The One and Done Workout is a quick, seven-minute routine that promises real results without the time demands or complicated moves you’d expect from a traditional workout.
The idea behind it is simple: it’s all about short bursts of high-intensity movement that trigger fat-burning hormones and boost metabolism.
What’s the Core Approach?
The One and Done Workout draws inspiration from Sprint Interval Training (SIT), a high-intensity method focusing on short, intense movements that are brief yet highly effective.
SIT relies on short bursts of energy, getting your heart rate up and then letting it settle. By repeating this pattern, you’re not only working your muscles but also stimulating hormone production that helps burn fat.
- 20 seconds of all-out movement (think sprinting or high knees)
- A short rest period to let your heart rate normalize
- Repeat cycle until you’ve hit the seven-minute mark
Yes, seven minutes—that’s it! Those short intervals might seem too brief to make a difference but don’t underestimate the impact. This targeted approach triggers your metabolism, promoting natural fat-burning even after you’ve stopped moving.
Most short workouts share a common promise—big results in little time—but the One and Done Workout approaches that goal differently from the routines you may already know. Traditional High-Intensity Interval Training (HIIT) blocks typically run 20–30 minutes and scatter multiple strength moves between rest periods; the classic “7-Minute Scientific Workout” crams 12 body-weight exercises into a single nonstop circuit; and Tabata protocol asks for eight rounds of 20 seconds on / 10 seconds off (a four-minute sprint in total). By contrast, One and Done relies on Sprint Interval Training principles that focus on a single, all-out 20-second burst, followed by active recovery, repeated until you hit the seven-minute mark.
Why does that matter? Whereas HIIT and Tabata emphasize calorie burn during the session, One and Done is calibrated to maximize the post-exercise “afterburn” through a sharper hormonal spike—especially in Human Growth Hormone (HGH) and catecholamines like adrenaline. In other words, the routine is built to keep your metabolism elevated after you’ve stopped moving, not just while you’re sweating.

The Session Structure
Let’s go through a typical One and Done session to see how it’s structured. Each session follows three main phases:
1. Warm-Up
To get your body ready, each workout kicks off with a quick warm-up. This doesn’t mean a full-blown stretching routine but enough to get your muscles awake and ready for the intensity to come. It’s all about preparing your body so you can go hard on those short intervals without risking injury.
2. The Active Period
Now comes the heart of the workout: 20 seconds of high-intensity exercise. During this short burst, you’re giving everything you’ve got. This phase is designed to get your heart racing, which not only burns calories but also activates key hormones. These hormones play a huge role in transforming your body into a “fat-burning machine” by keeping your metabolism elevated.
3. Rest and Repeat
After each 20-second burst, there’s a short rest period. This time isn’t about catching your breath completely but giving your heart a moment to return closer to normal. This active-rest cycle gets repeated multiple times until the seven-minute mark, keeping you engaged and maximizing calorie burn.
Unique Aspects of the One and Done Workout
There’s a lot that sets this workout apart from your typical high-intensity routines, especially in its approach to support the needs of women specifically.
It’s Designed with Women in Mind
Women have different hormonal cycles, energy needs, and, let’s be real, time constraints. By focusing on a hormone-activating approach, it supports metabolism in a way that aligns with female physiology.
The Hormone Angle—Fat-Burning Chemistry in Plain English
The workout uses specific movements to trigger hormone production, which not only helps with fat loss but also keeps your energy levels more stable. Think of it as lighting a match to get a fire going. You’ll feel the effects of these short workouts long after you’re done because those hormones stay active, promoting fat-burning well beyond your seven minutes of exercise.
So what exactly happens inside your body during those 20-second bursts? Two key players step in: Human Growth Hormone (HGH) and catecholamines (including adrenaline). When you push to near-maximum effort, your body releases HGH, sometimes nicknamed the “fitness hormone,” because it accelerates fat metabolism while preserving lean muscle. Simultaneously, catecholamines flood your system, telling stored fat to break down into usable fuel.
The impressive part is how long these chemical messengers linger. Research on sprint-interval protocols shows HGH can remain elevated for up to two hours post-workout, and metabolic rate can stay up to 15 percent above baseline for the next 24 hours. That means your seven-minute investment continues to pay dividends all day, even while you’re sitting at work or relaxing with family.
Joint-Friendly Movements
High intensity doesn’t have to mean high impact. The One and Done Workout includes moves that are gentler on your joints, making it suitable for women of various fitness levels. This joint-friendly design also makes it ideal if you’re someone who experiences joint discomfort or if you’re just not into high-impact movements. No burpees are required!
The owner of Mamasupps notes, “Short, high-intensity routines can still be gentle on joints—an approach especially helpful for those incorporating MamaSupps for prenatal fitness to maintain a safe, well-rounded exercise regimen.”
