Armor model is static and not animated

Ive made an armor model in Blockbench (just a bunch of random stripes), exported it as a .java object and binded a texture to it. The problem is, it is not rendered as it should, it just floats with the player.

Model code (mostly generated by Blockbench):

public class CustomArmorModel extends BipedModel<LivingEntity> {
	private final ModelRenderer Head;
	private final ModelRenderer Body;
	private final ModelRenderer RightArm;
	private final ModelRenderer LeftArm;
	private final ModelRenderer RightLeg;
	private final ModelRenderer LeftLeg;

	public CustomArmorModel() {
		super(1);
		textureWidth = 64;
		textureHeight = 64;

		Head = new ModelRenderer(this);
		Head.setRotationPoint(0.0F, 0.0F, 0.0F);
		Head.setTextureOffset(32, 0).addBox(-4.0F, -8.0F, -4.0F, 8.0F, 8.0F, 8.0F, 0.5F, false);

		Body = new ModelRenderer(this);
		Body.setRotationPoint(0.0F, 0.0F, 0.0F);
		Body.setTextureOffset(16, 32).addBox(-4.0F, 0.0F, -2.0F, 8.0F, 12.0F, 4.0F, 0.25F, false);
		Body.setTextureOffset(0, 0).addBox(-1.0F, 2.0F, 3.0F, 1.0F, 1.0F, 1.0F, 0.0F, false);
		Body.setTextureOffset(40, 32).addBox(-8.0F, 0.0F, -2.0F, 4.0F, 12.0F, 4.0F, 0.25F, false);

		RightArm = new ModelRenderer(this);
		RightArm.setRotationPoint(-5.0F, 2.0F, 0.0F);
		

		LeftArm = new ModelRenderer(this);
		LeftArm.setRotationPoint(5.0F, 2.0F, 0.0F);
		LeftArm.setTextureOffset(48, 48).addBox(-1.0F, -2.0F, -2.0F, 4.0F, 12.0F, 4.0F, 0.25F, false);

		RightLeg = new ModelRenderer(this);
		RightLeg.setRotationPoint(-1.9F, 12.0F, 0.0F);
		RightLeg.setTextureOffset(0, 32).addBox(-2.0F, 0.0F, -2.0F, 4.0F, 12.0F, 4.0F, 0.25F, false);

		LeftLeg = new ModelRenderer(this);
		LeftLeg.setRotationPoint(1.9F, 12.0F, 0.0F);
		LeftLeg.setTextureOffset(0, 48).addBox(-2.0F, 0.0F, -2.0F, 4.0F, 12.0F, 4.0F, 0.25F, false);
	}


	@Override
	public void render(MatrixStack matrixStack, IVertexBuilder buffer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha){
		Head.render(matrixStack, buffer, packedLight, packedOverlay);
		Body.render(matrixStack, buffer, packedLight, packedOverlay);
		RightArm.render(matrixStack, buffer, packedLight, packedOverlay);
		LeftArm.render(matrixStack, buffer, packedLight, packedOverlay);
		RightLeg.render(matrixStack, buffer, packedLight, packedOverlay);
		LeftLeg.render(matrixStack, buffer, packedLight, packedOverlay);
	}
}

Whats wrong there? And are there other ways to make models, better than Blockbench?
