Unlock Dynamic Training Potential – Athletic Performance Meets Rack Attachment
Standard power rack training focuses on linear movements—squats, presses, and pulls in fixed planes. The Spartaks Strength Jammer Arms expand your training into rotational and explosive movement patterns that traditional rack exercises cannot provide. These lever-style arms pivot from the rack uprights, creating arc-based resistance curves that challenge athletes in ways straight-line movements cannot replicate.
From explosive landmine presses that build upper body power to rotational core work that develops athletic rotational strength, these jammer arms transform any compatible power rack into a comprehensive athletic training station. The 42-inch arm length provides ample range of motion for tall and short users alike, while the 35mm handle diameter offers a comfortable, secure grip for heavy work. Whether you're a competitive athlete building explosive power, a strength coach programming athletic development, or a serious lifter seeking training variety, these jammer arms deliver the versatility that modern training demands.

Exercise Capabilities – Dynamic Movement Training
The jammer arms unlock exercise variations that transform standard rack training into comprehensive athletic development.
Landmine Press Variations
The pivoting arm action mimics landmine training, allowing for standing chest presses, shoulder presses, and one-arm pressing variations. The arc-based resistance curve challenges stabilizer muscles while the leverage provides a unique strength curve that differs from traditional pressing. Excellent for building upper body power and addressing strength imbalances between sides.
Explosive Power Development
Jammer arms excel at explosive pressing movements that build athletic power. The lever action allows for acceleration through the movement, teaching athletes to generate force rapidly. From explosive chest throws to dynamic shoulder work, these movements develop the power that transfers directly to sports performance.
Rotational Core Training
The pivot point enables rotational movements that train the core through functional patterns. Landmine rotations, Russian twists, and rotational presses develop the oblique strength and rotational power essential for sports like golf, baseball, tennis, and hockey. This core training goes beyond static planks into dynamic, athletic movement.
Rows & Pulling Movements
Position the arms for horizontal and diagonal rowing variations that target the back from different angles. The pivoting action creates a unique resistance curve for rowing movements, engaging stabilizer muscles and challenging the back through a full range of motion. Excellent for building back thickness and strength.

Key Training Benefits
The Spartaks Strength Jammer Arms deliver benefits that make them essential for comprehensive athletic and strength training.
Expand Your Rack's Capability
Transform your power rack from a station for linear exercises into a comprehensive training center. The jammer arms add pressing, pulling, and rotational movements that your rack cannot perform on its own. This versatility maximizes your equipment investment and training variety without requiring additional machines or floor space.
Athletic Power Development
The lever-style action enables explosive training that develops the power athletes need. Unlike machines that control the speed, jammer arms allow for acceleration and explosive intent—critical for sports performance. Build the upper body power that transfers to throwing, striking, and explosive athletic movements.
Rotational Strength & Core Development
Most gym equipment trains in straight lines, but sports happen in rotational patterns. Jammer arms enable the rotational movements that develop functional core strength and athletic power. Train the obliques, core, and rotational patterns that translate directly to sports performance.
Heavy-Duty 9-Gauge Construction
Built from 3" × 3" 9-gauge steel, these jammer arms handle serious training loads without flexing or instability.

Frequently Asked Questions About the Jammer Arms
Will these fit my power rack?
The Spartaks Strength Jammer Arms are designed for power racks and rigs with 3" × 3" upright tubing. This is the industry standard for professional-grade racks. If your rack has 3" × 3" uprights, these jammer arms will fit. Measure your uprights before ordering—if they're 3" × 3", you're compatible. Racks with 2" × 2" or 2" × 3" uprights will not work without adapter solutions.
How do jammer arms differ from a landmine attachment?
Both provide arc-based pressing movements, but with key differences. A landmine uses a barbell anchored at one end, creating an arc with variable resistance based on the bar angle. Jammer arms are rigid lever arms with a fixed pivot point, providing more consistent leverage and often greater stability for explosive movements. Jammer arms also allow for plate loading directly on the arms, and the fixed handles provide consistent grip positioning. Many athletes use both for training variety.
How much weight can these jammer arms hold?
The 9-gauge steel construction is engineered for substantial loading capacity suitable for explosive athletic training. The robust build handles the dynamic forces of explosive pressing without flexing. For specific weight capacity ratings, contact our team with your training requirements. These arms are built for the demands of serious strength and athletic training facilities.
What exercises can I do with jammer arms?
Jammer arms support numerous exercises across pressing, pulling, and rotational categories. Popular movements include: standing chest presses, shoulder presses, one-arm presses, explosive throws, landmine rows, Meadows rows, rotational presses, Russian twists, and rotational core work. The pivoting action also allows for hybrid movements that combine pressing with rotation. The versatility makes them valuable for athletes, bodybuilders, and general strength training alike.
Are these suitable for home gym use?
Absolutely. If you have a power rack with 3" × 3" uprights, jammer arms add significant training variety to your home gym without requiring additional floor space. They're particularly valuable for home gyms where space efficiency matters—the arms mount to your existing rack, so you gain dozens of new exercises without sacrificing square footage. The 120LB weight means they're substantial enough for serious training but manageable for setup.
Do I need two jammer arms or just one?
This product is sold as a pair (two jammer arms). Having both arms enables bilateral exercises like standing chest presses and two-arm explosive movements, while also allowing you to use a single arm for unilateral work. Most training programs benefit from having both options available. If you're outfitting a facility, having both arms provides complete training flexibility.
