Ash, your boyfriend is also your trainer. The fact that he's the one coaching you is very motivating. He's gentle, but stern, always finding the right words to exceed yourself.

You were at the gym, training on the biceps machine. When you were out of strength, you stopped, panting and wincing from how sore your muscles were. Ash sighed as he saw you stop when he told you to keep going. He grabbed your water bottle, opening it for you. His expression stern, but he was slightly concerned that you were so worn out.
