How Does the One & Done Workout Work?

The One & Done Workout emphasizes short, daily workouts. Instead of torturing yourself with extended workouts and spending hours at the gym, you can enjoy powerful results with just 7 minutes of hard exercise per day.

According to Meredith Shirk and the Svelte Training team, 7 minutes is all you need to enjoy powerful health and fitness benefits. After a few weeks of training for 7 minutes per day, you can lose weight, support cardiovascular health, and enjoy other benefits when done right.

Many Meredith’s recommended One & Done Workouts are based on the SIT principle or Sprint Interval Training. Here’s how Sprint Interval Training (SIT) works:

  • Give 20 seconds of your best effort (say, by sprinting)
  • Rest for 2 minutes
  • Repeat

To be clear, Meredith doesn’t require you to actually “run” or “sprint” to complete Sprint Interval Training workouts. She needs you to give maximum effort for 20 seconds – no matter what type of workout you’re doing. You can cycle hard for 20 minutes, for example, or lift weights.

In the One & Done Workout program package, you can discover Meredith’s best and most recommended workouts for sprint interval training.

Essentially, Meredith’s strategy is based on high-intensity interval training, also known as HIIT. HIIT has been extremely trendy in recent years, and growing evidence supports the use of HIIT for weight loss, cardiovascular health, fat burning, and other benefits.

What makes the One & Done Workout different from other HIIT workouts? Here’s how Meredith Shirk explains it:

“The One and Done Workout is a unique type of high-intensity workout where you give as much effort as you possibly can for 20 seconds and only 20 seconds. You start with a warm-up…then you put forth your best effort for 20 seconds only. You follow that by an active recovery period that allows your heart and muscles to calm down before reaching their limits. Then you do it again – for just 20 seconds.”

By repeating this workout several times, you get a 7-minute workout. You get the intensity of a longer workout packed into a 7-minute session. That means powerful benefits without extended time at the gym.

According to Meredith Shirk, each 7-minute workout activates metabolic multipliers, fat-burning hormones, and other beneficial forces inside your body:

“Each time you do a 20-second interval, you activate your metabolic multipliers and prepare your body to burn fat hard for at least 24 hours and up a possible 48 hours in some people.”

The workout sounds intense, but it’s ideal for people of all levels. It doesn’t matter how hard your maximum intensity is – as long as you’re working out at your maximum intensity for a 20-second period. Over time, your maximum intensity could become stronger as you get into better shape. However, you can start doing the One & Done Workout regardless of your fitness level.

Scientific Evidence for the One & Done Workout

There’s plenty of evidence supporting the use of high-intensity interval training. The One & Done Workout sales page cites several studies supporting the use of high-intensity interval training (HIIT) and spring interval training (SIT). HIIT and SIT are very similar to one another, and most studies use the two terms interchangeably.

This 2019 study published in the World Journal of Cardiology found that high-intensity interval training and spring interval training led to powerful health benefits, particularly in cardiovascular health. People who engaged in aerobic HIIT and SIT tended to have better cardiovascular health:

“For general health and primary and secondary cardiovascular prevention, high-intensity interval training (HIIT) has been recognized as an efficient exercise protocol with short exercise sessions.”

Is training for 7 minutes per day really better than training for 70 minutes per day? Is HIIT or SIT comparable to extended cardio sessions?

Researchers at the University of New Mexico sought to answer that question in this study. Researchers analyzed the body’s response to HIIT and continuous exercise. Researchers concluded that HIIT led to similar and often better improvements in a short period of time compared to lengthy, continuous exercise:

“For years, continuous aerobic exercise has been the chosen method to achieve these goals. However, research shows that HIIT leads to similar and in some cases better improvements in shorter periods of time with some physiological markers.”

Based on this analysis, researchers recommended incorporating HIIT into a client’s cardiovascular training to help with weight loss and cardiovascular health.

Do the benefits of HIIT and SIT last long term? Or are they just short-lived benefits?

In 2016, researchers analyzed the effects of sprint interval training (SIT) over a 12-week period. Researchers told participants to engage in continuous exercise or SIT. Participants performed 1 minute of intense exercise within a 10 minute time period (SIT) or 50 minutes of continuous exercise. After 12 weeks, researchers found that the two groups had similar improvements to cardiovascular health and endurance training – even though one group spent just 10 minutes exercising and the other group spent 50 minutes exercising.

In most of these studies, researchers advocated for a combination approach. It would help if you did not exclusively do continuous exercise, nor should you exclusively do HIIT exercise. By mixing your workouts, you can enjoy the benefits of each.

Overall, HIIT and SIT have been repeatedly proven effective in numerous studies, and it’s possible that 7 minutes of hard exercise per day could deliver similar benefits to extended cardio sessions.
