The invention relates to a sport equipment, whose primary aspect is endurance training. Another objective of the invention, apart from increasing endurance, is to minimize the risk of injury during and after practices. The invention has a comfortable, tailor-made design shell (1), filled with weight filler (2). The device provides a high degree of freedom to the user, because it does not obstruct the hands and legs while in use. The size of shell (1) is adapted to the user, such that the user can adjust to required size on the neck portion of shell (1), and the equipment takes on an endless shape. Furthermore, by closing the equipment, a 3 dimensional space curve is formed by around the longitudinal axis (4) of human body and the weight filler (2) is placed in sections along the direction of longitudinal axis (4) of equipment.

1. A sport equipment to improve physical fitness of a user, the sport equipment having an open state with a snake-like shape and a closed state with a loop-like shape, the sport equipment having a longitudinal axis (4) extending along the snake-like shape in the open state and along the loop-like shape in the closed state, the sport equipment further comprising at least a partially closed flexible shell (1) with uniform outer surface of catch-free design defining said snake-like shape, a weight filler (2) in bulk arranged within the shell (1) along and in parallel with the longitudinal axis (4), and at least one opening/closing section (3) adjustable in length along the longitudinal axis (4), the opening/closing section (3) of the sport equipment is configured to provide the loop-like shape of endless construction to said sport equipment in the closed state; wherein the loop-like shape of the equipment in the closed state corresponds to a 3-dimensional out-of-plane space curve when fitting the equipment around a spinal line of the user's body, the weight filler (2) is arranged in sections along the direction of the longitudinal axis (4) of the equipment, said weighted sections located symmetrically along the longitudinal axis (4) of the equipment and apart from the opening/closing section (3). 2. The equipment of claim 1, wherein the longitudinal axis (4) of the equipment in the closed state runs from the back occiput (5) of the user's body and under armpits of the user's body when fitting the equipment around the spinal line of the user's body. 3. The equipment of claim 1, comprising two sections of weight fillers (2) with a flexible bond (9) therebetween. 4. The equipment of claim 3, wherein the flexible bond (9) comprises a second opening/closing section (3) adjustable in length. 5. The equipment of claim 1, wherein the equipment is essentially made of two identical mirrored halves. 6. The equipment of claim 5, wherein the weight fillers (2) in the two halves are of the same volume. 7. The equipment of claim 1, wherein the weight filler (2) is sand, gravel, balls, pellets, granules, powder, gel, liquid, or a mixture thereof. 8. The equipment of claim 1, wherein the shell (1) is provided with an opening (10) configured to insert the weight filler (2) into the shell (1). 9. The equipment of claim 8, wherein the shell (1) is formed as two armil parts (12, 13) adapted to overlap one another in the region where the opening (10) is located to hinder the weight filler (2) from slipping out of the shell (1) in the closed state. 10. The equipment of claim 1, wherein the 3-dimensional out-of-plane space curve, in the closed state, essentially corresponds to the contour of a sewing line of a baseball ball. 11. A method for increasing and/or maintaining physical fitness of a human user, said method comprising the human user wearing the equipment of claim 1 in the closed state of the equipment on the user's upper body with the opening/closing section near the user's occiput, and the weight filler extending over and in front of the user's shoulders and behind the back of the user. 12. The method of claim 11, wherein the equipment is located on the back of the user in regions above the user's kidneys. 13. The method of claim 11, wherein the weight filler is worn symmetrically on the user's body by spinal line of the user. 14. The method of claim 11, wherein the equipment is worn by the user during exercise. 15. The method of claim 11, wherein a distance between the center of gravity of the equipment and the user's center of gravity is at 20% or less than the user's body height.
