Is there a name for this ab exercise!?

[kak39]

Trainer showed me this ab exercise I've been using for a bit, but have no clue what the name of it is...Here is my best description.

1.) Lay on back with legs/arms extended and flat on ground
2.) Lift your right arm/torso and left leg at the same time off the ground
3.) Make sort of a V shape w/ your torso and leg up in the air, touch your elbow to your knee
4.) Repeat w/ opposite combo (left arm/torso and right leg)
