Frequently Asked Questions

What is HIIT by LAF?

HIIT by LAF is a workout that is designed for almost every level of fitness, age, and goal type. These high-tech and high-energy workouts are led by motivating, certified fitness coaches who set the pace and vibe of the room. Each workout is 50-minutes long and comprised of 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).

What is MYZONE?

MYZONE is a innovative heart rate-based system that uses wireless and cloud technology to accurately and conveniently monitor physical activity. It monitors heart rate, calories and time exercising that converts into MYZONE Effort Points (MEPs), with a focus on rewarding effort rather than fitness.

Heart rate training zones are a range of values expressed as percentages of maximum heart rate (HR max). The HIIT by LAF workout incorporates 5 heart rate training zones. The MYZONE heart rate monitor is available for purchase at an additional cost. Each zone is identified by zone color, heart rate percentage range, zone description, and the target amount of time that should be maintained in each zone to achieve the greatest benefits of a HIIT workout. Utilizing these zones in relation to the exercise benefits of each one aids in the development of the best programming to maximize endurance, calorie burn, and fat loss.

What is a MEP?

MYZONE Effort Points (MEPs) are earned based on the effort exerted by the participant. Time spent in each Heart Rate Zone earns different numbers of MEPS:

Grey = 50-59% – Earns 1 MEP/minute
Blue = 60-69% – Earns 2 MEPS/minute
Green = 70-79% – Earns 3 MEPs/minute
Yellow = 80-89% – Earns 4 MEPs/minute
Red = 90-100% – Earns 4 MEPs/minute

What HIIT by LAF workouts do you offer?

The combination of our 3 workout formats is the secret to lasting results. The idea is to consistently work in Strength, Endurance and Define workouts to cover all bases in training for optimal results.

Strength: Build strength and lean muscle while burning calories in this intense HR targeted workout. A variety of strength training equipment is used to help you achieve a stronger body. Bikes, rowers, and treadmills challenge you to reach your optimal fitness performance. More weight with fewer reps maximize your power and muscular strength.

Endurance: Endurance workouts are designed with the goal of increasing overall cardiovascular and muscular conditioning while achieving a lean and healthy physique. High repetitions with short-burst of core-challenging exercises are programmed to increase your fitness. A mix of intensities on the treadmill, rowers, and bikes help increase muscular and aerobic endurance to get the ultimate burn.

Define:  The perfect combination of strength and endurance training to sculpt a toned, fit body. Periods of high, medium and low intensity intervals with rest periods aid in helping to improve athletic performance. Dynamic exercises and drills build muscle and increase power. DEFINE will take your performance to the next level.
