Feature

Detailed Explanation

Machine Type

Plate-loaded dual-function machine

The Atlantis leg press hack squat machine uses weight plates, which allow very heavy loading and gradual overload. 

Primary Purpose

Hack squat + leg press combination

The Atlantis hack squat leg press is designed to switch between a hack squat (upright pressing) and a leg press (more horizontal pushing) position.

Movement Path

30° angled sled track

The sled moves along a fixed 30-degree incline, balancing quad focus and joint-friendly biomechanics.

Frame Construction

Heavy-duty steel frame

Built for commercial gyms with reinforced steel for stability under very heavy loads.

Backrest System

Adjustable back pad

Changes angle/position to switch between hack squat posture and leg press setup.

Foot Platform

Large adjustable platform

Hack squat machine Atlantis allows different foot placements (high/low/wide/narrow) to work on quads, glutes, or hamstrings differently.

Shoulder Pads

Ergonomic angled pads

The hack squat Atlantis machine is designed to distribute pressure across traps and shoulders, reducing discomfort during heavy squats.

Safety System

Built-in safety catches + auto disengage

Permits the start/end of the rep to be handled without the aid of a spotter - easy lock and unlock of the sled. 

User Height Adjustment

Multiple racking positions

Suitable for most body sizes to allow proper positioning of knees and hips throughout the movement. 

Starting Resistance

Built-in sled weight (61 kg / 135 lb)

Even without plates loaded, the sled itself will offer some resistance due to its mass. 

Maximum Load Capacity

653 kg / 1440 lb

The sled itself can support very heavy loads - ideal for strength athletes. 

Sled Mechanism

Nylon rollers on steel rails

A low-friction sled allows for extremely smooth movement throughout the entire range of motion. 

Band Resistance Option

Upper & lower band pegs

Bands can be added for variable resistance - this makes the movement harder at either the top or bottom portion of the movement. 

Foot Angle Adjustability

Adjustable incline platform angle

The movement shifts knee and hip positioning to work quads more or glutes and hamstrings. 

Biomechanics Focus

Knee-dominant movement pattern

Muscles worked are predominantly quads - quads with some glutes and hamstrings if the foot position is adjusted. 

Design Collaboration

Designed with biomechanics input

Input provided by strength coach Kassem Hanson for increased range of motion. 

Machine Weight

337 kg / 742 lb

High mass sled base provides stability under the heaviest of loads. 

Dimensions

104” × 67” × 55”

Extra-large footprint makes it perfect for a commercial gym environment.
