If he is lying, then "what" would he exactly be trying to cover up?
Hey, we're all just theorizing here. I have no idea. It's not like he was wrapped up with shady characters, right?

Hi Dave jacobs!
Why couldnt he just say he tore it in gym doing some exercise?
Maybe there are insurance reasons. Maybe all his bills are paid if he is hurt at home and none are paid if he hurt it at the gym. Who knows.
1-he doesnt want ppl to think he doesnt know how to properly execute the movement
Silly.
2-what would the negative be about telling truth?
Another thing we couldn't possibly know.
Look, he probably fell at home and hurt it. But for gossip & discussions' sake, when you have two people, you have two stories, and that was an awkward moment they had, describing how she found out..... well, it opens the door up to 'what ifs'. Branch was mixed up with Dave jacobs... hell, they were trianing partners. Doesn't mean a thing, or it could be something.
Bottom line is, it's his business, but to the casual listener, the story does make you smirk a bit and wonder what they're hiding
