Habit Strength reflects the consistency in performing the habit. If users diligently act on their habit, their Strength remains full. However, neglecting the habit by not taking action or failing will result in losing 1 Strength point each day. Completing the habit the next day will restore the Strength bar.

If a user loses all three bars of their Habit Strength, they will be eliminated from the challenge. This mechanism encourages users to stay on track and remain consistent with their habits.
