This is the most fun I've ever had at a workout class! It's always a little nerve-wracking trying something new, but that did not last long the first time I came here. Such a welcoming environment. I pretty much decided 5 minutes into my first class that I would be returning. All the instructors are so talented and fun. I have never left this studio without a smile on my face. There really is not anything quite like this place! 11/10 would recommend.

I cannot say enough good things about Block21! This studio is incredible, the instructors are so energetic and friendly. From my very first class, I felt as if I were a part of a community that actually wanted to get to know me. Every class here is so positive and leaves me feeling so good about myself. This is such a special space, and I highly recommend classes here to anyone who is interested in a laid back supportive environment. I was incredibly lonely and depressed during quarantine, and going to Block21 completely changed my daily life. Thank you to this incredible studio for saving my mental health, I am so grateful. Take a class here, you will love it!

I really really wanted to enjoy this experience. I booked the signature class which is described on the website as the best class for beginners or for people who are new to Block21. This class is very far from a beginner class. I had to leave 1/2 way through the class because things just kept getting more challenging and faster as time went on. The choreography is fast — very fun, but with no explanation, it’s hard to keep up. I really tried to have a good time, but unfortunately it’s hard to have fun when you’re absolutely lost. The choreography was also very feminine-feeling, (lots of twerking, bend and snaps, and chest shimmying) which made me really uncomfortable as someone who isn’t super comfortable in their body as a transmasc person. 😓

I'm new to Denver and was seeking more places to find community. I'm so amazing grateful I found BLOCK21! The teachers are all unique in their styles and approaches... but none fail to bring amazing energy. Everyone was so welcoming on my first day and I'm pretty new to the studio but it already feels like a home. Every class feels like a party (yes you can party Mon - Sun at BLOCK21)! If you love it as much as I do you will get the Unlimited Membership... at first it seemed like a huge investment but it is honestly an amazing deal and well worth every penny. I really could go on and on... just know you don't need any dance background to come... all you need is some great energy, a willingness to shake your butt... maybe feel a little silly sometimes... I promise you will NOT REGRET taking a class. Huge thank you to BLOCK21!

Love this place! Such a fun dance workout with awesome instructors all-around. This place has helped me improve my confidence and gives me something fun to look forward to throughout the day.

Unbelievable! I am a Personal trainer & Group Fitness instructor and this is where I choose to work out! The instructors are excellent, the music is fire and the dance moves are so fun! 100 out of 10! This is the place to shake it!

This place is amazing. The instructors are so much fun, the atmosphere is upbeat, and the culture is one of support. It's a hell of a workout that just feels like having fun with a bunch of badass people. 💚

There's a good reason why this place has 5/5 stars review on Google! It is one of the best workouts in Denver! It's choreography based cardio fitness! It feels like you're dancing in a club but in tennis shoes instead of heels! Everyone at the studio is sooooo nice and no one cares at all how you dance! It's a great place to fully express yourself and be yourself in dance. I look forward to it every week because it's a wonderful workout and the ultimate endorphin release!

On the positive, Great instructors, great environment and good vibe, I'm definitely sweaty at the end of class. On the areas to improve, I wish the songs rotated more often, it can get repetitive to dance to the same songs over and over. Also wished the workout intervals were more planned, seems like they're just whatever the instructor thinks up that day

This is the most fun workout that I've ever experienced!! Be patient and give yourself 10 classes to learn the movements and how the instructors present the choreo. Your mind/body will adjust and things will come together. Try every teacher because they all bring something different and interesting to each class! Such a good time, super welcoming atmosphere and I can tell a major difference in my body (especially cardio wise).

Had my first class with Emily and I had THE BEST TIME! I grew up dancing but haven't been able to find the style of workout that I've been searching for until now. The music...the lights...it all makes me feel less self-conscious and for the first time in a long time I was able to truly dance my heart out. I can't wait to go back!!

I am absolutely obsessed with Block21! I love that it feels more like a dance party than a workout, plus I’m burning close to 500 calories every time. Every instructor is amazing in their own right. The owner Sally is a gem, and I can tell it’s more than a business for her. Her compassion and acceptance flow through the whole Block21 community. I love to be a part of it! Come check it out, you will not be disappointed!

BLOCK21 is my favorite part of my week. It’s the most fun way to sweat, laugh and build the self-love that you deserve. The class moves fast and may take a few to get the hang of it but then you’ll fall in love. Mo, Kenny and Sally are my amazing usual instructors but you can’t go wrong. I did a private class for my 30th birthday and now my friends can’t wait for my 31st!

My absolute favorite workout and has also been loved by “non dancers” I’ve dragged along. If you’re really scared you can start with a virtual class but honestly just show up. Everyone is nice and dancing is the biggest mood boost of my week. Never have to drag myself there like the gym!

I can’t rave enough about block21! When I moved to Denver I was looking for a fun workout and this is the only fitness place I’ve signed onto after the initial trial. The vibes are immaculate, there’s something about a room of women vibing and dancing and working out that just gives me lifeeeee. I’ve taken classes with multiple instructors and they’re all great and talented, but Emily’s energy is the bomb and makes it feel like we’re all going to the club together

Seriously the most fun you can have. So hard to believe you’ve done a workout class because it feels like you’re in the club with your besties. Wish I could go daily. The staff is kind, inclusive, and talented and the owner, Sally, is a true visionary! This is a must do in Denver.

John was absolutely INCREDIBLE!!! You HAVE to try his class. The energy, music and overall vibes were SO SO fun and exhilarating! Do yourself a favor and GO!

I always look forward to going to Block21! The atmosphere is supportive and non-judgemental, and the focus is always on having fun over being perfect. This studio has made me feel more confident and helped me reach my fitness goals. Thank you Sally, Emily, Quiana, Julia, Monica, John and Mark for creating such a special space! <3

Easily one of my favorite places in the world! Stumbled onto Block 21 through Classpass and got addicted! Now I’m a full time member and coming to class is the highlight of my day! Music is fire, the instructors are full of hype and the nicest people ever. Dances are super catchy and it’s a great workout! Can’t say enough about Block 21, I bring all my friends and highly recommend this place to anyone who likes to dance!

Block21 is always the highlight of my week!! The vibes are immaculate and it’s the perfect balance between a difficult cardio workout and a fun dance party. I’ll never stop going!

Super fun dance-cardio workout! Body positive atmosphere has helped my self-esteem. Been a member almost a year. Appreciate that they get involved in community events as well.

I’ve never had so much fun working out. John was phenomenal at leading the choreography and checking in to keep me pumped! I’ll definitely be bringing my girlfriends next time!

This weekend was my first Time taking a class and wow it was so fun! I don’t take a lot of fitness classes and I’m not the best dancer, but Emily made me feel so comfortable! I was laughing and smiling the entire time. 11/10 I recommend signing up for a class! I will be sure to be back.

I just love this place. As a former dancer, I can be pretty picky about dance classes - and I’ve tried a lot of them! Block21 is my favorite “dance workout”, but it doesn’t feel like a workout at all (the best way to do cardio in my opinion)! Every instructor is a little bit different, and while they’re all great, my favorite classes are with Sally, Kenny and Quiana. Block21 is more than a workout. It’s given me a place to let loose, have fun, connect with my body, and feel more confident as a result. Beyond that, I’m proud to support a female-owned local business in the Denver community. Highly, highly recommend coming in for a class - you won’t regret it!
