Abstract

A glute hamstring developer exercise machine includes a vertical post extending from a lower end to an upper end; a user body support system coupled to the vertical post, the user body support system having one or more pads to support the user in a plurality of positions; and a primary frame supporting the one or more pads and extending substantially from the vertical post; at least one weight arm positioned substantially underneath the one or more pads, the at least one weight arm is to be operated by the user to perform one or more exercises.

Claims (65)

1 . A glute hamstring developer exercise machine, comprising:

a vertical post extending from a lower end to an upper end;

a user body support system coupled to the vertical post, the user body support system having:

one or more pads to support the user in a plurality of positions; and

a primary frame supporting the one or more pads and extending substantially from the vertical post;

at least one weight arm positioned substantially underneath the one or more pads, the at least one weight arm configured to be operated by the user to perform one or more exercises;

a vertical bracket connected to the vertical post via one or more locking pins;

a linear guide rail attached to the vertical bracket;

at least one linear guide block coupled to the linear guide rail and configured to traverse along the linear guide rail; and

a trolley assembly attached to the at least one linear guide block such that the trolley assembly can traverse along the linear guide rail via the at least one linear guide block;

wherein the primary frame is attached to the trolley assembly such that the user body support system is configured to move with the trolley assembly.

2 . The glute hamstring developer exercise machine of claim 1 , further comprising:

a bottom bracket positioned on the lower end of the vertical post;

the at least one weight arm includes:

a first weight arm coupled to the bottom bracket via a first hinged connection, a second hinged connection and a third hinged connection, the first, second, and third hinged connections allowing the first weight arm to move within three planes during operation; and

a second weight arm coupled to the bottom bracket;

wherein the first weight arm and the second weight arm are length adjustable and extend from the bottom bracket to a weight receiving end; and

wherein the first weight arm and the second weight arm are configured to be lifted by the user as the user is supported by the user body support system.

3 . The glute hamstring developer exercise machine of claim 1 , further comprising a reverse hyper bar extending downward from the user body support system, the reverse hyper bar having a handle configured for operation by the user.

4 . The glute hamstring developer exercise machine of claim 3 , further comprising a bar and dumbbell stand attachment coupled to the reverse hyper bar, the bar and dumbbell stand attachment having a first pair of hooks and a second pair of hooks, the first pair of hooks and the second pair of hooks configured to support a bar or dumbbell.

5 . The glute hamstring developer exercise machine of claim 4 , wherein the bar and dumbbell stand attachment further comprises:

a bracket attached to the reverse hyper bar;

a first member extending from the bracket and supporting the first pair of hooks, the first pair of hooks coupled to the first member via an adjustment plate such that the first pair of hooks is adjustable in a first plane; and

a second member extending from the bracket and supporting the second pair of hooks.

6 . The glute hamstring developer exercise machine of claim 5 , wherein the first pair of hooks is further coupled to the first member via a second adjustment plate such that the first pair of hooks is adjustable in a second plane.

7 . The glute hamstring developer exercise machine of claim 3 , further comprising a secondary dumbbell attachment having a bracket configured to couple the secondary dumbbell attachment to the reverse hyper bar, the secondary dumbbell attachment further having:

a first member extending from the bracket;

an adjustment plate attached to the first member;

a first pair of bumpers coupled to the adjustment plate and the first member such that the first pair of bumpers is configured to be selectively positioned via the adjustment plate; and

a first hook coupled to the first pair of bumpers.

8 . The glute hamstring developer exercise machine of claim 1 , wherein the trolley assembly further comprises:

a main bracket mounted to the at least one linear guide block, the main bracket forming an accessory attachment insert configured to receive one or more accessories;

at least one gas spring configured to provide counter force against the user body support system; and

one or more handles configured to aid a user in manipulation of the trolley assembly.

9 . The glute hamstring developer exercise machine of claim 8 , further comprising a vertical gas spring attached to the vertical bracket and configured to provide counterweight against a weight supported by the vertical bracket.

10 . The glute hamstring developer exercise machine of claim 1 , further comprising a foot and ankle pad assembly coupled to the primary frame.

11 . The glute hamstring developer exercise machine of claim 10 , wherein the foot and ankle pad assembly further comprises:

a base plate mounted to the primary frame via at least one linear bearing;

a vertical member extending from the base plate;

a pair of upper pads coupled to the vertical member; and

a pair of lower pads coupled to the vertical member.

12 . The glute hamstring developer exercise machine of claim 11 , further comprising a base platform positioned behind vertical member and coupled to the base plate.

13 . The glute hamstring developer exercise machine of claim 1 , further comprising:

a first leg support extending from a ground surface to the user body support system;

a second leg support extending from the ground surface to the user body support system; and

a cross bar extending underneath the user body support system and between the first leg support and the second leg support.

14 . The glute hamstring developer exercise machine of claim 13 , wherein the first leg support further comprises:

an extension leg configured to extend a length of the first leg support and lock into place via a pin; and

a threaded leveling mount positioned on a bottom end of the extension leg.

15 . The glute hamstring developer exercise machine of claim 13 , further comprising a step up plate attached to the first leg support.

16 . The glute hamstring developer exercise machine of claim 13 , further comprising a weight arm shelf attached to the first leg support via a hex shaft extending from the weight arm shelf and a hex port attached to the first leg support.

17 . The glute hamstring developer exercise machine of claim 1 , further comprising at least one handle assembly coupled to the at least one weight arm, the at least one handle assembly having a handle for operation by a user.

18 . The glute hamstring developer exercise machine of claim 17 , wherein the at least one handle assembly further comprises a carriage configured to adjustably secure at a distance away from the at least one weight arm.

19 . The glute hamstring developer exercise machine of claim 18 , wherein the handle is coupled to the carriage via a first hinged connection, a second hinged connection, and a third hinged connection such that the handle can move within three planes of movement.

20 . A glute hamstring developer exercise machine, comprising:
