Plank and Straight-Arm Kickback
Work your arms and abs together with this plank variation.
- Start in a plank position holding a dumbbell in each hand. Open your feet wider than hip width for a stronger base of support.
- Lift your left arm behind you as high as you can. Bring the left arm back into plank to complete one rep.
- Do 10 to 15 reps with each arm.
Use two to five kilo weights.
