The weird thing for Bruce was that he wasn’t sick of the exercise. Considering his formerly out of shape body, he never expected to be actually enjoy exercising, but in Natasha’s body it was a breeze. It was the fact that she wouldn’t ever stop telling him what to do. For instance, she insisted he use a certain size weight, even if he wanted to try out one that was heavier. He knew her body could handle it. On top of that, he had to watch her in his own body continue to progress, going from lighter to heavier weights, getting more toned and fit. Despite the fact that he was probably in the best shape in his life, it made him feel like a weakling. Bruce always had feelings of inferiority; it was part of what had caused his overeating in his previous body. Natasha’s workout demands had helped at first. They had given him a confidence he certainly wasn’t used to, but after several years, his natural emotions dragged him down. He felt like he could do more, that her demands were belittling of him, and he was ready to prove to himself that he no longer needed her.
