Member Quotes

  • I've never had a gym provide workouts that are as intense but DOABLE for so many different fitness levels. I've crossfitted, I've trained at LA fitness, I've used multiple online programs, and I've never gotten results like I've gotten from Peak Zone. I'm in the best shape on my life and I fully attribute that to PZ. I love that all I have to do is walk in and the workout is already planned. I know I'll be there for 50 minutes and have an incredible workout. Takes a lot of stress out of working out!

Peak Zone Fitness™ Tour

Peak Zone Fitness™ is a One-on-One Personal Training Program which is done in a Group Setting

Go to Step 2 to learn how we track each individual’s program


Workout Monitor (click for larger image)

Each person’s numbers are personalized based off of their fitness level and goals.

As you work out, your heart rate, calories burned, and MEPS (effort points) are monitored and displayed on our wall monitor for you and your trainer.

The goal is to work out at your Peak Zone (See Step 3 for more details) which is personalized for your own fitness level and goals.

In the photo above, you will see the board showing the current status of the members working out.

Your Peak Zone is customized using science’s best medical advances (VO2 max test) for fitness. Using the VO2 test and many other variables your peak zone is generated at an 80% percentile mark using the MyZone software.

One person’s 80% effort may be walking on the treadmill, and another person’s 80% might be running at 8mph.

Each person, therefore, gets the exact workout they need for their specific goals, such as weight loss, toning, health, bulking, endurance, training, etc..

Each member’s fitness level is continually assessed and the effort level is adjusted.

In the photo above, you can see that most of the members are right at the 80% with a couple of exceptions and so the trainers are busy slowing them down or stepping them up.

Watch this video to learn more about VO2 Max testing.

Basal Metabolic Testing and Nutrition

After we perfect your workouts using the VO2 test, we will perfect your nutrition using a Basil Metabolic Test.

reevue_sample_reportThrough Basal Metabolic testing you can:

  • learn how to accelerate your metabolism
  • learn how many calories you burn at rest
  • learn how many calories you burn when active
  • learn how many calories you burn while exercising
  • learn how many calories you need to maintain, lose, or gain weight
  • This test is free with membership and can cost over $150 elsewhere, if you can find it.

Your Nutrition Perfected

Once we have your testing results and know your current fitness level, we’ll work with you to develop your own nutrition program, individualized to you and what you are willing to commit to.

You will receive a 30 page book that will teach you how to be a nutrition and supplement manipulator as well as a complete personalized grocery list of foods.
