You might not be as familiar with the term “isometric training,” but are likely aware of basic isometric exercises like the plank and wall sit. Unlike traditional weightlifting, which involves lifting and lowering weight, isometrics require maintaining a fixed body position without excess movement in your joints. This unique training style focuses on engaging and holding tension in to help build endurance, strength, and stability or potential correct muscular imbalances.
If you’re interested in this type of training, the Isophit Strength Kit can be a helpful tool that allows you to move beyond the basics and perform a wide variety of isometric exercises. With the Isophit, you can engage in an isometric squat, leg press, chest press, shoulder press, deadlift, triceps dip, biceps curl, and more. This versatility enables you to target multiple muscle groups and tailor your workouts to your current fitness level and specific needs.

A Quick Look at Isophit
The Isophit Strength Kit is designed with a singular focus—to make isometric training accessible, versatile, and effective for everyone from Olympic and professional athletes like four-time World Figure Skating Champion Kurt Browning to everyday fitness enthusiasts like yourself. Its creator, Brad Thorpe, saw the untapped potential of isometric training in building strength, stability, and injury resistance without the risk of joint pain and stress2 often associated with traditional weightlifting exercises such as the barbell back squat. Thorpe, who has spent years researching muscle activation, muscle strength, and isometric protocols, brought the Isophit to life to deliver a safe, efficient workout method for building muscle and enhancing performance1.
Unlike traditional gym equipment, which often relies on weighted resistance and dynamic movement, the Isophit is centered around static holds and controlled muscle tension. This focus on isometric exercises provides a potential advantage over conventional weightlifting and cardio equipment by allowing users to achieve muscle engagement without repetitive joint strain. With its sturdy frame and open adjustable support bar, the Isophit easily adapts to a variety of exercises, such as isometric Zercher squats, chest and shoulder presses, deadlifts, and core holds. This flexibility helps you target specific muscles, making it ideal for strength, rehabilitation, sports performance, or endurance training.
Compared to other isometric trainers, the Isophit stands out for its durability and ease of use, as many isometric tools aren’t intended for home use or can be difficult to set up. The brand also emphasizes portability and practicality, making it a solid choice for home gyms and training studios.

