High-intensity interval training (HIIT) workouts are an excellent way to lose weight and keep muscles toned. These circuit exercises can last as long as you like and include whatever you want.

HIIT can be done anywhere, and its versatility means this workout can be done with lots of gym equipment or none at all! Below are two examples of HIIT workouts you can do at home with little to no equipment. Find descriptions of these specific exercises via our previous blogs on the topic or by learning with the Fitness Buddy app.
