## What is 100 Days Locked In?

100 Days Locked In helps you commit to a focused 100-day fitness challenge and track the daily habits that make the challenge work.

Create your challenge, follow a structured training plan, and check off the essentials each day: workout, cardio, steps, macros, no alcohol, and progress check-ins. The app turns those habits into a daily score so you can see whether you are staying locked in.

Progress tools help you log body weight, body fat, photos, notes, and consistency over time. Social features let you follow friends, join groups, view leaderboards, share Bam Cam progress photos, and keep accountability visible without making everything public.

Built for small private groups, early fitness challenges, and anyone who wants a simple way to stay accountable for 100 straight days.
