Grip the handle and guide the weighted ball through smooth, controlled circles.

⚙️ The rotating weight creates continuous, shifting resistance

💪 This engages your grip, forearms, shoulders and stabilizer muscles

🎯 Unlike static weights, the resistance changes throughout every rotation

🔄 The smooth circular movement helps build strength, control and endurance

Everyone progresses differently, but consistent use is what matters most.

☝️ First few sessions: You may immediately feel your grip, forearms and shoulders working in a new way

📅 After a few weeks: Many users notice improved control, endurance and movement confidence

💪 With regular use: Strength and stability can continue improving over time

The built-in counter makes it easy to track each session and stay consistent.

    FAQs

    SpinFlex™ is designed for one specific purpose: building controlled strength through continuous rotational resistance.

    • The weighted ball creates resistance that shifts throughout every rotation
    • This challenges your wrists, forearms, shoulders and smaller stabilizer muscles
    • Unlike a dumbbell or resistance band, the load keeps changing as you move
    • Many users feel the muscles working differently from their very first session

    SpinFlex™ is best suited to the strengthening stage, after a doctor or physiotherapist has cleared you to begin resistance exercise.

    • It is not intended for immediate post-surgery recovery
    • It does not replace early-stage rehabilitation exercises or physiotherapy
    • Begin with slow movements and short sessions
    • Ask your healthcare professional before use when recovering from an injury

    You may notice mild muscle fatigue in your forearms or shoulders during the first few sessions, especially when these muscles are not used to rotational training.

    • Start slowly and allow your body time to adapt
    • The goal is smooth control—not speed or maximum effort
    • Regular, low-impact sessions are more useful than occasional intense workouts
    • Stop using it if you experience sharp pain or worsening discomfort

    The built-in counter records the number of rotations completed during your session.

    It gives you a simple way to:

    • Track your repetitions
    • Compare sessions over time
    • Set manageable daily targets
    • Stay consistent without guessing

    Start with 2–3 minutes per arm and gradually increase as the movement becomes comfortable.

    • Beginners can aim for approximately 5–10 minutes total
    • Take breaks whenever your grip or shoulder begins to tire
    • Focus on controlled circles rather than completing as many rotations as possible
    • Use it while sitting, standing or relaxing at home

    The circular motion is designed to be smooth and low impact, but every surgery and recovery plan is different.

    SpinFlex™ is a fitness and strengthening tool, not a medical device or substitute for professional rehabilitation. Obtain approval from your surgeon or physiotherapist before using it after surgery.

    Not at all.

    SpinFlex™ can also be used by people who want to:

    • Strengthen their grip and forearms
    • Improve shoulder control and stability
    • Add variety to their home workouts
    • Maintain upper-body strength as they get older
    • Support active hobbies, sports or everyday movement
