The Dip Bars, which attach to the front of the unit, are ideal for building strength in your chest, shoulders, and triceps, and are also finished with a high-grade black powder coating. By incorporating the Force USA G20 Upgrade Kit into your setup, you can significantly expand your exercise options, target multiple muscle groups more effectively, and achieve greater strength gains.

● Jammer Arms (1 pair)
● Dip Bars (1 pair)
● 1 x Leg extension/curl Attachment
● Compatible with Force USA G1 All-In-One Trainer


The jammer arms require Westside hole spacing (25mm) for proper attachment. They are fully compatible with G20 Pro model. However, on the original G20 model, the jammer arms can only attach to the uprights at a maximum height of 130cm. The uprights on the original G20 lack Westside hole spacing throughout their entire height, which is necessary for attaching the jammer arms. For proper attachment of the jammer arms, Westside hole spacing must be available on the uprights.
