The DDR003 Leg Press / Hack Squat from the DDR Series by Dynasty Fitness is a powerful 2-in-1 machine that combines two of the most effective compound leg exercises, the leg press and the hack squat, into one compact, commercial-grade unit. Designed for both high-performance gyms and space-conscious training environments, this dual-function lower body machine allows you to build muscle, enhance athletic performance, and protect your joints all in one station.
Whether you're an athlete working on power output or a fitness enthusiast targeting quad, hamstring, and glute development, the DDR003 offers the versatility, safety, and durability needed to train smarter and harder.
Two Classic Movements. One Intelligent Design.
The DDR003 is engineered to seamlessly shift between leg press and hack squat configurations with minimal effort. By adjusting the back pad angle, footplate, and carriage, users can go from Leg Press to Hack Squat with no tools and no delays.
- Leg Press Mode emphasizes the quads, glutes, and calves with a controlled, horizontal plane of movement ideal for beginners, advanced hypertrophy, and joint-friendly strength training.
- Hack Squat Mode simulates a deep squat with back support, encouraging maximum depth and glute engagement while reducing stress on the lower back and knees.
This flexibility allows for training variety and improved muscle targeting without occupying additional space or requiring two separate machines.
Linear Bearings for Smooth Motion
The DDR003 features a durable linear bearing system that allows the carriage to glide smoothly along the guide rods. This ensures friction-free movement during heavy lifts and provides a more natural feel throughout the range of motion.
Compared to traditional plate-loaded sleds, the linear bearings offer enhanced control, reduced wear, and a quieter training experience making it perfect for high-traffic training spaces or private studios.
Built for Safety and Comfort
The machine is designed with the user’s safety and performance in mind. The adjustable footplate offers five angles to accommodate a range of training preferences, ankle mobility levels, and muscular emphasis such as glute-dominant or quad-dominant foot placement.
Sliding handles on each side allow for quick adjustment of the carriage and support easy entry and exit, while thick shoulder and back pads offer complete support under load.
Additional safety highlights:
- Maximum Training Load: 661 lbs
