The GOAT Attachment is designed to be one of the most versatile rack attachments, replacing the need for multiple standalone machines. Bronze bearings allow smooth rotation, and the bracket’s five pin holes let you pin the tube in at 11 different angles. The GOAT Attachment includes the bracket, a 24" tube with 1" holes, and two hitch pins. Attachments are sold separately. Both the 1" and 5/8" versions have identical frames, with the 5/8" model featuring a different threaded pin.

The Alpha Arms offer 180° range of movement when unlocked in both the Z and X planes, allowing for a more natural feel during pressing, rowing, and other exercises. They can lock into a straight position like traditional lever arms or at angled positions for varied movement options. They are compatible with both 1″ and 5/8″ holes on 3×3" tubing and the bracket can be disassembled to add to welded frame racks.

The Alpha Bench is constructed out of 3×3 tubing and has attachment holes on the back for 1″ attachments. The back pad is 40″x 12″ with a 1.25″ pad gap between the seat pad which is 12.5″x 12″. The bench in the renderings and pictures are showing a Premium black pad with a black wear cover, Laser Cut SD Logo, Red Frame, and Silver Accent Color.
