Systems and methods are disclosed for providing a user a training load schedule for peak performance using earphones with biometric sensors. In one embodiment, the system includes earphones, including: speakers a processor a heartrate sensor electrically coupled to the processor and a motion sensor electrically coupled to the processor. In this embodiment, the system also includes a memory coupled to a processor and having instructions stored that, when executed by the processor: display on a display an initial load schedule stored in a memory to the user calculate a fatigue level of the user based on signals generated by the heartrate sensor modify the initial load schedule based on the calculated fatigue level to create a dynamic load schedule for the user and display on the display the dynamic load schedule to the user.
