Overview
The Exxentric SingleExx Combo is a professional-grade flywheel training system designed for focused, unilateral lower-body development. This "all-in-one" station combines the inertia-driven resistance of Exxentric’s flywheel technology with a specialized, space-efficient frame. It is engineered to perform elite-level leg extensions and seated leg curls on a single platform, offering a superior alternative to traditional weight-stack machines by providing variable resistance and significant eccentric overload.

Key Features and Specifications
Resistance System: Flywheel-based kinetic energy (Inertia-driven).
Dual Functionality: Easily transitions between seated leg extensions and seated leg curls.
Frame Construction: High-strength, powder-coated steel with a compact footprint.
Flywheel Compatibility: Supports up to two flywheels simultaneously (sizes ranging from XS to XL).
Inertia Range: 0.005 kgm² to 0.140 kgm².
Data Feedback: Built-in kMeter II for real-time Bluetooth tracking of power, force, and energy.
Adjustability: Features adjustable seat depth, backrest angle, and shin-pad positioning to accommodate various athlete sizes.
Color: Space Gray.
Performance Benefits
Variable Resistance: The flywheel provides a load that perfectly matches the user's force output. The more intent you put into the concentric (push/pull) phase, the more resistance the machine provides during the eccentric (lowering) phase.
Eccentric Overload: Specifically designed to allow for supra-maximal eccentric loading, which is a primary driver for muscle hypertrophy, tendon strengthening, and injury prevention in the quadriceps and hamstrings.
Unilateral Precision: By focusing on one leg at a time (Single-Exx), athletes can effectively identify and correct bilateral strength deficits that are often hidden by standard bilateral machines.
Scientifically Optimized Angles: The seated position for leg curls targets the hamstrings at longer muscle lengths, which has been proven more effective for muscle growth than lying variations.
Compact Footprint: Replaces two large commercial selectorized machines with a single, mobile unit, making it ideal for high-performance home gyms and boutique training studios.
Maintenance and Care
Drive Belt Care: Regularly inspect the drive belt for fraying or localized wear. If the belt shows signs of damage, it should be trimmed or replaced to ensure safety during high-power output.
Hardware Tension: Periodically check and tighten all assembly bolts and adjustment knobs to ensure the frame remains rigid and vibration-free.
Surface Cleaning: Wipe down the vinyl upholstery and powder-coated frame with a mild soap and water solution after use. Avoid using alcohol-based cleaners on the vinyl.
Flywheel Security: Always ensure the flywheel knob is tightened securely before starting a set to prevent the discs from wobbling or loosening during rotation.
Frequently Asked Questions
Q: How long does it take to switch from leg extensions to leg curls? A: The transition is quick and tool-less, typically taking less than 30 seconds by adjusting the swing arm position and the seat settings.
Q: Do I need a power outlet to use the kMeter? A: No. The kMeter II sensor is battery-operated and syncs wirelessly via Bluetooth to your smartphone or tablet using the free Exxentric app.
Q: Can I use this for bilateral (two-leg) training? A: While the machine is optimized for unilateral (single-leg) movement to maximize eccentric overload, it can accommodate bilateral training depending on the user's size and force requirements.
Q: Is the resistance heavy enough for elite athletes? A: Yes. Because the resistance is inertia-based, there is no "max" weight. By using heavier flywheels and increasing movement velocity, even world-class athletes can generate massive force levels.
