Abstract
A visco-elastic or soft weight is disclosed, made from a core comprising a particulate weight-adding agent substantially homogeneously dispersed within a visco-elastic material and a cover surrounding the core. A novel weighted visco-elastic composition comprises a visco-elastic material comprising 77-97% plasticizer, 3-15% resin, 0-2% thixotropic thickening agent, 0-2% stabilizer, 0-2% stabilizer enhancer, and 0-2% surfactant and a particulate weight-adding agent in a ratio of weight-adding agent to visco-elastic material of between 1:10 and 2:1.
Claims5
A visco-elastic weight comprising:
- (a) a core of weighted visco-elastic material comprising:
- (i) a particulate weight-adding agent substantially homogeneously dispersed within a visco-elastic material;
- and
- (b) a covering surrounding the core wherein said core has a generally annular shape and the weighted visco-elastic material and covering are capable of elastic stretching to the extent necessary for the weight to slip over a hand or foot and remain in place on an adjoining wrist or ankle during exercise movement.
