Just go outside and run. Or go even further than running. This is why sprinting will get you a ripped physique.
We talked about running before and how doing it only once a week will already change your body. But now we are digging deeper into something similar, but that has the potential to tap into other health and fitness benefits: we are talking about sprinting.
Sprinting and running differ mainly in intensity and duration. Sprinting involves short, high-intensity bursts where athletes run at maximum speed for brief periods, typically up to 60 seconds, engaging anaerobic energy systems and fast-twitch muscle fibres for speed and power. In contrast, running is a sustained, lower-intensity exercise that relies on aerobic energy systems and slow-twitch muscle fibres, focusing on endurance and stamina over longer distances. Thus, sprinting is geared towards explosive power, while running emphasizes maintaining effort over time.
Sprinting stands out as a pinnacle exercise not only for elite athletes but also for anyone looking to elevate their fitness regimen. Renowned for its intensity and the remarkable efficiency with which it sculpts the body and boosts performance, this dynamic activity offers a wealth of benefits that extend beyond the track.

And today you clicked on this link because you want to know why sprinting will get you a ripped physique. Or perhaps, you didn’t even know that is possible, but certainly is what Adam Sinicki is vouching for in a recent video.
Adam Sinicki is known online as “The Bioneer.” He is a health and fitness writer, and a personal trainer and has gathered almost one million subscribers on his YouTube Channel.
Sprinting challenges the body in a way few other exercises can, engaging multiple muscle groups and tapping into the body’s innate power and speed. As we delve deeper into the mechanics and benefits of sprinting, it’s clear why incorporating this vigorous form of exercise into your routine can lead to substantial improvements in both physical prowess and overall health.

Why Sprinting Will Get You a Ripped Physique
Sprinting is a powerhouse activity that targets nearly every muscle group, making it a superior full-body workout. It’s not just about the legs; when you sprint, your body engages in a highly dynamic movement that involves your core, arms, and even your shoulders. This full-body engagement results from the intense and rapid pumping of arms and the robust strides, which require a harmonious work of the pecs, shoulders, and back.
Hormonal Response and Muscle Building
Sprinting is not only a physical challenge but also a potent stimulator of hormonal responses crucial for muscle development and overall health. When engaging in high-intensity exercises like sprinting, the body experiences a significant increase in key hormones such as testosterone and growth hormone. Adam Sinicki, a fitness expert, points out that “one study it was actually found that sprint training could increase growth hormone production by 2,000%, which is absurd.” This surge in growth hormone is essential not only for muscle synthesis and repair but also offers benefits such as improved longevity and faster recovery.

However, it’s important to recognize that these hormonal spikes are transient. They provide a temporary boost that, while beneficial for accelerating muscle growth and enhancing recovery times immediately post-exercise, does not last long. Continuous and regular training is required to see long-term muscle-building results. Sinicki further explains that while sprinting triggers these hormonal increases, “it’s a transient benefit…it doesn’t stick around,” indicating that the lasting effects on baseline hormone levels are limited. This transient nature means that while sprinting can significantly enhance muscle building in the short term, consistent training is essential for sustained benefits.

Fast and Slow Twitch Muscle Fibers
Sprinting uniquely targets both fast and slow twitch muscle fibres, making it an exceptionally comprehensive form of exercise for improving various aspects of physical fitness. Fast twitch fibres are crucial for performing quick, powerful movements such as sprinting and jumping. These fibres are larger and provide short bursts of speed and power. By engaging these fibres, sprinting helps build muscle mass and increase strength and speed.
On the other hand, slow twitch fibres are endurance fibres, supporting activities that require endurance over long periods. Sinicki explains, “due to something called Henneman’s size principle, sprinting will train all of your slow twitch fibre as well as your fast twitch fibre.” This principle states that muscle fibres are recruited from the most to least forceful, meaning even the endurance fibres are engaged during intense activities like sprinting.
This dual engagement is a significant advantage of sprinting, as it ensures a comprehensive workout that enhances both speed and endurance capabilities. As Sinicki highlights, “when people say [sprinting] only targets fast-twitch fibre, it’s kind of a misnomer.” This multifaceted fibre recruitment makes sprinting not only effective for improving athletic performance but also for increasing overall muscle mass and enhancing metabolic rate through the activation of a larger spectrum of muscle groups.

Practical Tips for Effective Sprinting
To maximize the benefits of sprinting, incorporating specific training techniques and considerations can help:
- Start Gradually: If you’re new to sprinting, begin with shorter distances and gradually increase intensity to avoid injuries.
- Incorporate Drills: Use sprint drills to improve technique and efficiency. These can include high knees, butt kicks, and stride outs.
- Focus on Form: Proper sprinting form is crucial. Keep your arms at 90 degrees, push off the balls of your feet, and maintain a forward lean throughout the sprint.
- Recovery is Key: Allow adequate recovery between sprint sessions to prevent overtraining and enhance muscle repair.
- Combine with Resistance Training: While sprinting is effective on its own, combining it with resistance training can further enhance muscle growth and overall fitness.
Sprinting offers a unique combination of benefits, from enhancing muscle mass and improving hormonal health to boosting overall athletic performance. Whether used as a standalone workout or integrated into a broader training regimen, it’s an excellent way to achieve a variety of fitness goals. So next time you’re considering your workout options, remember that sprinting might just be the high-intensity, high-reward activity you need to elevate your fitness to the next level.
