Fitness tracking devices generate files that store activity data like speed and heart rate. These files are important for monitoring workouts and progress over time. However, you might lose important details about your workouts, like how far you ran or your heart rate, when these files get damaged. Problematic fitness data files can occur for several reasons, such as power loss during recording or incorrect device removal.

Since they carry important stats about your fitness journey, it is very important to repair them and extract the data from them. Hence, this article will explain what these FIT files are and the reasons they get damaged. Furthermore, you will learn about various FIT file repair tool options that ensure your activity data is recovered properly.

Part 1. What Are FIT Files and Their Common Uses?

These are digital records of workout data and contain details like your heart rate and speed while working out. Similarly, these FIT files are created by fitness devices, sports watches, and bike computers to record details of your activities.

Similarly, such files are designed to be shared between different devices and platforms without compatibility issues. Anyhow, let’s see its general uses before discussing the need to repair the FIT file:

• Activity Tracking: These files record various metrics during workouts, such as calories burned during the exercise or the distance traveled while running. Hence, these fitness data files ultimately help users track their physical activity levels.
• Performance Analysis: Athletes use FIT files to analyze performance, such as pace and cadence, which help identify strengths. Additionally, coaches rely on this data to tailor training programs according to these stats.
• Health Monitoring: Since these files can log data related to health, including sleep patterns, they provide insights into overall well-being. Early detection of irregularities can help users take timely medication consultations.
• Route Mapping: Most devices with GPS features store their location information in FIT files, which allows users to review their paths. This feature helps plan future workouts and share routes with others.
• Data Syncing: Due to their compatibility, these files can share your data across multiple platforms and devices. In this way, these fitness files ensure consistency in tracking progress, regardless of the device used.

Part 2. 5 Common Reasons Why FIT Files Become Corrupted

Although they are very useful for tracking your daily activity levels, the files containing your fitness records can get damaged. These are a few reasons that cause these files to become corrupted and demand the need for a FIT file fixer:

• Data Transfer: While sending these files somewhere else, any interruption in the transfer process can damage them. Mostly, the transfer process faces troubles like connection issues that cause file damage.
• Device Issues: Your phone can have hardware issues, such as sudden shutdowns or battery failure, that can corrupt data recordings. When it becomes corrupted, the tracking app won’t be able to carry more data until you fix the FIT file.
• Software Glitches: Bugs or errors in the device's firmware or associated applications can corrupt FIT files. Besides, incompatible software that does not support the file format can also cause the issue.
• Storage Issues: When the system does not have enough space to save the files, a part of the data gets lost. In addition to limited storage, a corrupted disk drive can damage the fitness files and other data on it.
• File System Errors: Problems with the device’s file system can lead to damaged FIT files and may even alter them permanently. Usually, these system errors occur due to bad sectors on the disk or malware attacks.
