I remembered te other day this fic but I can't find it now, and I really want to read it again.
I am afraid that my google-fu habilities are really low, because I remember a lot of details.
As I said in the title it was a Jensen/Misha story. It started with Misha and I think Rob in Mishas store about yoga or something like that and he was trying to lift some boxes and failing pretty bad so Rob? told hi to join a gym.
It was Jensen's and Jared's gym and I thing Gen was the receptionist or something.
He joins the Gym and Jared starts to train him but then Jensen trains him. Someone tolds MIsha Jensen's name but he hears it wrong, and then he can't find Jensen because he understood Jason. Misha is bad at weights but good at running and there is sex in the office and stuff.

There are a lot of details but I can't find it. I read it in AO3.
Some help would be awesome.
Thanks in advance.
