There are many ways to track and measure physical activity.

1. Pedometers. Pedometers, which are tiny devices worn around the waist, count how many steps you take throughout the day. The devices are fairly inexpensive and offer a quick way to keep track of your daily activity.
2. Accelerometers: These small, wearable devices measure motion in three dimensions. These devices can give more information on physical activity including intensity and duration.
3. GPS Devices: GPS devices are used for tracking distance and speed during physical activities, such as running or cycling. The GPS devices can provide useful information on the routes taken by athletes.
4. Heart rate monitors measure the beats per minutes and can therefore be used as a tool to monitor the intensity of exercise. This data can help determine whether the intensity of physical activity falls into the range of moderate to vigorous.
5. Self-reporting questionnaires. Self-reporting questionnaires can be a cost-effective and simple way to track physical activity. The participants are asked to provide a summary of their level of physical activity over a certain period, typically the week before or last month.
6. Apps for mobile devices: Many apps can track activity. They use sensors on smartphones to measure distance, step count, and other measurements of physical activity. These apps can provide motivation and reminders to get moving.

Cost and simplicity of use are important factors to consider when choosing a technique.
