R7 Jammer Arms

Fast Adjustment. Maximum Versatility

• The Jammer Arms mount to any of the 33 adjustment holes on R7 uprights, giving you the flexibility to perform a wide range of guided strength exercises.
• Position them low for deadlifts, bent-over rows, and floor presses, or quickly raise them for squats, seated rows, military presses, and chest presses. Simply release the safety pins and slide the arms into position using the integrated handles.
  
• Military press and bench press at different angles are also possible.
• Get the benefits of machine training at home—simple, space-smart and cost effective.
• Unlike many comparable systems, the Jammer Arms can be adjusted without removing them from the rack, making height changes faster and easier.
  
• Hard plastic liners prevent metal-to-metal contact, protecting both the Jammer Arms and your rack from wear.

Varied Training for Beginners and Advanced Lifters

• The Jammer Arms can be moved independently of each other, making them ideal for unilateral exercises - i.e. those that train both sides of the body alternately.
• Especially useful for addressing muscular imbalances or protecting injured areas.
• The guided movement path provides greater control throughout every repetition, helping beginners build confidence while giving experienced lifters a consistent pressing path for explosive strength work.
  
• Great for improving performance in sports that involve striking or throwing.
• Load the arms with any standard 50 mm weight plates to match your strength level and training goals.
  

High Functionality in a Small Space

• With the Jammer Arms, you can easily run a full-body training session—they support both pressing and pulling movements.
• This versatile tool stays tight to the rack and takes up zero floor space.
• The handles can be removed in seconds, allowing clear access in and out of the rack.
• They also offer different grip options, from supinated and pronated, through neutral to angled.
• You can also adjust your grip width based on your preference.
• There are ten mounting positions for handles along the Jammer Arms.
• This lets you change the lever length—and with it, the training stimulus—based on the movement.
• Heavy-duty eyelets at the end of each arm allow you to attach additional cable handles or secure the arms in an elevated position when not in use, keeping the uprights clear for other rack attachments.
