Just Fitness 4 U Jacksonville has equipped its three locations with myriad machines, amenities, and classes. Its group fitness classes shake up fitness routines as instructors model Zumba's Latin-inspired dance moves to the thudding base of global party hits and Hot Hula classes get hips swiveling to island rhythms.

The Baymeadows location's cardio equipment is equipped with cooling fans and personal screens that show high-definition cable TV. Guests also can refresh at the smoothie bar, pump up their muscles on Star Trac and FreeMotion strength-training equipment, and furiously peddle while admiring a vibrant graffiti-style mural by a local artist in the cycling room. Plush leather couches and a waterfall welcome members to the Mandarin location, whereas the Southside location summons guests to watch movies and chase after screen villains atop Cybex equipment.

All three locations entertain exercisers with either Cardio Theater equipment or a cardio cinema. The staff screens action-packed flicks such as Mission: Impossible – Ghost Protocol, Man on Fire, and Avatar and promises not to weep openly during the emotional scenes.
