- Begin in an elbow plank position with a small, folded towel or paper plate under each elbow. Keep your elbows directly under your shoulders, back flat (neutral spine) and core tight!
- Slide your right elbow forward until your arm is nearly fully extended. With control, bring the right elbow back to center.
- Repeat on the left side. This completes one rep. Start with 10 reps and work your way up to 20!
- If you need to modify, you can drop to your knees (while keeping your back straight and core tight); you'll still work the core and triceps!
You will be shocked by how intense this exercise is on both your abs and arms. But don't throw in the towel (see what I did there?).
