I do not currently have the Sims Fitness Stuff Pack, but there is enough space in this design to accomodate for this option. I have designed it to have everything that is allowed in a Gym Model, meeting minimum requirements, with high standards. There is a downstairs yoga room, meditation chamber, sauna, swimming pool, bathrooms, gym lockers, showers and toilets, First Floor, is the Reception and Gym Equipment, including, boxing post, treadmills, weightlifting machine, and dancefloor. #gym #reno
