Spartaks Strength 3"X3" Jammer Arms

Explosive power, mounted right on your rack. The Spartaks 3"×3" Jammer Arms add lever-style pressing, pulling, and rotational movement to your rack — the kind of explosive, athletic training you can't get from a fixed cable pulley or straight bar path. Each arm pivots independently, letting you train single-arm power and rotational patterns side by side.

Available in 36" or 42" arm lengths, choose the length that matches your space and training style. Built from 3"×3" 9-gauge steel with 35mm Olympic-diameter handles, they mount directly to your rack uprights and hold up to heavy, explosive loading.

• Explosive Pressing — Jammer presses and single-arm presses for explosive upper-body power development.
• Athletic & Rotational Training — Rotational movements and sport-specific patterns that build functional, transferable strength.
• Strength Building — Heavy presses and pulls using the lever action for resistance curves you don't get from a straight bar.
