The Leg Raise is a popular exercise that primarily targets the abdominal muscles, particularly the lower abs. To perform this exercise, lie flat on your back with your legs extended. Slowly lift your legs towards the ceiling while keeping them straight, then lower them back down without touching the ground. This movement engages the core and helps improve strength and stability. Leg raises can be modified for different fitness levels. Beginners may bend their knees while lifting, while advanced practitioners can add weights or perform the exercise on a pull-up bar for increased difficulty. Regular practice can enhance core strength and overall fitness.
