#6 – Russian Twist
A great exercise for the oblique muscles of your core as it involves a twisting motion of the abdomen.
Sit on the floor with knees bent like in the ‘sit-up’ position. The feet should be together and slightly off the ground to make it harder, the torso at a 45 degree angle to the ground and the arms kept together and extended out in front of the body. Twist your torso to the right until the arms are parallel with the floor while breathing out, pause, and then move back to the starting position while breathing out. Repeat on the left-hand side.
You can hold a weight plate or medicine ball out in front of you to make this exercise more challenging.
