Among the top-tier equipment available in gyms today, the Star Trac Hack Squat machine stands out for its ergonomic design, durability, and biomechanical efficiency.

What Is the Star Trac Hack Squat?

The Star Trac Hack Squat machine is a plate-loaded lower-body machine designed to target the quadriceps, glutes, and hamstrings. Unlike traditional barbell hack squats, which place a bar behind the legs and can strain the lower back, the Star Trac version provides a supported backrest and angled foot platform to promote a safer, more natural squat path.

Its design ensures that your spine remains in a stable, supported position throughout the lift, allowing you to focus on leg drive and muscle engagement without compensatory strain.

Understanding the Starting Weight

One of the most common questions lifters have is about the starting weight on a Star Trac Hack Squat. This refers to the resistance the machine offers before any plates are added. Because the machine uses a sled mechanism that glides on rails, there’s an inherent weight to the carriage—even when unloaded.

• Typical Starting Weight: The sled on a Star Trac Hack Squat generally weighs around 75 to 85 lbs. However, this may vary slightly by model and year of manufacture.

• Why It Matters: Knowing the starting weight helps lifters—especially beginners—gauge how much load they're truly lifting. For instance, adding two 45-lb plates (one per side) means you're actually pressing around 165 to 175 lbs, not just 90 lbs.

Proper Setup and Form Tips

To get the most out of the Star Trac Hack Squat while protecting your knees and back, follow these setup tips:

1. Foot Placement
   Position your feet shoulder-width apart on the platform. A higher placement emphasizes glutes and hamstrings, while a lower stance targets the quads.

2. Back and Shoulder Alignment
   Keep your back flat against the pad, with shoulders snug under the support pads. Avoid lifting your heels or allowing your knees to track inward.

3. Controlled Movement
   Lower the sled slowly until your thighs reach parallel or slightly below, then drive up through your heels. Don’t lock out your knees at the top.

4. Warm-Up With Just the Sled
   Especially if you’re new to the machine, try a few reps using only the starting sled weight. This helps you assess your mobility and form before loading plates.
