Program Description

The 21-Day Challenge strikes again! We started doing 21-Day Challenges in our gym in 2015, with hundreds of members enjoying shocking themselves with their undeniable results in only three weeks.  We're very excited to bring you this new edition.


Classes range from 27-48 minutes, with an average class length of 35-minutes. (Strength days are longer classes, conditioning and active recovery days are shorter classes.)

Only one "medium" weight kettlebell required but bring more if you have them.

Optional extras: yoga mat, sweat bands for your wrists, jump rope, stick/pole for mobility. Classes in this series range from 30-45 minutes each.


This strength challenge begins and ends with a "baseline" test, and each week follows a course of expertly planned workouts that allow you to create the habit and instant feedback from working out daily without over-training and burning out. 

Hundreds of members have completed the before and after tracking sheets, and often doubled the amount of volume they were able to do at the end of the 3 weeks. Not to mention enjoying fat loss and newly visible muscle tone.

Who It's For

In The 21-Day Strength Challenge and as often as we can in all our workouts, we offer modifiers to make the exercises accessible to as many people as we can, but this program does contain longer sets of more technical kettlebell exercises like jerk and snatch.

For best results and for your safety, please take the Rookie Challenge or have equivalent experience and understanding of the kettlebell swing, clean, jerk & snatch prior to starting this program.


Challenge videos are embedded on this website on your training program page (you'll need to create an account at checkout). FYI, this is a separate system from the Pro Kettlebell Workouts App.

For easy viewing, we like to screencast to a TV but it still works from a laptop or computer - whatever you prefer.

You'll get to mark your classes complete as you go and enjoy watching the progress circle close. And here's an important piece of motivation to help you complete the challenge: it's 22 days with an extra week of access added so you have a little buffer time to start or finish if you need it... but access does expire permanently after the 29th day!

Online Coaching

There's no motivation to show up to your workout and do your best like having someone waiting for you.

Even better is when the person waiting can help you improve your technique, know which weights to use, find the right modifiers if you're working around injuries, and teach you the best kettlebell lifting techniques for your body type to get the specific results that you want.

Online coaching appointments are scheduled with Pro Kettlebell Owner and Head Coach Nikolai Puchlov. You'll work together to find a convenient & available time for your sessions 4:30a-6:30p PST Mon-Fri. After purchasing, we'll reach out to schedule, but feel free to send him an email right away with your preferred times.

And don't worry, if you aren't able to find a time that works for both of you, online coaching sessions are fully refundable, so long as you initiate the return within 30 days of purchase, and prior to any of the sessions being scheduled. Please note there are no refunds for completed or missed sesssions.

Can’t access my account.

Hi Mary,

I’m so sorry to hear you can’t access your account. I know you had trouble logging in initially, but after posting your previous review that the classes were too hard for the over 70 crowd, I assumed that one of my previous emails had helped and you had gained access.

I know the free access I gave you through the website and the Pro Kettlebell Workouts App has already expired, but you should still be able to login to your account. I’d be happy to troubleshoot over the phone. You also still have free access through the direct link I emailed you last week, so that will be your fastest and easiest way to access these classes.

I very much apologize for the trouble and am especially disappointed since I was trying to take extra care of you by giving you free classes in the first place. I’ve never received a 1-star review in 10 years of running this business and customer service is very important to me, so I would really like to resolve this and make you happy.

I feel strong

I have really appreciated the pro kettlebell workouts.
The instructions are clear, the positive coaching makes it fun, and the stretching means
I don’t get hurt. I feel strong and I am keeping my sanity while working at home with my
kids. Love it!

LOVE LOVE the online courses, since the gym was quite a drive for me. Pro Kettlebell is a higher quality on-line class from several others I have done. Having the narrator in addition to the instructor is so much more professional making it easier to stay in sync. Demonstrations of each move before the block also helps me maintain consistency in my workout. I am so grateful for the opportunity to work out at home with high-quality KB Sport professionals.
