It is a 12-exercise bodyweight circuit published in 2013 by Brett Klika and Chris Jordan in ACSM's Health & Fitness Journal. Each exercise runs 30 seconds with about 10 seconds of transition, totaling 7 minutes with no equipment. ### Is a 7-minute workout actually effective? As a high-intensity circuit it produces a real acute training stimulus, and the published rationale is solid, but a single 7-minute round is a minimum, not a complete program. Most guidance treats it as a daily baseline or a way to keep consistency on busy days. ### How do I time the individual exercises? The overall 7-minute timer above tells you when the whole session ends. For the 30-second work and 10-second transition blocks, use an interval app, count in your head, or follow a guided video that cues each change. ### What happens when the 7-minute timer hits zero? It rings and then starts counting up from zero until you dismiss it. If you run past the ring, the count-up shows how long the session actually lasted. ### Can I use a 7-minute timer for studying? Yes, as a quick-start sprint to break a procrastination loop or a flashcard review block. It is shorter than a classic study session, so most people chain two or three rounds with short breaks. ### Should I warm up before a 7-minute workout? A brief warm-up of one to two minutes of easy movement is recommended, especially before jumping jacks and squats. The published routine starts with jumping jacks partly to raise your heart rate, but cold joints still deserve a few easy reps first. ### Does the timer keep running if my screen locks? On desktop the countdown usually continues in a background tab. On mobile, some browsers suspend backgrounded pages, so keep the screen on and the tab visible for reliable exercise timing. ## Related tools - /eight-minute-timer/ - /six-minute-timer/ - /ten-minute-timer/ ## Sources - [High-Intensity Circuit Training Using Body Weight: Maximum Results With Minimal Investment (Klika & Jordan, 2013)](https://journals.lww.com/acsm-healthfitness/fulltext/2013/05001/high_intensity_circuit_training_using_body_weight.5.aspx) - [7-minute workout](https://en.wikipedia.org/wiki/7-minute_workout) --- *Local planning estimate.
