TECHNICAL FIELD OF INVENTION

[0002] The present invention relates to a weightlifting apparatus, and a method of using the apparatus. One embodiment of the invention comprises a weightlifting bar having moveable hand grips, and means for providing resistance against inward movement of the hand grips.

BACKGROUND OF INVENTION

[0003] Weightlifting is a popular and effective means for developing muscle strength and improving overall health and fitness. Barbells and dumbbells are commonly used to develop muscles in the upper body, and in particular the pectoralis muscle. Barbells feature equal weights positioned on opposite ends of a single long bar that is gripped by both hands of the user, while dumbbells have a short bar gripped by only one hand of the user. Barbells provide greater stability for the user than dumbbells, and therefore the user can typically lift more weight on a single barbell than with two dumbbells. However, dumbbells generally allow for a greater range of motion for the user than a barbell, which requires the user to keep both hands in place on a single bar. Accordingly, there is a need for a weightlifting apparatus providing stability similar to that of a barbell, while allowing for a greater variety of motion than traditional barbells.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION AND BEST MODE

[0031] A weightlifting apparatus according to a preferred embodiment of the invention is illustrated in FIG. 1, and shown generally at reference numeral 10. The weightlifting apparatus 10 comprises a substantially cylindrical elongate bar 12, a pair of substantially cylindrical hand gripping members 20, 30 positioned on the bar 12, and a pair of resistance members 25, 35 positioned on the bar 12.

[0032] The bar 12 can be made of a metal such as steel, aluminum or other suitable material. The bar 12 can have the length and diameter of a standard barbell. The bar 12 can support a plurality of standard two inch weight plates at opposite ends 14, 16 of the bar. The apparatus 10 includes stop members proximate opposite ends 14, 16 of the bar 12 to maintain the weight plates on the bar 12 and prevent the weight plates from sliding on the bar 12. The stop members can be enlarged end sleeves 18, 19 formed on the bar 12 proximate opposite ends 14, 16 of the bar 12, as shown in FIG. 1. Alternatively, the stop members can be removable weight collars positioned proximate opposite ends 14, 16 of the bar 12 to maintain weight plates on the bar 12.

[0033] Hand gripping members 20 can be comprised of an elongate center sleeve section 21 and a pair of enlarged guard sections 22, 23 at opposed ends of the center section 21, as shown in FIG. 2. Likewise, the other hand gripping member 30 can be comprised of an elongate center sleeve section 31 and a pair of enlarged guard sections 32, 33 at opposed ends of the center section 31. The hand gripping members 20, 30 can be made of a metal such as steel, aluminum or other suitable material. Each of the hand gripping members 20, 30 can be approximately seven inches long.

[0034] The hand gripping members 20, 30 can be hollow and have an inner diameter slightly greater than the outer diameter of the bar 12. The hand gripping members can be telescopically positioned on the bar 12. As such, the hand gripping members 20, 30 can slide axially on the bar, and can rotate about the bar. The hand gripping members 20, 30 are positioned on opposite sides of the center 15 of the bar 12, approximately equal distance from the center 15, as shown in FIG. 1.

[0035] The apparatus 10 includes means for providing resistance to inward movement of the hand gripping members 20, 30. The means for providing this resistance can be a pair of resistance members 25, 35 positioned on the bar 12, as shown in FIG. 1. Each of the resistance members 25, 35 can be comprised of a spring loaded tension coil. The spring loaded tension coils 25, 35 can be made of a metal, such as steel or aluminum, or other suitable material. The coils 25, 35 are positioned on the bar 12 proximate the hand gripping members 20, 30, respectively, as shown in FIG. 1. One coil 25 is positioned between the center 15 of the bar 12 and the left hand gripping member 20, and the other coil 35 is positioned between the center 15 and the right hand gripping member 30, as shown in FIG. 1.

