Abstract

An exercise apparatus for performing an armless push-up allows a user to engage in gravity-driven, resistance exercise with improved pectoral isolation and range of motion as compared to known push-up devices. The exercise motion is performed using a yoga-inspired, bent-elbow plank position by a prone (face-down) user. The user places each forearm on a trolley mounted at the top of opposed rails that are inclined toward an elevated centerline. As the trolleys move down the opposed inclined rails, the user'"'"'s chest descends down; and as the user pinches his elbows together using the pectoralis muscles, the trolleys move up the inclined rails again. Gravity imparts a centered user balance, and the resistance can be varied, such as by changing the incline of the rail assemblies, changing the weight associated with the user, or by adding resistance to the trolley movement.

Claims

1. An exercise apparatus for performing a bent-elbow plank position push-up comprising:

two upwardly inclined linear rail assemblies meeting at an apical midpoint and

two moveable trolleys, wherein

each rail assembly is engaged with a moveable trolley,

each trolley is independently operable,

each trolley comprises an armrest member sized and configured to engage with a forearm of a human user, and

each armrest member is rotatable with respect to the trolley and is rotatable around a central longitudinal axis formed by the user'"'"'s forearm.

2. The exercise apparatus according to claim 1, wherein the rail assemblies are each inclined toward the apical midpoint at an angle of between about 1°

and about 30°

.

3. An exercise apparatus for performing a bent-elbow plank position push-up comprising:

two upwardly inclined linear rail assemblies meeting at an apical midpoint and

two moveable trolleys, wherein

each rail assembly is engaged with a moveable trolley,

each trolley is independently operable and slidable up and down a rail assembly,

each trolley comprises an armrest member sized and configured to engage with a forearm of a human user, and

each armrest member is rotatable with respect to the trolley and is rotatable around a central longitudinal axis formed by the user'"'"'s forearm.

4. An exercise apparatus for performing a bent-elbow plank position push-up comprising:

a first rail assembly having two co-planar linear inclined rail members and a second rail assembly having two co-planar linear inclined rail members, the elevated ends of the two rail assemblies meeting at an apical midpoint, wherein the first rail assembly and the second rail assembly are symmetrical and hinged;

a right-handed trolley mounted to the first rail assembly and slidable thereupon; and

a left-handed trolley mounted to the second rail assembly and slidable thereupon;

wherein

each trolley comprises an armrest member sized and configured to engage with a forearm of a human user, the armrest member being rotatable with respect to the trolley and being rotatable around a central longitudinal axis formed by the user'"'"'s forearm.
