A MESSAGE FROM THE FOUNDER

A MESSAGE FROM THE FOUNDER

As a lifelong fitness enthusiast from Boston, I’ve always believed that a well-equipped gym is the foundation of every great fitness journey. I started Sweatfully after helping my mother build her home gym—and after years of running a zero-emissions landscaping business and a gym clothing brand, I knew there had to be a better way to outfit fitness spaces.

Sweatfully.com was born to simplify that process. Whether you’re building a home gym or a large commercial facility, we bring you a carefully curated selection of top-tier equipment, flooring, lighting, and accessories—all from trusted, name-brand suppliers.

We’ve connected over $1.15B worth of product, ready to ship directly to you. You read that right, over $1 billion dollars worth of in-stock inventory. No quotes. No delays. Just fast, reliable outfitting built for serious results.

We’re proud to be the first brand dedicated to connecting health and wellness facility products all in one website. I personally attend trade shows, vet suppliers, and build partnerships to ensure every product supports your growth.

If you have any questions about the Salsbury Maximum Height Free-Standing 4C Horizontal Mailbox with 20 Doors and 2 Parcel Lockers in Black with Private Access or your gym buildout, reach out—we’re here to help. As we grow, I’ll make sure Sweatfully keeps its personal touch while scaling to serve gyms nationwide.

Thanks for being part of our journey.
