This video tutorial guides viewers through a 60-second core routine designed to strengthen the abdominals. It includes four exercises: circles, center side center, bicycles, and dead bugs, each targeting different parts of the core. The tutorial emphasizes proper form and the importance of keeping the shoulder blades off the floor and the lower back flush to the ground. The routine is suitable for warming up before dance classes or competitions to enhance core strength and stability.

Explain how to perform the 'dead bugs' exercise correctly.
