Yes, but the dummy may become too stiff. Mixing clothes with polyfill creates a more realistic feel for training.

Use polyfill in the arms and legs to keep them flexible and easier to grip during drills and submissions.

The head should always be filled with soft polyfill or foam to avoid stiffness and maintain shape.

For adults, 20–35 kg is commonly recommended depending on dummy size and training style. For kids, lighter weights are recommended for easier movement.

Use heavier materials in the torso and softer filling in the joints, arms, and head for better balance and movement.
