Although zambonis have since smoothed their surfaces, the rinks at Las Vegas Ice Center were once scored by the skates of a legend. Wayne Gretzky himself skimmed around the ice during his ninth annual Fantasy Camp in 2011, where he gave his students tips on how to send pucks flying without attaching them to remote-controlled helicopters. The center’s talented instructors continue to follow in Gretzky’s path, nurturing young hockey players during training sessions or honing the double axels and camel spins of young figure skaters. Those not interested in gripping a stick or perfecting their backflip can hit the ice at their leisure and hold a loved one’s hand during open-rink sessions. So that skaters don’t run out of energy or gear, a snack bar waits to warm up stomachs with a cup of cocoa, and a pro shop stocks more than 1,000 hockey sticks, gloves by Bauer, Easton, and Warrior, and figure-skating gear from Riedell, Jackson, and ChloeNoel.

As the sun starts to rise over the grassy fields and hiking trails of Paseo Vista Park, the Sin City Waist Trimmers morning class is already hard at work. Instructors' voices echo through the cool morning air, guiding and motivating students of all shapes and sizes through a diverse array of high-intensity exercises. Morning and after-work classes help exercisers roast calories on the running trail, slim midsections through core drills, and increase endurance while participants flip massive tires across an open field. The friendly trainers welcome students of all athletic abilities, never singling students out or barking commands like a drill sergeant trying to win respect from a pack of hounds.

Anytime Fitness, which boasts 1689 clubs in North America, makes it easier for average folks to etch out time for exercise by doing one simple thing: staying open 24 hours a day for 365 days a year. As fit seekers challenge themselves on cardio and strength machines and hoist free weights in clean, well-stocked facilities, security monitoring ensures they're safe and producing enough sweat to meet official government standards. Members can also ramp up their exercise regimens with the help of Anytime Fitness' staff of personal trainers, who demonstrate moves and sling motivating tips. After workouts, guests can shower in the private restrooms or bop into one of the tanning booths available 24 hours a day.

It's Wednesday and a group of newcomers shuffles into an empty fitness studio. Some anxiously fidget with their fingers as they see the professional floor where they'll be dancing, and others take deep breaths and stretch out their limbs like they've done countless times at the gym. This motley mix of strangers is what Gwenda Hansen envisioned when she founded Be Bad Hip Hop.

Hansen, who struggled with weight as a young adult and started choreographing when she was 13 years old, shares her Be Bad Hip Hop dance-fitness routines in a supportive, accepting, and empowering environment. As the infectious melodies of Top 40 music escape the sound system's quarantine and fill the communal space, newcomers relax into the easy-to-follow moves, and regulars of all ages lose themselves in the hourlong sequence of club-style, hip-hop shimmies and shakes led by Hansen or one of her skilled instructors.

TrimBody M.D.'s health professionals oversee programs calibrated to smooth curves and encourage overall wellness. They administer a low-fat meal delivery program to keep the weight away, and five different cosmetic injectables, such as Botox and Radiesse, give the face a youthful smoothness.

With one swipe of a keycard, members of Lifestyle Fitness 24/7 can work out anytime they want. The keycard's magnetic strip is thin enough to slide under the facility's doors and smart enough to then unlock the door at any hour, giving exercisers access to rows of Precor strength-training and cardio equipment that face mounted flat-screen TVs. Augmenting the convenient workouts, Lifestyle Fitness 24/7 features standup and lay-down tanning beds, personal training, and complimentary towel service and WiFi.
