I guess it could be your obliques because depending on what type of cardio you are doing your internal obliques are responsible for twisting your upper body. I dunno... never experience it and I don't ever do cardio.
Maybe because I do my abs everyday I'm not allowing time for repair, not sure but I might just drop my cardio.
I'm on my 2nd week of test and deca cycle, so I was told to do around 20 mins cardio with my workouts daily.

Thanks mate for the help.
