LA Fitness, an operator of 43 clubs in the state of Arizona, is launching a large-scale remodeling effort of 21 metropolitan Phoenix and five Southern Arizona locations. With the remodeling effort, a cutting-edge, high-intensity interval training workout, HIIT by LAF, is launched in the second studio in the nation at 3301 E. Bell Road (33rd St and Bell Rd).

Part of a national undertaking, the clubs’ refurbishment ranges from the modernization of equipment and specialized flooring to the introduction of a new color palette and refreshed studios and child-care areas. LA Fitness’ $13.6 million renovation investment in its Arizona clubs is complemented by the recent introduction of HIIT by LAF at the national fitness leader’s E. Bell Road location in Phoenix.

“For nearly 35 years, LA Fitness has been a true national trailblazer in the fitness club industry, so it’s fitting that we’re leading the charge in redefining fitness for today’s active and busy lifestyles,” said Dion Gentile, Regional VP of Sales and Marketing at LA Fitness. “As a fitness-conscious community, it only makes sense that some of our Arizona locations are set to be among the first in the nation to debut our new look and introduce our newest fitness program, HIIT by LAF.”

High-intensity interval training was recently endorsed by the U.S. Department of Health and Human Services (HHS) as a highly beneficial form of exercise. Designed for every level of fitness and goal type, HIIT by LAF is a high-tech, high-energy workout led by certified fitness coaches. With each workout lasting 50 minutes, members take part in a variety of functional exercises, core training, cardio interval training and strength training.

Wearing optional heart rate monitors, participants are led through five heart rate training zones, with each zone representing variations in levels of intensity that may result in participants burning up to 1,000 calories per workout including calories that may burn even after the workout ends (results may vary). After analyzing several studies, HHS determined that HIIT “can effectively improve cardiorespiratory fitness (increase VO2 max) in adults with varied body weight and health status” and can also help with insulin levels, blood pressure, and body composition.

“HIIT by LAF brings members an exciting and unique experience that combines cardio, muscle conditioning, strength training and physical endurance in a fun setting for anyone looking to take their fitness goals to the next level,” said Barbie Sparks, Regional Coordinator of Aerobics for the Arizona Region at LA Fitness.

Unlike most other traditional high-intensity interval training programs, HIIT by LAF offers a different workout every day, using cutting-edge equipment in a state-of-the-art studio, packed with modern interactive technology that provides participants guaranteed real-time feedback and motivating music that helps get the adrenaline going. People of all fitness levels are challenged, as the knowledgeable and passionate motivating coaches deliver an inspiring, fun and effective fitness experience in less than one hour.

“In a time-strapped world, HIIT by LAF gives everyone the chance to reach their fitness goals, and our coaches are determined to make sure of this,” said Sparks. “Whether it’s a mom looking to recharge, an athlete fine-tuning a workout in preparation for the next competition, or an executive seeking an efficient, 360-degree workout – HIIT by LAF will offer a little something for everyone.”

Workout schedules are unique to each HIIT by LAF location, and in order to participate in HIIT by LAF, an individual must first be an LA Fitness member. A separate membership agreement and fees are required to access this specialized workout. For more information and for workout times, visit or @hiitbylaf on Instagram.
