Force USA Fractional Weight Plates for All-in-One Trainer (2 × 1.5 kg)

Subtle weight increases that make all the difference—Force USA’s fractional weight plates allow for precise progressions in 1.5-kg increments per side. Ideal for anyone looking to break through plateaus or systematically incorporate even the smallest gains into their training.

The Problem with Large Changes in Weight

If you increase the weight on your all-in-one trainer in 5-kg increments during heavy exercises like shoulder presses or rowing, you risk compromising your form and hitting a plateau sooner. Fractional weight plates solve this problem: At 1.5 kg per side, the stimulus remains small enough to maintain proper form—but large enough to trigger genuine neuromuscular adaptation.

Compatibility

Specially designed for Force USA's all-in-one trainers (G3®, G6™, G9, G12™, G15™, G20™, and other models). The plates fit precisely onto the weight stack guide of Force USA machines and complement the existing system without requiring any modifications.

Benefits at a Glance

• A fine weight progression for increases below the standard set interval
• No modification needed—just place it on top of the stack of weights
• Sturdy metal construction for a long service life

Who is this for?

Particularly valuable for advanced athletes who train close to their maximum strength, as well as for rehabilitation patients who are gradually rebuilding their strength. It is also suitable for older athletes who want to increase their strength gradually, or for sports in which technique takes precedence over raw strength.
