CrossFit workouts are among the most popular ways to get a sweat on, and for good reason—they’re great for building strength and endurance simultaneously. You don’t have to be a member of a CrossFit box to try them either. Many sessions are fairly short and require widely available kit so you can try them in a commercial gym.
This 15-minute workout from Sósie Cox, a personal trainer at newly opened functional fitness site Gymnasium Brixton in London, will put your strength and fitness to the test using just one dumbbell.
