The device comprises: a pair of tines, each tine comprising an upper end and a lower end; a fork root attached to the upper ends of the pair of tines; and a suspension element attached to and suspending the fork root. The suspension element suspends the fork root and the upper ends of the tines above water comprising a practice area, the lower ends of the tines are submerged in the water of the practice area, and the pair of tines operative to maintaining a position of the swimmer in the practice area. ## Claims ### Claim 1 An aquatic exercise device for assisting a swimmer to practice swimming in place, said device comprising: a pair of tines, each tine comprising an upper end and a lower end, and each tine further comprising a hinge, whereby each hinge enables each tine to be folded so that the lower end of each tine is elevated with respect to the upper end; a fork root attached to the upper ends of the pair of tines; a suspension element attached to and suspending the fork root; and whereby the suspension element suspends the fork root and the upper ends of the tines above water comprising a practice area, the lower ends of the tines are submerged in the water of the practice area, and the pair of tines operative to maintaining a position of the swimmer in the practice area. ### Claim 2 (depends on 1) The aquatic exercise device according to claim 1, further comprising a base attached to the suspension element. ### Claim 3 (depends on 1) The aquatic exercise device according to claim 1, further comprising a base that is removably attached to the suspension element. ### Claim 4 (depends on 1) The aquatic exercise device according to claim 1, further comprising a base attached to the suspension element, and whereby the suspension element is rotatable with respect to the base. ### Claim 5 (depends on 1) The aquatic exercise device according to claim 1, further comprising a pair of retention elements, and whereby each tine is attached to the fork root using one of the retention elements, and whereby each retention element applies a normalizing force to maintain the position of the tine with respect to the fork root. ### Claim 6 (depends on 1) The aquatic exercise device according to claim 1, further comprising a pair of protective coverings, and wherein each protective covering is applied to of the tines. ### Claim 7 An aquatic exercise device for assisting a swimmer to practice swimming in place, said device comprising: a pair of tines, each tine comprising an upper end and a lower end; a pair of retention elements, the retention elements respectively attached to the upper ends of the tines; a fork root attached to the upper ends of the pair of tines using the respective retention elements; a suspension element attached to and suspending the fork root; and whereby the suspension element suspends the fork root and the upper ends of the tines above water comprising a practice area, the lower ends of the tines are submerged in the water of the practice area, the pair of tines operative to maintaining a position of the swimmer in the practice area, and each retention element applies a normalizing force to maintain the position of each tine with respect to the fork root. ### Claim 8 (depends on 7) The aquatic exercise device according to claim 7, further comprising a base attached to the suspension element. ### Claim 9 (depends on 7) The aquatic exercise device according to claim 7, further comprising a base that is removably attached to the suspension element. ### Claim 10 (depends on 7) The aquatic exercise device according to claim 7, further comprising a base attached to the suspension element, and whereby the suspension element is rotatable with respect to the base. ### Claim 11 (depends on 7) The aquatic exercise device according to claim 7, wherein each tine comprises a hinge, whereby each hinge enables each tine to be folded so that the lower end of each tine is elevated with respect to the upper end. ### Claim 12 (depends on 7) The aquatic exercise device according to claim 7, further comprising a pair of protective coverings, and wherein each protective covering is applied to one of the tines. ### Claim 13 An aquatic exercise device for assisting a swimmer to practice swimming in place, said device comprising: a pair of tines, each tine comprising an upper end and a lower end; a pair of retention elements, the retention elements respectively attached to the upper ends of the tines; a fork root attached to the upper ends of the pair of tines using the respective retention elements; a suspension element comprising a first end and a second end, the suspension element attached to and suspending the fork root at the first end of the suspension element; a base attached to the second end of the suspension element; and whereby the suspension element suspends the fork root and the upper ends of the tines above water comprising a practice area, the lower ends of the tines are submerged in the water of the practice area, the pair of tines operative to maintaining a position of the swimmer in the practice area, and each retention element applies a normalizing force to maintain the position of each tine with respect to the fork root. ### Claim 14 (depends on 13) The aquatic exercise device according to claim 13, wherein the base is removably attached to the suspension element. ### Claim 15 (depends on 13) The aquatic exercise device according to claim 13, wherein the suspension element is rotatable with respect to the base. ### Claim 16 (depends on 13) The aquatic exercise device according to claim 13, wherein each tine comprises a hinge, whereby each hinge enables each tine to be folded so that the lower end of each tine is elevated with respect to the upper end. ### Claim 17 (depends on 13) The aquatic exercise device according to claim 13, further comprising a pair of protective coverings, and wherein each protective covering is applied to one of the tines. ### Claim 18 An aquatic exercise device for assisting a swimmer to practice swimming in place, said device comprising: a pair of tines, each tine comprising an upper end and a lower end; a fork root attached to the upper ends of the pair of tines; a suspension element attached to and suspending the fork root; and whereby the suspension element suspends the fork root and the upper ends of the tines above water comprising a practice area, the lower ends of the tines are submerged in the water of the practice area, each of the tines extending vertically downward into the water, a first one of the tines being horizontally spaced apart from a second one of the tines so as to define a gap therebetween that is configured to receive a neck of the swimmer, and the pair of tines operative to maintaining a position of the swimmer in the practice area by restraining the swimmer at his or her shoulders.
