Here I used Hero Forge to design the skinny rabbit and his coach. The rabbit is not particularly happy with the beginning of his training.

Story
Joran explained to his family that he was moving in with a new girlfriend. The boys congratulated him on his new girlfriend and wanted to know what kind of rabbit she was. When he honestly said it was a female elephant, his parents were worried. They said that he was careless, that he could be squeezed to death, and other things that could make living together a risk. But Joran stuck to his decision because the female elephant can give him what he so longed for. But he didn't give any details. Joran took only the bare essentials and moved in with Kymopoleia. Kymopoleia had provided him with a room, a large room. She announced that he should show up tomorrow morning wearing only athletic shorts. Joran later went to bed and was determined to fully devote himself to Kim's training program. He managed to wake up early and Kim was already waiting for him. Joran was a little embarrassed that this huge female elephant saw his scrawny body. After a small but protein-packed meal, Kim insisted he take her for a long run to warm up. After the long run, Joran was a little exhausted, but determined to lift the weights. In his cockiness, he wanted to lift a very heavy dumbbell, but that didn't work. Kim told him that he should first lift with appropriate weights, otherwise he would seriously injure himself. To Joran's chagrin, he first had to lift with dumbbells without weights. But Joran trusted Kim and his patience.
