Leg circles are a dynamic exercise that targets the abdominal muscles while also engaging the hip flexors and improving flexibility in the lower body. To perform leg circles, lie flat on your back with your arms extended alongside your body or under your hips for support. Lift both legs off the ground and extend them straight up toward the ceiling. Keeping your core engaged and your lower back pressed into the floor, slowly lower one leg down toward the ground in a controlled motion, tracing a circle with your toes. Bring the leg back up to the starting position and repeat the movement in the opposite direction. Alternate between legs in a smooth and controlled manner, focusing on maintaining stability and control throughout the exercise. Leg circles can be performed with varying range of motion and speed to challenge different muscle groups and improve overall lower body strength and flexibility.
