The present disclosure is directed to an exercise device that makes push-ups more physically challenging by reducing the area of contact that the push-up device makes with a surface while in use. A distal end of the device has a minimal radius of curvature, such that the surface area of the device in contact with the ground is minimized, thereby inducing instability. The user is challenged to overcome the inherent instability of the push-up device, thereby recruiting more muscle groups, placing higher demand on involved muscle groups, and practicing balance and proprioception. Additionally, by elevating the user's hands above the ground, the device can also enable the user's chest to move below the plane of the palms of his or her hands, thus inducing a larger range of motion with each push-up and further challenging the user's muscles.
