Sproing Fitness: What Happened After Shark Tank

Sproing Fitness: What Happened After Shark Tank

Embarking on the innovative journey paved by founders Steve Lenz and Paul Toback, Sproing Fitness entered the spotlight on Shark Tank, unveiling its groundbreaking running machine. Now, post-Shark Tank, this article delves into the compelling narrative of Sproing Fitness, exploring the evolution of the company and its revolutionary fitness concept.

From its distinctive features to the impact on joint health and the incorporation of High-Intensity Interval Training (HIIT), discover the transformative path this fitness solution has traversed since its television debut, unveiling the highs, the challenges, and the ultimate success story of Sproing Fitness in the post-Shark Tank landscape.

What Is Sproing Fitness:

Sproing Fitness revolves around a proprietary air-cushioned treadmill, designed to provide High Intensity Interval Training (HIIT) without the harsh impact associated with traditional treadmills. This innovative design aims to boost strength and endurance, particularly for runners, who can benefit from the reduced strain on their joints [1].

The air-cushioned treadmill is a significant departure from standard fitness equipment. By reducing the impact on the user’s joints, it allows for a more comfortable workout experience. This is a major selling point for runners, who often struggle with joint issues due to the high-impact nature of their sport.

What Is Sproing Fitness

The Unique Concept And Design

The Sproing Fitness machine distinguishes itself by providing users with a uniquely spongy and soft surface, reminiscent of a trampoline. Equipped with integrated resistance bands and a securing belt, the machine encourages the correct running position — leaning forward and landing on the forefoot rather than the heel, thereby minimizing impact and ensuring a low-impact workout experience.

This design allows individuals to train with increased intensity while landing softly, alleviating concerns about falling or attempting to match the pace of a moving treadmill belt [2].

Supported by research conducted by Benedictine University’s Department of Physiology, the Sproing Fitness machine demonstrates remarkable benefits. The study revealed a substantial reduction in impact on various joints, with a 50% decrease on the knees, 32% on the ankles, and 41% on the back. This reduction in impact positions Sproing Fitness as an appealing option for individuals seeking a joint-friendly exercise solution.

Moreover, the customizable nature of the soft surface enables users to tailor the degree of cushioning and level of challenge, making it suitable for individuals of all ages and fitness levels, from beginners to elite professional athletes. Short bursts of high-intensity exercise become accessible to everyone, promising impressive results.

In addition to its innovative design, Sproing Fitness has pioneered the development of High Intensity Interval Training (HIIT). This workout regimen incorporates intervals of both high-intensity cardiovascular exercise and strength and power exercises.

A typical 45-minute Sproing Fitness class comprises a 10-minute warm-up followed by 30 minutes of intense interval training. These high-intensity intervals, characterized by short bursts of vigorous exercises, contribute to maximum fat burning, muscle toning, and overall body conditioning.

The integration of HIIT further solidifies Sproing Fitness as a comprehensive and effective fitness solution, offering a time-efficient approach to achieving fitness goals.

Key Features:

Low-Impact Design:

One of the standout features of Sproing Fitness is its emphasis on low-impact exercise. Traditional running on a treadmill can place significant stress on joints, particularly the knees. Sproing, on the other hand, incorporates a soft, cushioned surface that reduces impact, making it an appealing option for individuals with joint issues or those looking for a gentler workout alternative [3].

Treadmill and Strength Integration:

Sproing merges cardio and strength training seamlessly, offering a comprehensive full-body workout. The equipment includes a treadmill-like surface combined with resistance bands, allowing users to engage in both running and strength exercises in a single session. This integration appeals to individuals seeking efficiency in their workouts, as it eliminates the need for separate cardio and strength training sessions.

Adjustable Resistance:

To cater to users with varying fitness levels, Sproing Fitness incorporates adjustable resistance settings. This feature enables beginners to start at a manageable level and progressively increase intensity as their fitness improves. Advanced users, meanwhile, can push themselves to higher resistance levels for a more challenging workout.

