You and your spouse or a friend (or one of your own kids) will take on daily partner workouts and healthy eating for 30 days. Just having that person around is going to give you the motivation to complete the entire program — and help you build stronger bonds along the way!

Tony Horton P90

What: 30 days of total-body workouts (all 35 minutes or less) that feel more like play and less like work! Who: Anyone at any fitness level (ages 8 and up) can do Double Time. Why Work Out With a Partner? Studies show that you’re more likely to succeed with a fitness routine when you work out with another person. You’ll encourage each other to show up. You’ll cheer each other on.

And they’ll make it way more fun, too! Using the Beachbody Buddy Ball, you and your Double Time partner will communicate and rely on each other to complete every single move. You’ll be so focused on laughing and working together that you won’t be looking at the clock — so imagine how much easier it will be for you to stick with your new healthier habits!
