Lauren Tanner is the only daughter of the Rock's founder, Steve Tanner. While her mother (unnamed) is absent from the scene after abandoning her family due to her drug problems. A situation that has impacted young Lauren in ways that are rather obvious. Such as: her need to have her fathers full and undivided attention on her at all times and her now growing obsession with her supposed best friend's boyfriend (Carter).

A classic spoiled rich girl, Lauren tends to get everything she wants when she wants it. And is none to shy about showing her displeasure when she doesn't approve of something. Like her father's newfound relationship with his secretary/personal assistant, Summer. And the arrival of The Rock's newest potential star, Emily Kmetko, a girl that Lauren views as subpar in talent to her own. While her own talent is unquestioned by Coach Beoff he does wonder if she can channel it in a way that will be produce gold.

Becca Keeler is the youngest daughter of Mark and Kim Keeler and the younger sister of Payson Keeler. A fellow gymnast like her sister, she's currently one level below her sister and scored well at the Rock's invitational. Was really devastated when the family chose to leave their native Minnesota for Boulder (Colorado) to let Payson train at Rocky Mountain Gymnastics. Though she's since settled in to her new surroundings she still longs to return.

Summer (no last name) is the girl with the sorted past who has gone on to be a good "christian" girl and is intent on spreading the message to her new friends and potentially future family. Though dressing to kill and driving a high end car doesn't seem to be against her "faith". She is currently working as the personal assistant to Steve Tanner and the two have recently began dating and are planning to be married.

Chloe Kmetko is Emily's flamboyant mother. With a flair for the fabulous, Chloe is more friend than mother to Emily and her brother, Brian. But even though she may not be your stereotypical mother, Chloe will do anything for her children. Displayed by her move of Emily and Brian to Boulder, Colorado, for the expressed purpose of giving Emily the chance to train at Rocky Mountain Gymnastics (The Rock) and possibly achieve her dreams of Olympic gold.
