This exercise feels like a great stretch combined with a plank. Keep your abs engaged and your body in a straight line for best results.
- Start in plank position (hands under shoulders, legs extended, back flat, toes tucked under).
- Slowly lift your left arm and right leg off floor at the same time. Hold for 3 to 5 seconds; lower.
- Lift your right arm and left leg; hold for 3 to 5 seconds and lower to complete one rep.
- Continue alternating sides for desired number of reps, holding plank position throughout.
