Are you...

A kettlebell user who is well-versed in kettlebell training?

Finding yourself doing the same kettlebell workouts over and over again?

Looking to follow a progressive program instead of doing random workouts?

In search of a program that incorporates the fundamental kettlebell movements?

Stuck without gym access and minimal space to work out at home?

Searching for an exercise program that is both efficient and effective?

Wanting a program you can do indoors, outdoors, or even in the living room?

Exposure to kettlebell training is growing--they're fun, versatile, compact, and, most of all, extremely effective. Whether you're trying to bring your kettlebell game to the next level, or you're already a kettlebell machine and want a challenging program to follow, you've come to the right place.


Coach Rebecca built this program to level you up.

"Kettlebells are my passion, and I want to share my passion with you. Let's build better and stronger movements. Whatever your foundation in fitness, kettlebells can make that foundation stronger. That is why I call this "Built By The Bells".

...it has helped me surpass every strength goal I had set for myself.

I often say I want to be one of those “kettlebell people” that I follow on Instagram, but have always felt that to be so far out of my reach. Working with Semper Stronger and Rebecca has not only changed how I think about kettlebells mentally, but has helped me surpass every strength goal I had set for myself. I like change and fast paced, kick-your-butt workouts, and this program has been exactly that. Rebecca has a way of stepping up each move from week to week in a way that keeps it fresh, and before you know it, you're lifting heavier and heavier kettlebells. I can honestly say I looked forward to each day’s workout. They became more of a mental and physical challenge than something I just needed to check off each day. I am now one of those amazing “kettlebell people,” thanks to Rebecca and Semper Stronger.

I learned how to use kettlebells from following one of Semper Stronger's programs. Each week I got stronger, better, and more confident with the kettlebells. Since I finished that program, I had been looking forward to the new Semper Stronger kettlebell program. I got it as soon as I could. I'm only half way through it, and I'M LOVING IT!

The video demonstrations are awesome; the progressions are spot on; and the new app is so much better.

Thanks for releasing quality programs, Semper Stronger.
