How can I effectively incorporate pull up knee raises into my workout routine to target my core muscles?

To effectively incorporate pull up knee raises into your workout routine to target your core muscles, start by hanging from a pull-up bar with your arms shoulder-width apart. Then, engage your core muscles and lift your knees towards your chest while keeping your back straight. Lower your legs back down slowly and repeat for a set number of repetitions. This exercise helps strengthen your abdominal muscles and improve core stability.
