Can 30 mins a day of eliptical or stationary bike harm your LBM? I'm not so concerned with hurting gains, as I'm not bulking atm, but I'm concerned about losing LBM that I have gained... My diet is not super conservative when it comes to calories... I feel I am taking care of my body nutritionally... but I just want to make sure that doing 30 mins of cardio won't be putting my body into a catabolic state...