[0036] A plurality of stop members 26, 27, 36, 37 are positioned on the bar 12 to restrict movement of the hand gripping members 20, 30 and the coils 25, 35. Each of the stop members can be comprised of a collar that is releasably attached to the bar 12 by a locking screw 40, shown in FIG. 2. The collars 26, 27, 36, 37 are held in place on the bar 12 by tightening the locking screws 40. Inner collars 26, 36 are positioned on the bar 12 between the center 15 and the hand gripping members 20, 30, respectively, as shown in FIG. 1. As such, the coils cannot move inwardly beyond the inner collars 26, 36. Outer collars 27, 37 are positioned on the bar 12 to the outside of the hand gripping members 20, 30. Left outer collar 27 is positioned between the left end 14 of the bar 12 and the left hand gripping member 20, and the right outer collar 37 is positioned between the right end 16 of the bar 12 and the right hand gripping member 30. As such, the left hand gripping member 20 cannot move outwardly on the bar 12 beyond the left outer collar 27, and the right hand gripping member 30 cannot move outwardly on the bar 12 beyond the right outer collar 37.

[0037] The left hand gripping member 20 and the left coil 25 are maintained on the bar 12 between the inner collar 26 and outer collar 27, as shown in FIG. 2. Likewise, the right hand gripping member 30 and the right coil 35 are maintained on the bar 12 between the inner collar 36 and outer collar 37. If desired, the user can release the collars 26, 27, 36, 37 by unscrewing the locking screws 40, and the collars 26, 27, 36, 37 can be moved to different positions on the bar 12 to adjust to the comfort and preferences of the user. When the collars 26, 27, 36, 37 are in the desired position, the collars can be re-secured to the bar 12 by tightening the locking screws 40.

[0038] As shown in FIG. 2, the inner guard section 22 of the left hand gripping member 20 is adjacent to the left coil 25, and the outer guard section 23 of the left hand gripping member 20 is adjacent to the outer collar 27. Likewise, the inner guard section 32 of the right hand gripping member 30 is adjacent to the right coil 35, and the outer guard section 33 of the right hand gripping member 30 is adjacent to the outer collar 37. When the hand gripping members 20, 30 are moved inwardly toward the center 15 of the bar 12, the spring loaded coils 25, 35 provide resistance against the hand gripping members 20, 30.

[0039] A method of using the weight lifting apparatus 10 according to a preferred embodiment of the invention is illustrated in FIGS. 3-5. As shown in FIG. 3, weight plates 50 are positioned at opposite ends 14, 16 of the bar 12 proximate the end sleeves 18, 19. The user's hands 80 grip the hand gripping members 20, 30, with the hand gripping members 20, 30 in their natural position at rest on the bar 12. The user lifts the bar 12 upwardly in a bench press type motion, while simultaneously sliding the handles 20, 30 inwardly toward the center 15 of the bar 12, as shown in FIG. 4. The spring loaded tension coils 25, 35 provide resistance against the inward movement of the handles 20, 30 as the user pushes the handles 20, 30 inwardly. This provides isolation and contraction of the user's pectoralis muscles. The pectoralis muscles of the user are simultaneously worked at two distinct angles by two distinct exercise motions. When the user's bench press reaches full extension, the user can slowly release the pressure on the handles 20, 30 and slide the handles 20, 30 outwardly back to their natural position, as shown in FIG. 5. The user can then lower the apparatus 10 back to the position shown in FIG. 3, and repeat the above steps until the desired number of repetitions are done.

[0040] The weightlifting apparatus 10 can be used in a variety of exercises. For example, the apparatus can be used in a front raise type exercise. Before lifting the bar 12, the user should firmly grip the handles 20, 30, while standing or seated on an incline bench. The handles 20, 30 are pushed inwardly toward the center 15 of the bar 12. This isolates and contracts the muscles. The user raises the bar 12 in front of himself in a straight, locked arm motion. The user slowly releases pressure to the handles 20, 30 when the bar is at shoulder height. The user lowers the bar 12 back down in front of himself in a straight, locked arm motion. These steps can be repeated until the desired number of repetitions are done.

[0041] As shown in FIGS. 6 and 7, the user can rotate the hand gripping members 20, 30 about the bar 12. This can help develop muscles in the user's wrist, and add to the variety of exercises that can be accomplished with the apparatus 10.

[0042] The weightlifting apparatus 10 helps facilitate muscle isolation during work outs, and enables the user to perform two different type workouts at the same time in a single exercise. Because multiple exercise motions can be performed simultaneously, the apparatus 10 can shorten work out times, and provide a more intense workout than a standard barbell.

[0043] A weightlifting apparatus and method of using same are described above. Various changes can be made to the invention without departing from its scope. The above description of various embodiments and best mode of the invention are provided for the purpose of illustration only and not limitation--the invention being defined by the claims and equivalents thereof.
