Ribbing in the Round?

Hi, I am finishing the leg of a pair of pants I have knit in the round (three double pointed needles). The pattern says to do a one by one rib, but when I try it I end up with what looks like doubled up stitches, which are also very tight. Is there a special technique for doing ribbing in the round?? Is there a common pit that I’m falling into?


You need an even number of sts and just k1, p1 around and around.
