As the weather gets cooler, your workout might change. There's a new app, plus several others, to help you switch your exercise routine from outdoors to indoors.
Runners and hikers seeking new paths for fall weather can try an app like Runkeeper for iPhone or Android. The app keeps track of personal pace, distance and time, and lets you set goals.
Those looking for a new routine indoors can look to an app like Workout Trainer for Android. It's got a variety of videos and instructions for workouts and lets users map out plans and track progress online.
The free Simply Yoga app acts as a personal yoga instructor - guiding users through yoga routines of varying lengths and featuring videos of certified instructors teaching and demonstrating new poses.
Keep tabs on your heart rate with an app like the Instant Heart Rate Monitor, which tracks vital signs when you place a fingertip on the iPhone's camera.
