<human>:  What exercises can I do to strengthen my core muscles?
<bot>: The plank is a great exercise for strengthening your core muscles. It requires you to hold your body in a straight line for an extended period of time. 2 Other core exercises include bridges, Russian twists, bicycles, and side planks. 3 You can also do exercises such as squats and lunges to engage your core and build abdominal strength. 4 To mix things up, try yoga and Pilates, as they both focus on core strength and stability.
