Les Mills Gets HIIT: Group Fitness Experts Launch 30-Minute High Intensity Workouts

Those Ready to Work Hard in a Small Team Environment Need Only Apply

SAN FRANCISCO, CA--(Marketwire - Feb 5, 2013) - High-intensity interval training (HIIT) is all the rage and Les Mills, creator of some of the world's most popular group fitness programs, has amplified the experience, mixing music and choreography in a team training environment with its new workouts from the LES MILLS GRIT™ Series.

Backed by scientific research (see below) and delivered in 30-minute high intensity blasts, the LES MILLS GRIT™ Series workouts are demanding, but they're over quickly, with each session flipping between short bursts of high intensity and recovery periods -- the best way to increase fitness, tone muscle and lose fat.

Les Mills has also crafted the workouts so that they can be delivered to various sized groups in various settings. In this way LES MILLS GRIT™ Series is ideal for getting a premium, personal training-style workout without the expensive price tag.

It also goes hand-in-hand with existing training. It can be swapped into a current workout regime instead of traditional cardio and it will intensify the results already being achieved from any group fitness and muscle conditioning programs.

The three unique 30-minute workouts being launched around the world are:

  • LES MILLS GRIT™ Strength blasts all major muscle groups using barbells, plates and the bench. Your metabolism goes into overdrive to burn fat for hours after the workout.
  • LES MILLS GRIT™ Plyo creates a lean, powerful, athletic body using the principles of plyometrics (power agility training). You'll increase your speed, strength and endurance by transforming up to 40% more muscle fiber.
  • LES MILLS GRIT™ Cardio burns fat and rapidly improves your athletic capability. No equipment is needed for this explosive, high-impact body-weight routine.

The science
The high-intensity interval training of LES MILLS GRIT™ Series is scientifically proven to improve fitness faster than conventional training methods1. And this is no empty claim, as recent research by Dr. Jinger Gottschall at Penn State University proves that LES MILLS GRIT™ Series gets real results.

Over six weeks, two groups consisting of 42 fit adult exercisers each engaged in five hours of quality, professionally-designed exercise per week. The point of difference was that one group substituted one hour of cardio for two 30-minute LES MILLS GRIT™ Series workouts.

After six weeks, increases in cardiovascular fitness and strength and decreases in triglycerides, body fat and waist circumference were recorded by all. But those who braved the LES MILLS GRIT™ Series workouts enjoyed the benefits at more than twice the rate across all measures.
