10 Simple Moves to Get a Tiny Waist and a Flat Stomach

3. Torso twist stretch

The torso twist stretch works on your transverse abdominal muscle and obliques.

• Start by sitting on the floor.
• Stretch out the left leg and bend the right leg.
• Support yourself with your right hand behind you, turn the upper body to the right and bring the left arm over the bent knee.
• Do not overdo the rotation, it should be a stretch, not a load.
• Wait about 10 seconds and return to the starting position.
• Repeat the exercise on the other side.
• Do 5 repetitions.
