Abstract
The gluteal muscles are exercised using a vertical lift strategy. It is much improved over common buttock exercise methods of sitting, laying, squatting or pushing weight horizontally. The (GM) power lift apparatus is operated in a standing position. Using commercial exercise design methods, the GM power lift apparatus is designed around the lifting of a variable weight plate stack. Three pullies redirect the pull force of the weight plate under the operator's foot as lift on the gluteus maximus muscle group. The new standing design allows improved muscle agitation by making the gluteus maximus muscle group lift a vertical payload, the maximum angle of force. During the power lift stroke, the foot, leg and back muscles are vertically synchronized to horizontal stretched forearms providing greater strength management.

DETAILED DESCRIPTION OF INVENTION
[0012] The Gluteus Maximus Power Lift Apparatus FIG. 1 is designed from standard steel stock materials used in commercial exercise equipment. The manufacture of this product is well suited for welding. The cylindrical tube arrays 1 and 2, the vertical steel rods 7 and square bars usage 8 creates the frame for the apparatus. The apparatus has a step-up platform 4 to allow for parts assembled underneath. The weight plate system 3 is a standard assembly used in a selected weight system. The foot assembly 5 is formed from a mold. Of cast aluminum, the foot assembly 5 is a single piece critical in the delivery of lift power to the operator. Steel cable encapsulated in vinyl 6 is standard usage in the motion of the weights. There are a few specialized rubber 33 or rubber like substances on surfaces to absorb the bumping metal parts.
[0013] The (GM) power lift apparatus FIG. 1 distinguishes itself from all other gluteal and buttock methods of exercise performing a vertical lift on the gluteus maximus muscle while in a normal standing position. Other methods of delivering exercise to these areas are less effective as bending, stooping and laying down seem contrary to the lift potential of the gluteal group.
[0014] The tube arrays 1, 2 are functional and ornamental enabling a varied selection of height and distance to secure the operator's limbs during the power lift. This feature keeps both arms and hands flexed to balance the various stresses inherent in weight lifting. As the focal point of counter balance, the array tubes mount hand grips, FIG. 6, 30 inside the tubes with a pin lock FIG. 6, 31 that fits into synced holes. The hand grips mount in up or down positions to cover a region that the operator may need to get a good grip. There is a tube array for each hand. Operator selects a position on the tube array FIG. 1, 1 pushing the hand grip FIG. 6 into a tube and secure it with the pin lock FIG. 6, 31 provided on each grip.
[0015] A standard exercise design, the weight plate system FIG. 2 is traditional to include two symmetrical vertical slide bars 7, a center attached cable 6 secured with a holed sleeve 9. With weight plate 13 lifted, the holed sleeve 9 is installed underneath and aligned with first sleeve hole. A plug 14 with threads is screwed into the weight plate 13 on the select side where there is a threaded hole 12, locks the holed sleeve to the weight plate 3 and to the motion of the vertical steel bars 7. Next a cable fastener screw/nut 11 is screwed into the top of the holed sleeve poking out and nut is screwed down to lock the cable 6 to the weight plate 13, the holed sleeve 9 and the cable pulley system 6.
[0016] The weight plates 3 are labeled by weight increase 12 so the operator can set various weight loads. By pushing a metal pin lock 10 thru the weight plate selected 12 the corresponding holed sleeve 9 is locked as well. When the operator begins the power lift stroke all the weight plates above the pin lock 10 become part of the lifting activity. With these components working together the operator can focus on a safe and fruitful exercise.
[0017] The (GM) power lift apparatus has a system of pulleys FIG. 3 to redirect the forces of lift from the foot assembly to the selected weight platter. Pulley A 15 and pulley B 16 are positioned underneath apparatus platform 4 directly where the cable 6 comes through the platform to connect to the foot assembly. When demanded Pulley A 15 turns the cable 90 degrees from a vertical force to a horizontal force. Thereafter a second pulley, B 16 positioned partially away and free of the platform 4 turns the cable force direction upward toward the upper frame of the apparatus. Pulley Cm 17 positioned in the upper frame is both aligned with the center of the weight platter system 3 and the vertical cable 6 from pulley B 16. Pulley C 17 facilitates a 180 degree direction change in the lift force such that the lift force is now directly on the selected weights 12. With the lift force initiated by the Gluteal muscles and transferred from the foot assembly 5 connection to the cable system 6 redirected by pulley A 15 and pulley B 16 to pulley C 17, the cable system 6 of the (GM) power lift apparatus lifts the selected weight plates 12 so a payload selected by the operator creates a lift exercise.
[0018] The foot assembly FIG. 4 is a critical part of the gluteus maximus power lift apparatus. It is a single piece of aluminum or lighter metal formed by mold. On the bottom heel area is a protrusion that is a partial sphere 20. Two different size holes are drilled in this bump, from above and below. The hole below is suited for threading cable wire 6 thru it. The above drilled hole is larger than the hole below. When the cable 6 is pulled thru from the top side to the side below. At the end of the cable wire 6, one side of it has a metal knot 19 which is larger than the hole for the cable. That stops the cable 6 from going all the way out. At that point the foot assembly 5 is connected to the cable system 6. There is just enough room left for a small screw cap 18 over the cable notch 19 to protect the users from any injuries.
[0019] More pressure and stress is on the foot assembly FIG. 5 than any other place on the body. To protect the foot, a foot strap of different layers of manufactured materials keep the foot safe; kevlar creates the outer structure 21. Underneath and sewn onto the kevlar is two inches of memory foam 22 in direct contact with the operator's footwear and ankle. Studs 23, 25 secure the foot strap to the side of foot assembly FIG. 7, 25, 26, 27. The strap is placed over the foot. Placing the foot strap over the foot, the operator must loop the front strap through the loophole FIG. 7, 28 designated to secure the mid toe and ball of foot and Velcro the reversed flap down 36. The ankle flap 24 pulls back and down and is looped through FIG. 7, 29 to secure the ankle and heel. With that the operator is free to enjoy exercising the gluteal using the power lift.
[0020] FIG. 6 is the foot assembly that secures the foot so that the lifting of weight will be injury free. Studs 25, 26, 27 are used to secure the foot strap to the foot assembly. Loops 28 and 29 are used by the Kevlar and Velcro straps to secure the foot.
[0021] When an exerciser is ready to operate the gluteus maximus powerlift apparatus, the hand grips FIG. 7 must be adjusted to the operators arm and forearm lengths. There are two hand grips which are pushed into the tubes arrays of FIG. 1. The hand grips are secured with lock pin 31. An exerciser should then stand center on the platform FIG. 1, 4 facing so the hands are nearest the tube arrays on both sides of the body. While your arms are hanging down, raise your forearm to a horizontal level. This is the ideal height and distance of the arm for counter balance. Note the position of your hand where it is closest to a tube in the tube array FIG. 1. If your forearm is below the lowest tubes horizontal, slide the hand grip in the tube upside down at that position. If the forearm is above the lower horizontal tubes slide the hand right-side up in the tube. Exerciser must perform this procedure for the other arm too.
[0022] With all prep activities completed, the operator is ready to enjoy exercising the gluteal muscles.
[0023] The Gluteus Maximus Power Lift Apparatus is constructed to provide a repetitive vertical lift exercise stroke on the gluteal muscles from a standing positon using hand grips for a counter balance.
[0024] The Gluteus Maximus Power Lift Apparatus is designed to deliver a repetitive vertical lift exercise stroke on the gluteal muscles from weight attached to a cable underneath the heel of a foot assembly designed to immobilized the operator's foot.
