Clarify User Action: Add Exercise to Training Day

[ShanBell42]

User Confusion

I performed a usability walkthrough of this project for a college class and noticed that there could be a potential source of confusion after creating a new training day. The user may not immediately know that the plus icon is how to add an exercise, only pressing the button hoping it works.

Proposal

Two fixes for this that will be consistent with the rest of the design is to either have mouse-hover text saying "Add Exercise", or replace the plus icon with a button saying the same.
