These Are the 19 Best Ab-Strengthening Exercises Using Weights That You Can Do at Home

In this variation, the abs work extra hard to maintain stability as you pull the dumbbell away from your center.

• 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.
• With your left arm remaining 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.
• Switch sides, and do the same number of reps on each side.
