What Is the Sandbag Zercher Squat?

The Zercher squat sandbag exercise involves holding a sandbag in the crook of your elbows while squatting. This unique positioning forces greater engagement of the upper back, core, and legs compared to traditional front or back squats.

Origins of the Zercher Squat

The Zercher squat was originally developed by Ed Zercher, a strongman from the 1930s. Traditionally, it was performed with a barbell, but using a sandbag adds an element of instability, requiring greater control and functional strength.

Why Use a Sandbag Instead of a Barbell?

• Increased Core Activation – The shifting weight of the sandbag forces the core to work harder.
• Functional Strength Gains – Mimics real-world lifting, making it practical for athletes, firefighters, military personnel, and strongman competitors.
• Joint-Friendly – Less stress on the wrists, shoulders, and lower back compared to traditional barbell squats.
