Abstract: An exercise machine is provided. The exercise machine may include a frame, an adjustment assembly coupled to the frame and selectively movable relative thereto, a foot linkage arranged to reciprocally move in a closed loop path, and a handle linkage arranged to reciprocally move in a defined path. The adjustment assembly may include a pivot axis. The foot linkage may be pivotably coupled to the adjustment assembly at the pivot axis such that selective movement of the pivot axis relative to the frame alters the closed loop path of the foot linkage in use.

Abstract: Systems and methods for generating a 360 degree mixed virtual reality environment that provides a 360 degree view of an environment in accordance with embodiments of the invention are described. In a number of embodiments, the 360 degree mixed virtual reality environment is obtained by (1) combining one or more real world videos that capture images of an environment with (2) a virtual world environment that includes various synthetic objects that may be placed within the real world clips. Furthermore, the virtual objects embedded within the 360 degree mixed reality environment interact with the real world objects depicted in the real world environment to provide a realistic mixed reality experience.

Abstract: An adaptive training system can determine a finite work capacity and critical power and use those determinations to generate an adaptive training programs for workout parameters. To determining a finite work capacity and critical power, the adaptive training system can receive workout data; generate data points by determining, for each workout, a maximum amount of work done for each of multiple time window sizes; fit these workout data points to a function; and determine a critical power and finite work capacity based on the fitted function. Once the adaptive training system has determined a critical power and finite work capacity, the adaptive training system can use them to generate an adaptive training program by keeping a function defined by a set of workout parameters below an ability function that is based on the critical power and finite work capacity.

Abstract: A stationary exercise machine may include reciprocating hand members, such as handles, and/or reciprocating foot members, such as foot pedals. The reciprocating hand members may be operative to apply a first moment to a crankshaft, and the reciprocating foot members may be operative to apply a second moment to the crankshaft. The second moment may be different than the first moment. The reciprocating foot members may cause a user's feet to move along a closed loop path that is substantially inclined, such that the user's foot motion simulates a climbing motion more than a flat walking or running motion. The reciprocating hand members may be configured to move in coordination with the foot members via a linkage operatively coupling the hand members with the foot members. A resistance mechanism may apply resistance to crankshaft rotation, and the resistance mechanism may be adjustable while the user is using the machine.
