Feel Sore After This 15-Minute Arms and Abs Workout — Only Dumbbells Needed

• Start in a plank position with your legs wider than hip distance; the wider stance makes you more stable. Hold onto your dumbbells, keeping your wrist locked to protect the joint.
• With your core tight and your glutes engaged, exhale, stabilizing your torso as you lift your left elbow to row; feel your left shoulder blade sliding toward your spine as you bend your elbow up toward the ceiling.
• Keeping your neck long and energized, return the weight to the ground, and repeat the movement on your right side.
• Do a total of 10 reps (five reps per arm).
