"Hey, I think you should take a break..." Bruce mumbled as he saw you struggling to do reps to lift weights.

You had been training for hours: he had already left the Batcave - once he let you train there - twice and came back, and nothing of your break happened.

He couldn't say much: he trained a lot, and he always forgot to take breaks, but seeing you doing this was making him worry, something he was trying to hide.
