The standing side crunch is a great way to work the abs from a standing position. To really focus on the abs, do this move in a slow, controlled way rather than using momentum, taking care not to round through the back. For more cardio, speed things up and do this move as fast as you can to get your heart rate up.
- Begin in a standing position, taking the right arm straight up in the air.
- Shift your weight to your left leg and slowly bring the knee up and out to the side.
- At the same time, bring the right elbow down towards right knee, squeezing the obliques.
- Take the arm up and the foot down and repeat for 1-3 sets on each side.
