    Super easy to use and the resistance feels just right. The build is solid, nothing flimsy at all, and the movement is really smooth. I love how many different workouts I can do with it - worth every penny!

    I get an amazing pump and sweat quickly with this. My wife also uses it by adjusting the resistance to her level, and she enjoys it as much as I do. Compact, easy to store, and a great investment for any home.

    Excellent 4.8 / 5

    • Exactly what I needed for home workouts.

      I was tired of having multiple bulky pieces of equipment at home, but nothing really worked for my arms and chest the way I wanted. The CoreFlex Twister™ Pro is compact but insanely effective — within 3 weeks I noticed my arms looking more defined and my chest stronger. It’s easy to adjust resistance, so I can push harder every week. Definitely a game-changer for my fitness routine.

      Alex P., 28 – California

    • Strength and definition in weeks!

      I started using the CoreFlex Twister™ Pro every day at home, and in just a few weeks my upper body started transforming. My shoulders look broader, my chest feels tighter, and my abs are finally showing. The adjustable resistance makes it challenging but safe, and it stores away easily after each session. Best investment I’ve made for myself this year.

      Michael L., 41 – Florida

    • Better than going to the gym.

      I didn’t think one tool could target so many muscle groups until I tried this. Chest, arms, shoulders, even my core — it hits everything. I save so much time because I can get a full workout in 15 minutes. The build quality is solid too, nothing flimsy. Honestly feels like I’ve replaced half my gym equipment with this one product.

      David R., 34 – Texas

        FAQs

        How does the CoreFlex Twister™ Pro work?

        The CoreFlex Twister™ Pro uses a hydraulic resistance system that can be adjusted from 22 lbs up to 440 lbs, allowing you to progressively overload your muscles just like in the gym. By twisting the resistance knob and adjusting arm positions, you can target your chest, shoulders, triceps, biceps, back, and core. This unique design mimics natural pushing and pulling movements, helping you build strength, improve muscle endurance, and maximize performance with one compact tool.

        How much resistance can I train with?

        The CoreFlex Twister™ Pro offers step-less adjustable resistance from 10 – 200 kg (22 – 440 lbs). Simply twist the adjustment knob to fine-tune the weight instantly. Whether you’re a beginner building a foundation or an advanced lifter pushing limits, this trainer adapts to your level—making it perfect for progressive overload training.

        Is the CoreFlex Twister™ Pro safe to use? Are there any side effects?

        Yes! The CoreFlex Twister™ Pro is built for safe, everyday training. Its high-carbon steel frame, non-slip ergonomic handles, and sealed hydraulic system are designed to handle intense workouts without risk of sudden snaps or instability.


        Because it’s a mechanical resistance trainer, there are no drugs, no electronics, and no harmful side effects—just pure strength training that works with your body’s natural movement. When used with proper form, it’s safe for both beginners and advanced lifters.

        How do I use the CoreFlex Twister™ Pro?

        • Using the CoreFlex Twister™ Pro is quick and easy. Simply adjust the resistance level by turning the knob, set the arm length to your comfort, and grip the non-slip handles securely. From there, choose your exercise—whether it’s chest presses, arm curls, shoulder pulls, or even ab rollouts.
        • Each session can be as short as 10–20 minutes, 3–4 times per week, depending on your fitness goals. A detailed exercise guide with variations is included to help you maximize results safely and effectively.

        What muscles does it target?

        The Twister is a multi-functional full-body trainer, primarily activating:

        • Chest & Pectorals – build strength and size
        • Shoulders & Upper Back – improve posture and stability
        • Triceps & Biceps – sculpt powerful arms
        • Forearms & Grip – boost endurance and functional strength
        • Core & Abs – when used as an ab roller or stabilizer

        By changing grips or arm positions, you can unlock dozens of exercise variations for a full workout anywhere.

        What is it made of?

        Engineered for durability and safety:

        • High-Carbon Steel Frame + Piston – built to handle 100,000+ compression cycles
        • ABS/TPR Non-Slip Grips – comfortable, sweat-resistant, and ergonomic
        • Sealed Hydraulic Cylinder – delivers smooth, controlled resistance with no jerks
        • Reinforced Rivets & Easy-Store Buckle – ensures stability, safety, and compact storage
        • This rugged build guarantees long-lasting performance for home, gym, or travel workouts.
