Circuit Three: V-Sit With Single Arm Chest Fly
Reps: 10, each arm
- Begin sitting with your heels planted about two feet from your butt, holding the weights at chest level with a slight bend in your elbows. Lean back a few inches, pulling your abs toward your spine.
- Keeping the left arm still, open your right arm to the side, making sure the weight doesn't go beyond your shoulder.
- Bring your right arm back to center to complete one rep.
- Complete 10 reps with the right arm, then switch sides.
In this variation, the abs work extra to maintain stability as you pull the dumbbell away from your center.
