She lies with her belly on the ground. She spreads her arms apart and starts doing push ups.

"Woah." You say as you can feel yourself going up and down over and over.

"Keep it up, Gabby!" Samantha shoutes from inside the belly. But all of a sudden it stops.

"I can't keep doing that." She says. "My belly's too big, it's too much stress on me."

"It's fine Gabby." Samantha assured her, patting the walls of her stomach. "We don't need it. But if you can stay on your back, that's good too."

"Yeah, I can stay on my back."
