Who is Fortress for?

Fortress is designed for women who want to protect their strength and mobility long term.

It’s especially useful for women who:

• Want to support bone density and muscle strength
  
• Prefer low-impact exercise like walking
  
• Are thinking about long-term health, resilience, and independence
  
• Want a simple, sustainable strength habit
  

You don’t need to be a gym person. Fortress works with everyday movement.

Why does adding weight help bone health?

Bones adapt to mechanical load. When your body carries extra weight during movement, it creates small stresses that signal the body to strengthen bone tissue.
Research shows that weight-bearing exercise and progressive loading can help maintain or improve bone density.
A weighted vest adds this stimulus while you walk, climb stairs, or train.

How heavy is the vest?

The vest uses modular steel weights so you can adjust the load.
Most people start with 2–4 kg total weight and gradually increase over time.

Is it comfortable to wear?

Yes. The vest is designed specifically for everyday movement.
Key design features include:

• Even weight distribution
  
• Breathable technical fabrics
  
• Adjustable fit
  

It’s designed to feel stable and comfortable rather than bulky.

How often should I use it?

Most people start with 2–3 sessions per week, usually during walks.
Over time you can build toward:

• Longer walks
  
• Heavier load
  
• More frequent use
  

Consistency matters more than intensity.

Is Fortress safe?

For most healthy adults, walking with light added weight is considered safe.
However, if you have:

• Osteoporosis
  
• Joint injuries
  
• Back issues
  
• Medical conditions affecting mobility
  

you should speak with a healthcare professional before starting.

Fortress is not intended to diagnose, treat, cure, or prevent any medical condition. It is not a substitute for medical advice. Please consult a healthcare professional if you have existing conditions or concerns.

How do I start?

Start light.
Add a small amount of weight and wear the vest during short walks and exercises. As your body adapts, you can slowly increase the load and/or duration.
The goal is simple: build strength gradually and consistently over time.

Where is Fortress designed?

Fortress is designed in Auckland, New Zealand. It was created to help women build strength now so they can carry that strength into the decades ahead.
