Sorinex Back Attack Machine: The Ultimate Posterior Chain Training Machine

Revolutionary strength training, safer workouts

In the world of iron and sweat, where the scent of determination hangs heavily in the air, there exists a contraption that is a testament to human ingenuity and the relentless pursuit of physical excellence. A contraption that, while not the star of the show, plays a pivotal role in the grand opera of strength conditioning. It's the Sorinex Back Attack, and it's been quietly revolutionizing the way we train our bodies for the better part of two decades.

This is not just a machine. It's a piece of history, a brainchild of Richard and Bert Sorin, and Olympic Medalist Lance Deal, who sought a safer way to fortify the critical muscles in our posterior chain – the glutes and hamstrings. These are the muscles that power our leaps, our sprints, and our lifts, the muscles that keep us upright and moving forward. And yet, they're often underappreciated and neglected, leading to imbalances and injuries.

The Sorinex Back Attack pays homage to an old school exercise – the Good Morning – but adds its own unique spin. It allows the user to load up on weights, providing an opportunity for progressive overload, crucial for muscle and strength development. But it doesn't stop there. This beast of a machine also offers band attachment options, allowing for added resistance and an extra layer of complexity to your training.

It's clear that this machine has earned its stripes. The folks at Liberty swear by it, touting it as their go-to for posterior chain development, even over popular exercises like the Glute-Ham Raise and the Reverse Hyper. Their impressive stats speak for themselves, but what really caught my attention was their commitment to the Back Attack. They have six of these machines, and they wish they had more. That's a ringing endorsement if I've ever heard one.

The craftsmanship of the Back Attack is also commendable. With a depth of 60 inches, a width of 80 inches, and a height of 66 inches, this hulking machine does command its space, but it's worth every square inch. The upholstery, a double-stitched premium Naugahyde, exudes quality and durability, matching the robustness of the plate-loaded design. The multiple height adjustments and band attachment points make it versatile and adaptable, catering to all body types and training levels.

The Sorinex Back Attack may come with a hefty price tag, but it's clear that it's an investment in quality, safety, and most importantly, results. It's a testament to the fact that sometimes, to move forward, we must focus on what's behind us.


  1. Targeted Training: The machine is specifically designed to strengthen the posterior chain – the glutes and hamstrings. These muscles are often neglected in traditional workouts but are crucial for overall strength and balance.
  2. Safety: Unlike traditional Good Morning exercises that can strain the arms and shoulders, this machine allows for targeted and safe workouts, minimizing the risk of injury.
  3. Versatility: With plate-loaded design and band attachment options, you can customize your workout according to your strength level and training goals.
  4. Quality and Durability: Made from high-quality materials and double-stitched premium Naugahyde upholstery, the machine is built to last.
  5. Adjustability: The machine offers height adjustments, making it suitable for individuals of different heights.


  1. Price: The machine comes with a high price tag. It might be seen as an investment for commercial gyms, but for an individual or a home gym, it might be cost-prohibitive.
  2. Space Requirements: With dimensions of 60″ depth, 80″ width, and 66″ height, the machine requires a significant amount of space. This might be a disadvantage for smaller gyms or home setups.
  3. Complexity: For beginners, the machine might seem complex and intimidating. It requires proper understanding and technique to use effectively.
  4. Limited Use: While the machine is excellent for posterior chain workouts, it has a specific focus. This means it's not a comprehensive solution for full-body workouts and would need to be supplemented with other equipment.
  5. Weight Plates Not Included: The machine is plate-loaded, meaning you need to have or purchase weight plates separately. This could be an additional expense and requirement to consider.

Remember, the right fitness equipment for you depends on your individual fitness goals, budget, space availability, and level of experience. The Sorinex Back Attack Machine is a fantastic tool for those focused on strengthening the posterior chain, but it's important to consider all its aspects before investing in it.
