I'm looking to learn about the Russian Twist exercise on The Gym Group's website. Can you find its exercise guide? Once there, please tell me the primary muscle groups it targets and outline the first two steps for performing the exercise correctly, as described on the page.
Navigate to 'thegymgroup.com' Locate and click on the 'Exercise Hub' or similar section for exercise guides. Find and click on the 'Abs & Core exercises' category. Scroll down to find and click on the 'How to do a Russian Twist' link. Identify the primary muscle groups targeted by the Russian Twist. Extract the first two key steps for performing the Russian Twist correctly from the guide.
Successfully navigate to the 'How to Do a Russian Twist' exercise guide page. State the primary muscle groups targeted by the Russian Twist as 'obliques and core'. List the first two distinct steps for performing the Russian Twist as: '1. Sit on the floor or mat with your knees bent and feet flat on the ground. Your lower body should be in a similar position to the classic sit-up or crunch position.' and '2. Sitting up, angle your upper body 45 degrees backward. Keep your back neutral and your shoulders in their natural position in order to maintain good posture and avoid strain.'
