Working out during the ads can be surprisingly effective:
It turns out commercial breaks can vary in length and frequency depending on the program, but the average half-hour TV show contains about 8 minutes of advertisements, divided into two or three breaks. So we’ve got three bodyweight circuits for you: Perform each exercise for 45 seconds and move straight on to the next exercise without resting. Alternatively, each exercise can be performed for the length of one commercial (restart the circuit if there are more than three).
Here’s the chart of the workouts you need to do in each of the three commercial breaks in a half-hour show. If you don’t know any of them, hit the link at the bottom to get details of the exercises from Greatist.
