Staying in shape over the holidays isn't as challenging as you might think, especially if you focus on quality over quantity when it comes to your workouts. This high-intensity interval session is the second routine in our Black Friday Fitness program, and it was designed to help you work up a major sweat—without stressing out your already packed schedule. You won't need a single piece of equipment or a lot of space for this routine, so you can do it in your hotel room or wherever you may end up during this busy holiday season.
