Hi!

WELCOME TO SWEAT & CALLUSES

I’m Niels Koster, the founder and owner of SWEAT & CALLUSES. Fitness and strength training have been my passion for as long as I can remember. Since a few years now, I'm also an avid CrossFitter. I created this brand to bring you the best gear that’s functional, built-to-last and simply straight-up badass. Our goal is simple: to help you reach your goals, while enjoying every step of your fitness journey. This isn’t a sprint, it’s a lifestyle – and we’re super excited to have you on board!

OUR JOURNEY & PHILOSOPHY

Picture this: music blasting, weights clanging, the sound of speed ropes, and the adrenaline of a tough workout. This passion for the gym, fitness, and CrossFit® is what sparked the creation of SWEAT & CALLUSES. We don’t just want to be a brand – we want to be a symbol of hard work, perseverance, and never giving up. Grit is in every drop of sweat we shed, and we wear our calluses with pride. Serious about training and our products, not ourselves. Because after all, it's not just about performance and results, but also about laughter, smiles and friendships.

OUR PRODUCTS

It all started with our large gym backpacks. These aren’t just ordinary bags – they’re your ultimate training partners. Style, durability, and functionality come together to make sure you’re always ready to smash your new PRs. Our rugged backpacks come with a free brand patch, but why stop there? Make your bag truly yours by adding extra velcro patches – little symbols of your hard work, dedication, and the fitness lifestyle you live. And that’s not all! We also offer wrist wraps and lifting straps, and we’re constantly working on developing even more awesome fitness products in the future.

JOIN OUR COMMUNITY

Our mission goes beyond just selling products. We want to create a mindset and a lifestyle within an amazing community of active individuals like you. So, come along with us on this exciting journey, embrace the grind, never back down, and let’s crush those fitness goals together. Whether you’re pumping iron in the gym or crushing WODs in your local box, consider yourself part of the fit SWEAT & CALLUSES family.
