Castle Rock Shred415’s signature class is based on four, fifteen minute segments, alternating between treadmill drills and strength training, plus onsite childcare. In every class, you’ll always do an equal amount of strength and cardio. You’ll select your weights and set your speed on the treadmill, and your instructor will challenge you to work up to your next level—at a pace that works for you.

Nicole Runels
I am very happy at this gym. I love the variety of cardio on the treadmills and strength training on the floor. The teachers, staff and sense of community is so great and motivating!
Doris Muentes
Love Love shred 415 class kick my butt which I like. And all the team members are
Great.
Nicole Muller
I have tried so many gyms and Shred415 exceeds them all! From your first workout you truly feel like you are apart of a community! The workouts are amazing I started seeing results after the first week! If you’re thinking about trying it just sign up you won’t regret it!
Michelle Hetterscheidt
I love this place! I am use to doing at home workouts, but when I started here, it was amazing! The workouts are effective. I’m now lifting heavier than I’ve ever lifted. I’m running on the treadmill, which I’ve never done. Plus the community is amazing!
Jen Kaminski
I love the energy of this workout! Plus it’s scalable…whether you walk or run, lift heavy or lift light, jump around or keep it low impact, this workout works for you!
Breann Smith
I've been attending this gym for nearly a year now, and it's been an incredible experience from day one. The instructors here are not only knowledgeable but incredibly welcoming — they know me by name and always greet me with a smile. The variety of classes is fantastic, ensuring you never get bored. As someone who isn't a huge fan of running, I've found comfort in their walking-focused workouts while still getting a great workout. They offer different class formats tailored to endurance or strength, which is perfect for personalizing your fitness journey. And they have a kids club so you can drop off your kids and get a great workout! Highly recommend this gym for anyone looking to stay motivated and have fun while working out!
Craig Cornichuck
My second review was about 11 months ago. My third review. I’m less than two weeks away from hitting 900 classes. I’m excited for the next 100 to 1,000 classes. This is such a great workout communtiy and you should find a way to be a part of it. The instructors and fellow Shredders are great. I’m thankful that I’m able to attend these workouts.

My first review was roughly two years ago. And if you told me two years ago, I would be on the verge of completing 600 instructor led High Impact Interval Training classes at Shred 415 in Castle Rock, I would have told you that you that you were nuckin’ futs. Here we are.

Somewhere along the way, between the burpees, reverse lunges, hollow holds, AMRAP’s, EMOM’s, and Punk and Taylor Swift playlists, I discovered a community of instructors and Shredders committed to health, fitness, and wellness for not only themselves but those around them.

The alarm clock rings in the 4am hour and I don’t think twice about getting up and getting myself to Shred.

I love how I feel when I am in this studio.

Five point Zero stars doesn’t sufficiently state how grateful I am for the instructors and Shredders in this community. Not even close.

If you’re looking for someplace where you can lean into health and wellness with the support of instructors and Shredders around you, you have found your home.

1st Review. Love the workouts and how I feel after them. Can feel and see changes in my body for the better. Would recommend Shred workouts to my friends and family.
Haley Maguire
Shred is hands down the best group fitness experience I’ve ever had! I really appreciate how the gym is judgement free and accepts people wherever they are at in their fitness journey. The workouts fly by and there’s a never a feeling of being lost in the shuffle. I like that I can get both my cardio and strength workouts in the same session. The instructors are the best and the community is incredible. Highly recommend giving it a try!
Kelly Webster
Great staff and amazing workouts!! everyday is different and it never gets easier. Highly recommend Shred415 Castle Rock.
Andrew DeFrancesco
I like this place but the hours offered aren’t great. Really wish they had afternoon classes available especially for those of us that get off from work between 4-5.
Katie Kickhafer
I<3 shred. I was an avid class pass user until I found Shred415. Everyone is so welcoming and inclusive. It truly feels like a safe and supportive space to work towards fitness goals. Shoutout to Sydney and all of the amazing instructors that make the classes fun and motivating. I appreciate you all! 😊
Sarah Jimerson
Shred 415 is the best! If you want a work out that is challenging and fun, this is for you! But its the welcoming, fun community of people that truly makes this place special! Sydney and Maddie are amazing! Also the childcare is great!
SMS® Denver - Boulder
As a business owner myself, I am so impressed by the space created have an incredible workout and feel SO supported. They even have a Kids room, so sign up to get childcare included!! We LOVE Shred415 Castle Rock!!
Hannah Summerhill
I truly cannot say enough good things about this place. The classes and instructors are great. 45 minute express classes or 1 hour, always focusing on a specific muscle group or full body. Every single instructor is encouraging and knew my name after just 1 class. The membership prices are reasonable and I am always excited to take class. On a personal note, my favorite instructors reached out with support and well wishes when they knew I was going through a rough time, and I just feel so lucky to have found this place. Sign up for a class - I promise you won’t regret it!
Sydney Baker
If you’re looking for a good workout, fun community, and child care, Shred415 is the place to be. It is the best!
Sarah Neylon

