"But it's good for keeping my arms defined, but not too bulgy." Lola was very much looking to look good. Being the strongest, or the fastest, or any of that wasn't the point. Plus she's having fun, so she doesn't mind Keith is winning. "This is better though, much nicer view."

Keith being in the lead means Lola can check him out as she climbs. Which if he was thinking about it might be a worthwhile reason to let her lead a little while.
