A 'Friendly' bet at the gym

Sally and her best friend Rachel were both total fitness girls. They signed up for the gym together, prepped meals together, and worked together to keep each other as fit and athletic as they each wanted. They also had a playful, though often out of hand rivalry. They pushed each other, but there was some real tension that came out occasionally.

They were on machines next to each other, and people at the gym were gathered to watch. They were currently on their 25th rep at 350 pounds, and both girl's were shaking with exertion. Unfortunately Sally caved first. She simply could not complete her 26th rep.