Engaging and Interactive Workouts:

Sproing Fitness aims to make exercise enjoyable by incorporating interactive elements. Users can engage with virtual trainers, follow pre-programmed workouts, and even compete with others in a gamified environment. This adds an element of fun and motivation to the fitness routine, making it more likely that users will stick to their exercise regimen.

Joint-Friendly Exercise:

The low-impact design of Sproing Fitness is a game-changer for individuals with joint concerns. The soft surface minimizes stress on joints, making it an excellent choice for those recovering from injuries or dealing with chronic joint conditions. This feature sets it apart from traditional treadmills and other high-impact cardio equipment.

Efficient Full-Body Workout:

The integration of cardio and strength training in one machine is a major advantage. Sproing Fitness offers a time-efficient solution for individuals with busy schedules, eliminating the need for separate cardio and strength sessions. This can be particularly appealing to those who prefer shorter, more intense workouts.

Customizable Resistance Levels:

The ability to adjust resistance levels makes Sproing Fitness accessible to a wide range of users, from beginners to seasoned fitness enthusiasts. This adaptability ensures that individuals can tailor their workouts to match their current fitness levels and progressively challenge themselves over time.

Interactive and Motivational:

The interactive features, including virtual trainers and gamified elements, contribute to a more engaging workout experience. This can be a significant motivator, especially for individuals who find traditional exercise routines monotonous. The competitive aspect adds a fun and social dimension to the fitness journey, potentially fostering a sense of community among users.

Compact Design:

Unlike bulky home gym equipment, Sproing Fitness boasts a relatively compact design, making it suitable for home use without occupying excessive space. This is a practical advantage for individuals with limited workout space or those looking for a home fitness solution that doesn’t dominate their living area.


Cost Considerations:

One of the primary drawbacks of Sproing Fitness is its relatively high cost compared to traditional treadmills or other home fitness equipment. The initial investment might be a deterrent for budget-conscious consumers, especially when there are more affordable alternatives available.

Learning Curve:

Transitioning to the Sproing Fitness system may involve a learning curve for some users. The unique design and combination of running and strength elements may take time to get accustomed to, potentially leading to initial discomfort or a less fluid workout experience.

Limited Availability:

As of 2023, Sproing Fitness might not be widely available in all regions. This limited availability could pose challenges for individuals interested in trying the product, particularly if no local facilities or gyms are offering Sproing Fitness sessions.

Maintenance Requirements:

The soft surface of the Sproing Fitness equipment may require more maintenance compared to traditional treadmills. Regular cleaning and inspection to ensure the integrity of the cushioned surface are essential for optimal performance. This additional maintenance might be a consideration for users seeking low-maintenance fitness equipment.

Dependency on Technology:

The interactive and virtual elements that enhance the Sproing Fitness experience may be a double-edged sword. Users who prefer a more straightforward, technology-free workout may find these features distracting or unnecessary. Additionally, any technical issues with the interactive components could disrupt the user experience [4].

About Founders Of Sproing Fitness

The ingenious Sproing Fitness machine, launched by Paul Toback and Steve Lenz, emerges as a solution aimed at mitigating workout-related injuries. Replacing the rigid wooden deck of the treadmill, the Sproing integrates a shock-absorbing air cushion, replicating the experience of running on a beach. Additionally, the device incorporates a tethered rope, allowing users to fasten it around their waist, thus simulating the natural falling angle experienced during outdoor running [5].

Initiating Sproing Fitness, the company responsible for manufacturing and retailing the innovative Sproing device, Paul and Steve draw upon their extensive running background. Both passionate runners themselves, encountered the challenges faced by fellow enthusiasts, serving as the impetus for the development of the Sproing device.

Paul, with a previous role as the CEO of Bally Total Fitness, and Steve, formerly the head of engineering at Life Fitness, combine their expertise to introduce a groundbreaking running device, marking the first innovation in this domain in a century. In a fitness landscape dominated by traditional options like treadmills, ellipticals, steppers, stationary bicycles, and rowers, the Sproing stands as a pioneering addition.