Stacy Dreessen
Love the Shred community. Kara,Abby and Syd are some of my favs
Rachel McDonald
Love working out here! The classes & instructors are fun and they are always motivating you to push harder. Ive never been stronger!
Laura Brown
I have been a member at Shred in Castle Rock since they opened their doors in October 2019. I was hooked instantly by the energy and intensity. The owners are just so kind and the coaches are electrifying. I have found a family in Shred, both in the instructors and the classmates. They have helped me stay active during pregnancy and recover my fitness level postpartum. I've been able to set high fitness goals and achieve them. The workouts are tough but they give me that boost that I need in my day. The facility is clean and welcoming and there is such a cheerful, supportive atmosphere. It's just my favorite!
Jocelin Lehner
This gym is awesome! The staff is so nice and so is the overall community who attends classes. The workout is challenging, motivating and fun. I also love that the facility is always very clean. Would definitely recommend!
Christi Nowakowski
The energy and vibe of this workout is fantastic! Coming from a girl who hates running, I did not think I would enjoy this concept. But the intensity, speed and difficulty is changing so frequently that the time flies by and when you don’t think you can push yourself harder, these girls show you that you can. Every little change, every little push matters and this team shows you that every day. You can do anything for 15 minutes at a time!
Steven OBrien
Great workout! Encouraging instructors. Customizable to all fitness levels. Addicting in the best way.
Glen Roberts
Great instructors, front desk and members. I’ve made many friends at Shred!
Cara OBrien
I’d give this place a million stars if I could! The workouts are challenging and fun, the instructors are motivating and fun, and the people who attend classes are nonjudgmental and fun. But more than all that, the sense of community is unsurpassed. People support each other, celebrate each other, and lift each other up when needed. It truly is more than a workout.
Julie Malone
Life changing workouts that challenge you to be in the best shape! They offer childcare. The instructors are all incredible and motivating! There isn’t anything like shred 415. First class is always free! P
Justin Frohnhoefer
New:
Since the beginning of 2024 I've worked out pretty religiously at Shred415. Not only have I lost weight, but I can lift significantly more and have a lot more endurance when it comes to running/sports.

If this sounds like something you want to achieve, I recommend committing a few hours a week to Shred! Plus, the community is the best part. Everyone rocks!

Original:
My wife has been going to Shred415 for almost a year now and although I have met her great new group of Shred friends, I hadn't gone to an official class until today. I frequent the gym where I have my own weight lifting and cardio routine, but in their environment you hold yourself accountable and push yourself to the next level.

Everyone there is so warm and welcoming it's like a big workout family. They deserve 10 stars!
Rosalie Boyle
The instructors are amazing. Every class is different. You walk in, and the hour flies by. Also, they do so much to connect with each other and have such a sense of community. THE best gym in Castle Rock, hands down.
Lindsey Smith
Shred is my home away from home! I’m absolutely obsessed with each and every class and it has gotten me back in shape and the best shape of my life, post baby!
A T
Awesome place!!!! 10/10!! Great instructors with amazing equipment and great variety of classes!
Emilee Hazen
I was invited by a friend and now I’m obsessed!! I had a baby 3 months ago and these workouts make me feel so good!
nicole nij
Best work out you can get in 60 minutes and I always end up pushing myself harder than I ever would on my own! The time just flies by! The energy at Shred is beyond amazing, I always leave feeling so good about myself. The staff & teachers are truly great people, they all know me and my kids by name. Such a great feeling when people care about you as a person. I love that they provide childcare, perfect for all the mommas!
Angela Dzialo
A great workout that provides a good variety. The instructors and staff are top notch!
Shervin Radfar

Back from London and could not find my gym. Until I found Shred. Dimly lit. Clean. Minimalistic. Perfect. And kicks my butt. ❤️
