Smoothie too thick?

Hey everyone. I tried making a smoothie for the first time but it was far too thick. I used a cup of huel, 1 banana, 1 tablespoon of PB2, a cup of ice, and half a cup of yogurt.

Any suggestions on how to make it smoother and more like a smoothie? Should I use more ice? Switch out the yogurt for milk?

Any suggestions would be great.

Did you put any liquid in it? I would put at least 1 cup of water with all that, maybe even 2 cups.
