Flexion Leg Sit up (straight arm)

The Flexion Leg Sit up (straight arm) is a challenging exercise that targets several muscle groups, including your abdominal muscles, hip flexors, and thighs. It is an effective movement for strengthening your core and improving overall stability. To perform this exercise, begin by lying flat on your back with your legs extended straight out in front of you. Extend your arms overhead so that they are in line with your ears, creating a straight line from your fingertips to your toes. As you engage your core muscles, simultaneously lift your upper body and your legs off the ground, aiming to touch your toes with your hands. Maintain a controlled and smooth motion throughout the movement, focusing on your core strength to generate the power needed to lift your body. It is essential to keep your back straight and avoid rounding your lower back during the exercise to prevent injury. Remember to exhale as you lift your body and inhale as you lower yourself back down to the starting position. Add the Flexion Leg Sit up (straight arm) to your workout routine to challenge and strengthen your core muscles while improving overall body stability. Combine this exercise with other abdominal exercises and a balanced nutrition plan for optimal results.
