A row boat for rowing training includes a hull including a bottom and four sidewalls, and a pair of oars connected to opposing sidewalls, each oar including a handle and an oar scoop disposed as an end of the handle, wherein the oars are configured to rotate about a first axis of rotation to move the oars during a pull phase and a flex phase of a rowing stroke, and wherein the oars are configured to rotate about a second axis of rotation to change an angular orientation of the oar scoop in water during the pull phase and the flex phase.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.
