The 2-in-1 adjustable design allows you to effectively perform multiple exercises and develop the strength of the quads, glutes, hamstrings, and calves muscles. This lower-body exercise machine is a premium construction of 4" x 2" heavy-duty steel tubes that can safely support up to 1500lbs. It features an oversized diamond-plated footrest for multiple foot positions, longer and wider 2.5” thick support padding for shoulders and lower back areas for a comfortable workout experience, and undercarriage dual-weight sleeves that perfectly fit Olympic-style plates.
The sizeable anti-slip foot base provides enough space for multiple foot positions to engage different muscles group by placing feet at different positions and angles during hack squats. High-density flip-and-lock back padding reduces stress on the back and shoulders during workout. Easily accessible 4 lock positions and dual side rails handles are also essential parts of its innovative design for safe and secure heavy-weight lifting. Fold handrails inside to start your workout and fold them out to lock the carriage bar in your comfortable position.
This Ultimate Leg Press machine is angled at 45 degrees, and you can quickly switch from leg press to hack squat in seconds; flip the back pad and drop the leg press footplate. The versatility of this machine aims to serve both beginners and professional athletes at commercial and home gyms. It is coated with black powder that effectively resists rust and scratches for long-time reliability.
