Abstract: A social media system includes processing hardware and a memory storing software code. The processing hardware executes the software code to receive beneficiary data identifying an entity selected by a system user to receive a donation, obtain a user profile of the system user, verify that the selected entity is a qualified charitable entity, and determine, in response to completing the verification, and using the user profile and the beneficiary data, one or more candidate contributor(s) of the donation. The processing hardware further executes the software code to identify one or more influencer(s) to promote the donation, obtain, from at least one of the identified influencer(s), an endorsement of the donation, issue a challenge to each of the candidate contributor(s) to contribute the donation, and inform the selected entity, in response to receiving an acceptance of the challenge from at least one of the candidate contributor(s), of the donation.

Abstract: An exercise apparatus includes a base having a support stand upstanding therefrom. A pair of spaced apart foot rails each have a first end and opposing second end. The second end of each foot rail rests on the base of the frame. A pair of stroke rails each have a first end and an opposing second end. The first end of each stroke rail is slidably attached to the support stand of the frame while the second end of each stroke rail is hingedly attached to a corresponding foot rail. An axle of a crank is rotatably mounted to the support stand. A pair of crank arms each orthogonally project from the corresponding ends of the axle in opposing directions. Each remote end of the crank arm is rotatably mounted to a corresponding stroke rail between the ends thereof.
