Brandon has the impressive credentials and education to train like no other! He changes the way one looks at being ‘fit’, and focuses on improving strength for the long run. It’s about seeking quality of life and improving longevity through strengthening each area of the body. He is providing customized training for me and my husband, and we are so glad to be on this fitness journey with him!

I’ve been training with Brandon at the Strength Laboratory for approximately 2 months. Brandon’s knowledge, patience, and motivational skills are off the charts. He carefully explains each exercise, and the muscle group being affected, and watches to make sure I’m performing the exercise properly. I feel better, my strength and blood pressure have improved, and I look forward to each training session.

Questions

Before Your First Visit

What does a first visit look like?

Your first visit starts with a Longevity Analysis — our six-point assessment that shows exactly where you stand and becomes the basis of your personalized program. It takes twenty-five minutes and there is no charge.

Can I walk in, or do I need to book?

Everything here is by appointment, including your first visit.

How long are classes?

Forty-five minutes, with a maximum of eight members per session.

Can I still participate if I have an injury?

Usually, yes. We measure first and program around what your body can do. If you are still under a provider’s care, we ask that they clear you before you train with us.

I have never trained in my life.

Then you are exactly who this was built for. Your weight is set from what your body produces on the day, so a beginner and an experienced lifter can train in the same room at the same time.

Am I too old for this?

Your body does not check your age before it answers a challenging weight. Members here run from their thirties into their seventies.

What does the AI actually do?

It is an AI-based strength measurement system and it runs the training. The system reads what your body produces on every repetition, sets your load from that reading, makes sure you are in the zone we are aiming for and tells us when the set is finished. A trainer is still on the floor with you the whole session.

So I really never do cardio?

No treadmill and no running. Your conditioning is built into the lifting.

What should I wear?

Normal training clothes and closed-toe athletic shoes. Nothing special is required.

What does it cost?

It depends on how often you train and how long a term you choose. We go through it after we measure you, so the recommendation matches what your numbers say.

Is there parking available?

Yes — there is parking directly at 645 S. Beach Blvd.

How fast will I see something?

Six weeks, on paper, in the same six measurements we took on your first day.

Is strength training or cardio better for longevity?

Both muscle and aerobic fitness predict how long you live, and strength training builds both. Lifting with short rests raises aerobic capacity, and in a trial of dieting older adults, the cardio group lost more than twice as much muscle as the group that lifted. The full answer, with the research →

Why do you measure grip strength and balance?

Because both are tied to how long people live. Grip strength predicted death better than blood pressure in a study of nearly 140,000 adults, and adults who could not stand on one leg for ten seconds were far more likely to die in the following years. Why we measure all six →