Workout Experience/Using Isophit
The Isophit Strength Kit offers a unique and effective isometric workout experience, impressing from the moment you unbox it. The setup is refreshingly straightforward—no tools, no complicated instructions, just a fully assembled unit that’s ready to use. At 93 pounds, the unit is on the heavier side, so you’ll want to take some care when setting it up in your personal training space. Smaller individuals may want to enlist the help of a second person to make this process easier.
That said, the substantial weight is an asset, providing the stability and sturdiness necessary for intense isometric holds. The solid construction also ensures the unit stays firmly in place during your iso workouts, delivering a secure and safe experience. Isophit also thoughtfully includes a small floor mat to protect indoor surfaces from scuffs and scratches, a small but highly appreciated detail. For these reasons, I rated the Isophit Strength Kit a 5 out of 5 for ordering, assembly, and setup.
My first experience with the Isophit Strength Kit was through their 30inThirty program, which introduced me to a full-body isometric workout. The program is structured around 45-second holds with just 15 seconds of rest between exercises, challenging me to maintain a high level of intensity across various movements such as the leg press, deadlift, shoulder press, plank, and more—targeting both large and small muscle groups which earned it a 5 out of 5 for versatility.
This workout was an excellent introduction to isometrics, offering a hands-on way to learn the kit’s ins and outs and all the movements it can support. However, holding an isometric contraction at maximum intensity for the full 45-second interval proved incredibly challenging. I had to pace myself and adjust the exertion level slightly to maintain each hold, as keeping full intensity for that long without breaks was almost impossible.
Additionally, with only 15 seconds of rest, I quickly realized the importance of efficiently adjusting the support bar between exercises. Initially, this felt a bit rushed, but with practice, I got much faster at making the necessary angle changes. This quick transition became second nature, adding a smooth rhythm to my workout as I progressed through each exercise.
If you’re considering the Isophit Strength Kit and the 30inThirty programming, you’ll be pleased to know that the first 10 programs in the 30inThirty series are included with your purchase. These initial programs provide a challenging and effective introduction to isometric training, offering a variety of exercises that help you build strength and master different isometric techniques right from the start.
While I believe the 30inThirty programming itself deserves a full 5-star rating, the 4-star score reflects the additional $300 cost required for the complete program, which may be a consideration for those already investing in a premium product.
Footprint and Portability
At 93 pounds, the Isophit’s weight supports stability but can be difficult to move alone. Fortunately, the kit’s compact, low-profile design and ability to fold make it easy to stow in a home gym space. This balance of sturdy construction and small footprint earned the Isophit a 4.5 out of 5 for this category, as it’s both durable and compact but may require assistance to move.
Durability and Construction
The Isophit Strength Kit’s construction quality is exceptional—its stability and durable build ensure that it remains secure even through intense isometric holds. I appreciated the thoughtful inclusion of a floor mat, which prevents scratches and further stabilizes the equipment. For durability and craftsmanship, the Isophit gets a 5 out of 5.
Ergonomics and Comfort
During subsequent workouts, the Isophit Strength Kit proved itself intuitive and user-friendly, especially with its adjustable angle settings from zero to 90 degrees in 15-degree increments. I found the ergonomic design dynamic enough to support a wide range of movements, with the 75-degree setting ideal for exercises like the Zercher squat, shoulder press, and biceps curl. Meanwhile, I switched to the highest 90-degree setting for leg presses and hanging core stabilizations and the 45-degree setting for planks and chest presses.
I did find that I needed to make small tweaks, like adding a yoga mat to help improve my comfort level during holds, resulting in a rating of 3.5 out of 5.
Technology and Convenience
A future enhancement that would significantly improve the Isophit Strength Kit’s utility would be the addition of force-tracking features to monitor progress in isometric training. Unlike traditional weightlifting, where you can visibly see strength improvements by adding more weight to the bar, isometric training lacks that immediate feedback mechanism. This absence of digital tracking makes it challenging to gauge progress in strength gains over time.
While the Isophit remains an excellent tool for building strength, its inability to provide real-time performance feedback limits your ability to measure improvements effectively, resulting in a 1 out of 5 for technology (aka smart features).
Isophit vs X3 Bar
X3 Bar
Product Highlights
- Up to 300 lbs of force
- Upgrade to up to 600 lbs
- Free workout program included
- No assembly necessary
Pros & Cons
Pros
- Can create up to 300 pounds of force (up to 600 if you get the Elite Band, sold separately)
- Free 12-week workout program with high-quality workout and nutrition advice
- Bar has great knurling
- No assembly necessary

- Only 1-year warranty for the bands
- Some complaints of the bands wearing down after only a few weeks
Bottom Line
A compact piece of strength training equipment that combines the best parts of resistance bands and barbells into one.
The X3 Bar, developed by Dr. John Jaquish, integrates the principles of variable resistance training through its use of high-quality latex bands, claiming to provide a superior muscle-building stimulus compared to traditional weightlifting. This portable system combines an Olympic-style bar paired with resistance bands, creating a compact workout solution that can generate up to 300 pounds of force (or 600 pounds with an optional elite band). Lifters appreciate its ability to mimic a wide range of exercises typically performed with a barbell, including squats, bench presses, and curls, all while being space-efficient enough to fit in your travel bag.
In contrast, the Isophit Strength Kit offers a distinct approach with its unique isometric training system. This type of training emphasizes producing maximum muscle tension while enhancing strength and stability without excess joint movement. Unlike the X3 Bar, which relies on variable resistance through band stretching, the Isophit kit ensures consistent tension regardless of the position of the lift, which can be beneficial for isolating muscle groups and improving strength through movements.
Overall, both the Isophit and X3 Bar are designed for users seeking a more traditional weight training experience with added safety features that eliminate the risk associated with free weights. Their low-profile designs and exceptional portability make them worthwhile investments, especially for those seeking to maximize their home or travel workouts.
However, it’s important to note that the Isophit is approximately three times the price of the X3 Bar, so you’ll need to evaluate which option aligns best with your budget and training goals.

I would only recommend the Isophit Strength Kit for individuals who are serious about integrating isometric exercises into their fitness routine.
After all, you don’t want a $1,650 investment sitting in a corner and collecting dust in your home gym. Ultimately, for those willing to invest in the benefits of isometric training, the Isophit Strength Kit is a high-quality option that can help enhance your strength, stability, and athletic performance.