About Founders Of Sproing Fitness

Sproing Fitness stands out as a brand specializing in the distribution of the Sproing, a cutting-edge running apparatus designed to enhance running performance by optimizing body positioning during exercise. While treadmills remain among the most widely favored running machines, they often fall short of adequately aligning runners for optimal performance.

Typically, individuals tend to lean forward as they run, a natural inclination. However, conventional treadmills prompt users to land with their legs first, subjecting the ankles, knees, hips, and back to excessive pressure, ultimately contributing to a high incidence of injuries. Shockingly, a staggering 85% of runners face injuries annually, with poor posture identified as a primary culprit [6].

Initially launching their products independently, Paul and Steve took a proactive step by establishing fitness studios where individuals could engage in workouts featuring the Sproing device. Recognizing the need for additional capital and sales acumen to fuel their expansion, they sought an opportunity on Shark Tank. Their application successfully navigated the selection process, leading to an invitation to feature on the 9th episode of the 10th season of the renowned show.

The Pitch Of Sproing Fitness At Shark Tank

In their appearance on Shark Tank, Paul and Steve entered the proverbial shark-infested waters seeking a $ 500,000 investment in exchange for an 8% stake in their company, Sproing Fitness. Their pitch began with a presentation showcasing the innovative Sproing device, inviting some of the sharks, namely Daymond and Robert, to experience its effectiveness firsthand. Both Daymond and Robert found the Sproing to be a powerful fitness tool [7].

Paul seized the opportunity to elaborate on the fitness classes offered, emphasizing the potential to burn 1000 calories in a 40-minute workout. 

However, skepticism arose from Kevin, who questioned the inability to purchase only the mat without additional accessories. Paul clarified that the initial purchase could be limited to the mat, with the option to gradually incorporate more elements for an enhanced workout experience. Kevin, content with the response, pivoted to inquire about the pricing.

Paul revealed that the Sproing retailed at $ 6,499, prompting the sharks to express reservations about its relatively high price. Undeterred, Paul drew on his experience as the former CEO of Valley Fitness, asserting that there was nothing comparable in the market. Lori sought the insights of Robert and Daymond, both of whom acknowledged the device’s effectiveness and intensity.

Paul revealed their expansion plans, indicating the establishment of studios. As the sharks probed into the sales model, Paul disclosed encountering resistance after reaching the $ 1,000,000 sales mark. Kevin attributed this resistance to a lack of belief in the device, prompting Paul to highlight Steve’s extensive patents for treadmills and ellipticals as an impetus for their independent venture.

Mark Cuban delved into the customer demographic, learning that Sproing Fitness garnered significant sales from rehab centers and private training studios. The slow uptake prompted the duo to open four studios in their hometown, Chicago. When Kevin inquired about the profits from these studios, Paul disclosed $ 400,000 in sales. The sharks then learned that Paul and Steve had invested approximately $ 2,000,000 in Sproing Fitness.

However, the tide began to turn as Kevin expressed doubt about the product’s success, deeming it a “dog” in terms of sales performance. He predicted an eventual shutdown for Sproing Fitness. Mark Cuban, sensing the familiar trajectory of such fitness studios, exited the deal, citing the challenge of sustaining interest as novelty waned.

Lori and Daymond followed suit. Lori deemed the product not broad enough, while Daymond emphasized the need for consumer education for Sproing Fitness to thrive, a task he deemed challenging. Robert joined the exodus, citing the perceived lack of progress. Finally, Kevin, lacking confidence in the product, made his departure.

Left without an offer, Paul and Steve exited the tank with disappointment. Paul expressed regret that the sharks failed to recognize the product’s potential, asserting that Sproing Fitness was poised for upward scaling, envisioning it as a company destined for greatness. Despite the setback on Shark Tank, the duo remained determined to pursue their vision for Sproing Fitness [8].
