I can entertain the idea that one's ability to gain LBM is hampered by cardio, but I'm a convert to the idea that one can gain LBM and lose BF simultaneously. Before this forum , I was doing either/or.
My weight hasn't changed more than a few pounds either way over the last few months - but my BF/ratio has greatly improved. It can only mean that I'm gaining LBM while losing BF - right?
