LITE® INERTIA Full Edition Flywheel Training System
- Description
Train with precision, control and power using the LITE® INERTIA Full Edition. This Italian-engineered flywheel platform delivers eccentric overload and kinetic feedback for serious athletes and trainers.
How It Works
The INERTIA system generates resistance through inertia and kinetic energy stored in a spinning flywheel. As you pull the rope concentrically, the flywheel accelerates. When you release it, the flywheel reverses and your muscles decelerate eccentrically. The faster you move, the greater the resistance. This dual-action cycle builds strength, power and control in both phases.
Key Features
• Speed-Dependent Variable Resistance: The faster you pull, the greater the resistance. INERTIA returns the same energy on the eccentric phase, allowing eccentric overload by shortening deceleration time.
• Integrated Quick-Change Resistance System: Adjust intensity instantly — no need to add or remove flywheels.
• Rope Regulation System: Set rope length quickly for a customized range of motion.
• Optimized Platform Design: Perform exercises both above and outside the base for maximum versatility.
• Cylindrical Shaft: Enables greater overload during eccentric movements for advanced conditioning.
• Optional Wall Guide: Supports open-chain, horizontal exercises for sport-specific training.
• Patented LITE® Resistance System: Change resistance with a simple slide of the colored sleeve — fast, efficient and intuitive.
• Portable Build: Integrated wheels for effortless transport and repositioning.
Included Accessories (Full Edition)
• Squat belt (one size)
• Dual handles (28 mm grip)
• Handlebar (28 mm grip)
• Anklet strap
• Inclined push board

"After 6 months with the XMARK Functional Trainer, I can confidently say it's the best investment I've made for my home gym. The cable system is incredibly smooth, and the weight stack provides consistent resistance throughout the full range of motion. Build quality is commercial-grade - feels like equipment you'd find in a premium gym." — Marcus T., Chicago, IL
"I was hesitant about the space it would take up, but the XMARK's compact design fits perfectly in my garage gym. The variety of exercises I can do is endless - from lat pulldowns to functional movements. Assembly was straightforward with clear instructions." — Lisa M., Portland, OR
I’ve had mine for almost a year and couldn’t be happier. It was nearly double the price when I bought it, and I’d still do it again. The tub gets cold fast, feels great, and I love that I can deflate and store it in winter. Support was quick and friendly when I called. Friends and family love using it too. Highly recommend!
