Major Fitness Cobra AH1 Leg Press & Hack Squat Machine (2-in-1 Plate-Loaded Lower Body System, 600 Lb. Heavy-Duty Capacity)
Blast through leg day plateaus and isolate your lower body safely with the Major Fitness Cobra AH1 Leg Press & Hack Squat Machine. Engineered as a premium, light-commercial 2-in-1 strength hub for home garages and private training spaces, this specialized 45-degree angled track system combines multiple standalone lower-body platforms into a singular, highly efficient floor footprint.
By switching rapidly between a classic leg press, a linear shoulder-loaded hack squat, a reverse hack squat, and an elevated calf raise block, the Cobra AH1 isolates your quads, hamstrings, glutes, and calves without transferring compression stress or pain to your lower back.
2-in-1 Dual Lower Body Ergonomics
-
Under-a-Minute Quick-Switch Cushion System: Eliminate tedious, multi-step equipment conversions. The Cobra AH1 uses an intuitive snap-and-lock removable pad configuration. To shift from leg pressing to hack squatting, simply lift out the back support cushion, slot it flat down onto the lower platform to serve as your foot plate, flip back the upper shoulder carriage, and begin lifting in under 60 seconds.
-
45-Degree Fluid Nylon Roller Bearings: Driven by an industrial guide rail assembly paired with precision high-density nylon roller bearings. This commercial-style tracking architecture provides a completely silent, ultra-smooth glide along the steel tracks, drastically dropping mechanical friction and reducing routine lubrication maintenance.
-
Independently Adjustable Dual Footplates: Designed to support customized stances, anatomical variations, and targeted muscle tracking. Features a 5-position upper footplate (19.29" x 18.11") matched with a wide 4-position lower footplate (19.29" x 23.62") to lock in precise knee and ankle alignment across every rep.
Heavy-Duty Capacity & High-Safety Engineering
-
Rigid 600 Lb. Structural Load Capacity: Forged from high-grade, heavy-wall structural steel tubing designed to comfortably sustain up to a 600 lb. weight capacity. The rock-solid, low-slung steel frame distributes mass evenly across your floor, staying entirely stable and wobble-free during maximum-load sets.
-
3-Level Lockout Safety Handrails: Outfitted with dual-sided mechanical stopper rails offering 3 easily accessible lockout positions. Positioned directly at your fingertips in both leg press and hack squat configurations, you can easily rack or unrack the weight carriage at various heights to ensure safe solo training.
-
Multifunctional Linear Band Pegs: Built with specialized lower frame pegs to anchor progressive resistance bands. Hooking bands to the sled adds an aggressive, ascending variable resistance curve during the concentric phase while serving as an additional protection catch at the track bottom.
Premium Contact Points & Plate Storage
-
Anti-Slip Sweat-Resistant PU Leather Padding: Both the oversized shoulder-cradle pads and back supports are lined with premium, high-density anti-slip PU leather. These dense pads provide exceptional lumbar support, won't deform under heavy weight blocks, and wipe down cleanly.
-
Integrated Olympic Post Storage Array: Outfitted with 13.78-inch dual weight carriage horns paired with 7.87-inch rear storage pegs sized perfectly for 2-inch standard Olympic plates. Storing your change plates directly on the back base utilizes their mass to ground the frame, maximizing structural footprint balance.

Target Lower Body Training Variations
-
45-Degree Leg Press: Rest flat against the lumbar padding and press against the upper footplate. Shifting your feet to the top of the plate fires up the glutes and hamstrings, while dropping them low isolates the lower quadriceps.
-
Linear Hack Squat: Secure your shoulders under the PU pads, step onto the lower plate, and drive upward. This variation emphasizes quad development and core stabilization with zero spinal loading.
-
Reverse Hack Squat & Standing Calf Raises: Face the machine pad directly to isolate the glute-hamstring tie-in via reverse squatting, or use the bottom edge of the lower footplate to execute high-stretch calf press extensions safely.
