consistency in the gym

As a college student, I want a tool to allow me to track my consistency in the gym throughout the week and compete with my friends who also have the same goal because I want to exercise consistently.

The issue names no files, tests, or entry points and only describes a desired gym-tracking and friend-competition tool. Start by inspecting the repository structure and existing project behavior, then clarify the tracking, comparison, and completion requirements before implementation. Done should mean the agreed feature works end to end and is covered by appropriate tests.
