Stubborn teenager don't want to go inside

No matter what I try it is currently a struggle everytime we need to go back inside from a walk. I live in an apartment so he can't stay outside, and I make sure we have proper "outside time" (walking or just hanging out). He will lie down and refuse to come with me inside. Sometimes I can get him inside without struggle, but only if I run so it becomes a game to chase me (my neighbours must think I'm crazy).

He has done this before, but then not done it for months. I am loooooosing it but can't yell at him (who want to go to someone who yells?). Just needed to vent. This sucks right now.
