"I love that each workout focuses on all aspects of health—physical, spiritual, and mental. Michael’s programming is perfectly balanced between stretching, strength, breathing, and being aware of your body & mind. Britt’s workout videos are uplifting and encouraging. I recommend KB Solo to anyone who wants to work on their functional fitness and maintain a healthy lifestyle that is sustainable & long-lasting."
— Mary V.
"Kettlebell Solo is a dream come true. The level of expertise from Britt and Michael is hard to find anywhere else. I appreciate the convenience of doing workouts from home, which saves time in my busy work day. The classes are easy to follow and fun! The best part is the results - I’m stronger and better toned all over."
— Anne C.
“Kettlebell Solo helps this 63 y/o with activities of daily living: bending down to scoop up my dog, reaching up high to put away dishes, etc. I think your practice will keep me limber enough to do these daily activities in the long run. My mood is uplifted, I’m getting stronger, and my balance and coordination are improving. Seniors like me can benefit from this program.’’
— Mary S.
"When I started, I felt old. My flexibility was poor. I couldn't even do one pushup. Now, I feel good. I can do multiple pushups and I am no longer out of breath during classes. I have not had back pain for a while. My mood and energy are noticeably higher."
— Abi L.
"I’ve always wanted to use kettlebells but I was intimidated by movements like the Snatch and Turkish Get Up. They just looked so technical. I’ve been a KS member for months now and love it. Brittany and Micheal are amazing and keep us motivated. I’m 63 and feel great; this program is for all ages. If you’re curious about using kettlebells, Kettlebell Solo is the program for you!"
— Mary Jo B.
"I’m 54 and have been strength training since my 20s. I love Kettlebell Solo, as it aligns with my value to listen to and respect my body. Honoring myself is an ongoing journey for me. By learning to listen to my body, I am becoming a more whole person mentally, emotionally, physically, spiritually."
— Anne W.

Frequently Asked Questions
Is Kettlebell Solo for me if I’m new to kettlebells, or returning after time off?
Yes. Kettlebell Solo is designed to meet you where you are, whether you’re brand new to kettlebells or coming back after a break. Many of our members start with little to no kettlebell experience, or after time away from training.
Our programs emphasize clear instruction, thoughtful progressions, and full body exercises that build confidence over time. You don’t need to be “in shape” before you start — the training helps you get in shape, safely and progressively.
Is Kettlebell Solo safe for my joints, back, and knees?
When strength training is coached and programmed well, it’s one of the best things you can do for joint health.
Kettlebell Solo focuses on controlled, intentional movement — so you’ll build strength through your hips, core, and upper body in ways that support your joints, rather than stress them.
With over 30 years of combined coaching experience, Britt and Michael emphasize good technique, appropriate kettlebell weight, and smart progressions so you can train with confidence while honoring your body's needs.
How is Kettlebell Solo different from high-intensity or “bootcamp-style” workouts?
We don’t believe you need to crush yourself to make progress.
Kettlebell Solo is built around the idea that strength training should leave you feeling more capable — not depleted. Our workouts prioritize quality over quantity, recovery over burnout, and sustainability over intensity.
Rather than pushing through pain or chasing exhaustion, we're here to help you build strength that supports your life, respects your body, and enhances long-term health.
How much time do I need each week to see results?
You don’t need hours a day to benefit from strength training.
Many KS members see meaningful improvements training a few times per week, 10-20 minutes per workout.
Kettlebell Solo offers a range of class lengths and program styles, so you can choose what fits your schedule and energy.
Consistency matters more than intensity — and the goal is to build a routine you can sustain in the long run.
How do I know which membership option is right for me — Basic or Premium?
Both options give you access to the Kettlebell Solo training library — the difference is the level of guidance and support you want.
The Basic Membership is great if you’re comfortable choosing your own workouts and prefer flexibility. You'll have access to 120+ classes, 3 programs, and Members Only community.
The Premium Membership is ideal if you want more structure, coaching, and ongoing support to help you stay consistent with your training. You'll have access to 280+ classes, 20+ programs, challenges, 2 onboarding calls, and Members Only community.
There’s no wrong choice — both are designed to help you build strength safely and sustainably. Many members start with one option and adjust as their needs evolve.
What kind of results can I expect from Kettlebell Solo?
Most members notice changes that go beyond appearance. With consistent training, our members report feeling stronger, more balanced, and more confident in their bodies. Everyday tasks — carrying groceries, getting up from the floor, moving through daily life — start to feel easier.
Over time, you can expect:
Increased full-body strength
Better balance and coordination
Improved posture and mobility
More energy throughout the day
Greater joint strength and resilience
More confidence in yourself
Some women notice changes in how their clothes fit or how their body feels overall, but Kettlebell Solo isn’t focused on quick transformations or extreme results. The goal is sustainable strength — strength that supports your health, energy, and independence for years to come.
Progress looks different for everyone. What matters most is building a strong, capable body that you can trust and have a harmonious relationship with.
