At one point, Natasha stepped away to take a phone call. Bruce saw this as his chance to take some initiative. He jumped onto the heavier weights, but he soon found that while Natasha’s body was fit, it certainly wasn’t strong enough to take on that much. He found himself struggling to lift the massive weights. When Natasha returned, she laughed upon seeing Bruce’s attempt. She told him that she might be able to amp up his program a little bit, but with her former frame, there’d be no way he’d ever be able to lift that much. Bruce sighed. Despite being in the best shape of his life, he felt weak again...just like he used to feel in his former body.
