Leg Extension/Curl Combo Comparison At a Glance

An In-Depth Analysis of our Premium Leg Extension/Curl Combo Machines
1. Resistance Mechanism
LeverEDGE #6011: Employs a plate-loaded system with two 9-inch chrome-plated weight pegs, each capable of holding up to six Olympic plates. This setup is better suited for advanced athletes who require heavier loads and prefer the feel of free weights.
SelectEDGE #1125: Utilizes a 250-pound selectorized weight stack, allowing for quick and easy weight adjustments via a selector pin. This system is user-friendly and ideal for environments where multiple users require rapid changes in resistance.
2. Exercise Functionality
LeverEDGE #6011: Provides seated unilateral leg extensions and standing leg curls. The unilateral design ensures balanced muscle development by allowing each leg to work independently, preventing the dominant leg from compensating for the weaker one.
SelectEDGE #1125: Offers seated leg extensions and prone leg curls, with smooth transitions between exercises facilitated by pop-pin adjustments.

3. Adjustability and User Accommodation
LeverEDGE #6011: Offers more granular adjustments with leg rollers adjustable in 1-inch increments (16.5″ to 21.5″) and a seat back that adjusts in six 1-inch increments. These features accommodate users of varying sizes and ensure proper alignment during exercises.
SelectEDGE #1125: Features an adjustable seat back for leg length, multiple starting positions, and an adjustable thigh pad. The weight stack is easily accessible from the exercise position, enhancing user convenience.
4. Space and Portability
LeverEDGE #6011: Larger footprint with dimensions of 61.5″ x 76″ x 48″ and a shipping weight of 380 pounds. It ships fully assembled, but its lighter weight may ease relocation within the facility.
SelectEDGE #1125: Dimensions are 52.25″ x 49″ x 63.25″ with a shipping weight of 950 pounds. This machine also ships fully assembled, which may require consideration for entryways and installation logistics.
5. Durability and Maintenance
LeverEDGE #6011: Features a fully welded frame, pillow block bearings with grease fittings, and marine-grade, stain-resistant upholstery. These elements contribute to the machine’s durability and longevity.
SelectEDGE #1125: Constructed with high-grade steel and designed for low maintenance. The machine’s components are built to withstand frequent use, making it suitable for high-traffic environments.
Final Thoughts on the Differences Between the LeverEDGE and SelectEDGE Leg Extension/Curl Combo Machines
If you have high school athletes with varying experience levels, it is likely your need is for equipment that is both user-friendly and durable. In this case, the SelectEDGE Leg Extension/Curl Combo (1125) appears to be the more suitable option. Its selectorized weight stack allows for quick adjustments, accommodating multiple users efficiently. The machine’s design prioritizes ease of use, making it ideal for a high school setting where safety and accessibility are paramount.
However, if your program places a significant emphasis on unilateral training to correct muscle imbalances and you have athletes requiring higher resistance levels, the LeverEDGE Unilateral Leg Extension/Curl Combo (6011) would be advantageous. Its plate-loaded system and unilateral functionality cater to advanced training needs.
