5. Leg Raises
Leg raises can help strengthen the lower part of the core, but they should be done carefully. Lie on your back with your legs straight or slightly bent. Slowly lift your legs upward, then lower them back down without letting your lower back strain. If your back lifts too much, bend your knees or make the movement smaller.

This exercise can feel challenging, so there is no need to do many repetitions at first. Focus on slow control and breathing. You can also place your hands beside your hips for support. If it causes back discomfort, choose a gentler exercise like dead bug instead.
