. Do not lengthen every work period at once. The home workout offers untimed alternatives.

It is enough for a useful short session, especially when performed consistently, though advanced strength work may need longer rests.
Should a 15-minute workout be HIIT?
No. It can use controlled strength circuits without maximal intensity.
