Abstract
An exercise device can include a handle having a handle axis and a handle weight. A head can be removably coupled to a distal end of the handle with a single fastener adjacent a proximal end of the head. The head can have a head weight and can be axe-shaped. A distal end of the head can be blunt. A portion of each of the proximal and distal ends can be planar.
Claims17
An exercise device, comprising:
- a handle having a handle axis and a handle weight;
- a head removably coupled to a distal end of the handle with a single fastener adjacent a proximal end of the head, the head comprises a head weight, the head is axe-shaped, a distal end of the head is blunt, a portion of each of the proximal and distal ends of the head is planar, the head comprises a metallic core that is overmolded with a polymer, wherein the head weight is distributed asymmetrically with respect to a geometric center of the head in at least one of x, y and z-axes of the head;
- and
- a total weight of the exercise device is at least about 2 pounds.

An exercise device, comprising:
- a handle having a handle axis, a handle proximal portion, a handle middle portion and a handle distal portion;
- a head coupled to the handle, and the head comprises a head weight, wherein the head is axe-shaped and a distal end of the head is blunt, wherein the head comprises a core that is over-molded with a polymer has been inserted after;
- wherein
- when the handle distal portion is gripped in a hand of the user and the handle is vertical, a total magnitude of force applied to the hand by the exercise device is at least about 10% greater than the head weight, and not greater than about 100% of the head weight;
- when the handle middle portion is gripped in the hand of the user and the handle is vertical, a total magnitude of force applied to the hand by the exercise device is at least about 25% greater than the head weight, and not greater than about 150% of the head weight;
- and
- when the handle proximal portion is gripped in the hand of the user and the handle is vertical, a total magnitude of force applied to the hand by the exercise device is at least about 50% greater than the head weight, and not greater than about 200% of the head weight;
- and
- a wrist strap extending from the handle and configured to be connected to a wrist of the user to restrain the exercise device during chopping motions by the user.
