3. Barbell Abs Exercises – Barbell Russian Twist
Stick one end of the barbell to the corner of a wall (over a towel for more stability) and load the other end. Standing with your legs hip-width apart, bring the loaded end in front of you with your arms extended.
Lower the bar to one side whilst rotating your hips and shoulders in the direction of the bar. Then bring it back up and repeat in the other direction. Make sure to keep your arms extended throughout the movement.
Starting with lighter weights that are gentle on the spine or no weight at all is a good idea. Only up the weight once you feel you’ve progressed.
