Can I use the apps at home or at the gym?

You can use the app both at home and at the gym while using the required equipment! The workout program you select in the app will mention what equipment is necessary for the workout. If you tap on the image of your desired workout day, it should open a list of all the exercises that are associated with that specific workout. Each exercise video should show you what type of equipment is needed to perform the exercise correctly. You can also advance to see upcoming workout days by swiping from right to left on your main workout screen.
