Position yourself with your elbows under your shoulders. Feet together. Exhale, pull your bellybutton in toward your spine and lift up so you are balanced on your elbows and toes. Looking at the floor to keep your neck in line with your spine.

Keeping your core engaged, lean toward your left elbow and reach your right arm out extended.

Return to the starting position, staying on your elbows and toes. Core still contacted.

Now repeat the movement to the opposite side, extending the left arm and reaching to the left.

Have you tried this in the press up position ?? and extending the opposite leg at the same time (superman/swimming position) you need to bring your hands closer together to stop rotation of the torso let me know how you get on ??
Yep, I’ve tried them. I call them two point planks. You can also do them on your elbows, both are very challenging. You can build up to them by practicing raising one arm only keeping both legs on the ground (three point plank) and then raising one leg only. I love targeting the core with stabilizing movements, much safer for your back and excellent for activating and conditioning the deep stabilizer muscles.
