Katrina Hodgson and Karena Dawn are best friends, roommates, and the beautiful brains and bodies behind one of the hottest and fastest growing fitness companies, Tone It Up. In the premiere episode, the girls plan an important marketing event for their company, but the high-end, avant-garde approach may bring down this critical affair before it even gets off the ground.

When Katrina and Karena decide to throw a celebrity-studded event for their new product, the girls get distracted by "Cyber Monday." With procrastination the monkey on their backs, they may lose prep time for this important occasion that will either make or break them.

The heat is on and Katrina and Karena prepare to shoot their second "Beach Babe" exercise DVD in Maui. During this very hectic time, Katrina's fiancée Brian makes the mistake of asking about the future of their living situation, which irritates Karena. With the pressure of preparing for the shoot and the jeopardy of her future living situation, Katrina aggravates a chronic neck injury that puts the shoot in serious danger and could cost the girls $100,000.
