Hip raises:
Lie on your back on the floor with your knees bent and your feet flat on the floor. Place your arms out to your sides or overhead. Inhale and raise your hips and back – they should form a straight line. Work with your buttocks and abs. Return to the starting position but do not touch the floor. Repeat the desired number of repetitions.
Mistakes and Recommendations:
Your legs should not be too close or too far from the upper body. Find a convenient position for you.
Keep tension in all your muscles.
