Full upright plank pose vs. forearm plank pose. page

What is the main difference in the effect each has?
Which do you think is harder?
Is one better than the other?

i'm not sure if they really have too different effects on each other, but i think the one on your forearms is a lot harder. i can only hold that for a minute or two, but in the upright position, i can stay up there for a lot longer time.

In the PBF the progression is from the full upright plank to forearm. I can only hold the forearm for 1 minute, I got a ways to go!

I would say neither of those pictures are a "proper" plank. Yes, it should be on the forearms, but with your back and legs straight (not bent in the middle with your arse in the air)

First photo looks dead-on to me. Second one the butt is a bit high.

As for the difference between the two, people who lack shoulder and arm strength will find it harder to hold the plank on their hands, while those who lack core strength will likely find the elbow plank to be more challenging. As the angle of the body becomes closer to parallel with the ground, it becomes harder for the trunk muscles to stabilize and maintain form, though having the elbows bent takes a lot of pressure of the shoulders and arms.

So the forearm one isolates the abs better, and should be chosen if ab insanity is desired?
