CrossFit® Caliber: Opinions

4.9/5 (45 Opinions)
Top Rated Gym
Miguel Angel Cortes 2 years ago

Fantastic experience: There is no doubt why CrossFit has become such a popular sport around the world - it is effective. With that said, all CrossFit boxes (aka gyms) will be unique in their own way. What makes CrossFit Caliber special is the people who go there to show their support. One can CrossFit anywhere but Caliber brings that positive outlook, that encouragement, that support that no other place in the world can bring. It won't matter who you are or how experienced you may be, all workouts will be challenging if you put 100%. The people at Caliber know what it means to bring it your all and that is why I have seen amazing transformations and improvements from everyone, including myself. Fitness will never be the same again - and I am grateful for that.

Fantastic experience: I have been going to Crossfit Caliber for 5 months now. I still remember my 1st workout. It only lasted about 10 minutes. I went home unsure, thinking how fast it was compared to the hour or more I put in at the regular gym, and wondering if it would be enough. Well, 2 days later I was feeling the delayed onset muscle soreness, and I was hooked. It's now 5 months later and I have noticed definite improvement in strength and agility. The cheers of encouragement from my fellow crossfitters to do more than I think I can keep me from quitting in the middle of a WOD, or taking it too easy on myself with lighter weights. I can push myself hard and not worry about the sweat, and the strange grunts that might escape me while pushing myself to do more, because everyone else is too. I also love that a few minutes are spent at the beginning of the workout going over proper technique. I highly recommend this gym.

Fantastic experience: Was traveling for Christmas and I jumped in for a two WOD's. Overall experince was exellent, good instuction and encouragement. Arnel and his staff were solid on technique and the drop in fee was resonable. Would recommend them for anyone looking for a crossfit box!

Fantastic experience: I have always been a person who works out but I never thought in a million years I would be able to get the results I have achieved with Crossfit Caliber! It is a great place to work out with the best instructors. I was very nervous going into my first Crossfit workout, but the group of people at Caliber are a very positive and encouraging group who make working out fun. The workouts are very intense and very difficult but they are worth it! If you come into Crossfit Caliber be prepared to become addicted!

Fantastic experience: Great gym with a great community! When I first joined this gym my intentions were to simply try CrossFit for a month. 2 years later I can’t imagine my life without this gym! Great programming with even better people. I can confidently say I am in the best shape of my life!

Fantastic experience: I came to CrossFit Caliber at a really tough time in my life. Here I found friends and a competitive environment that filled and fueled that lack off energy I had for some time. Now I start my mornings with energy, confidence and a positive attitude. I highly recommend it!

Bino Salazar 2 years ago

Fantastic experience: Such a positive and encouraging community! Just show up, give 100%, and be open minded to try new movements and workouts and the results will be there. In and out in one hour, all the programming is ready for you as if you have your own personal trainer. We know each others strengths and opportunities and grow together along the journey. Join us!

Fantastic experience: I usually don’t stick to any program so when I found Crossfit Caliber I needed to try it out more than one day. Arnel told me about bring a friend day in which I would be able to evaluate the program for 7 days free so I signed up. I like how the program is structured and the consistency of the instruction to ensure the workout is done correctly. The coaches are very encouraging and the community itself is a great group of people . I really like the program and I am actually attending 3-4 times a week which is a record for me. I am planning to continue with the program which I highly recommend!

Samantha Padilla 2 years ago

Fantastic experience: This is my home away from home. I have been a member of Caliber for 4 years now and I honestly can’t imagine going anywhere else. The great thing about CrossFit is you can be any fitness level and still complete the workout. I have fluctuated in weight and body shape since starting - I have seen myself in the best shape of my life before my wedding, did CrossFit all through my pregnancy and am now back postpartum all with Arnel and his coaches help! The members and the community make it easier to get up and get to the gym every day. Highly highly recommend this gym and CrossFit in general to anyone!

Positive experience: I am a new member and I have realised that people are really welcoming, kind and nice. It is a wonderful group of people who support you and help you.

Dagmara Cydejko 2 years ago

Fantastic experience: Great gym and wonderful people. Caliber coaches helped me get fit and safely learn Crossfit movements. I really recommend to check it out.

greg karesh 2 years ago

Fantastic experience: I am 33 years old, I’ve worked out my whole life, but just recently joined Caliber Crossfit three months ago. I consider myself pretty well informed when it comes to creating workouts for myself but I did not know until recently that I have missing out on the best and most beneficial workouts in all areas of fitness until now. I can’t stress enough how valuable these intense workouts are to me in my every day life. If you’re looking for a great community as well as great workouts this is 100% place to go.

Teresa Dyer 2 years ago

Fantastic experience: My experience at Crossfit Caliber started from way back when groupon was popular to try out new things. I didn't know what Crossfit was all about but it was a great way for me to find out. I used to go to work out at LA fitness for years, like clockwork, an hour a day but got no result. My health goal was achieved in Crossfit. Working out at Crossfit Caliber got me hooked. Not only Arnel, the owner and all of his coaches are very attentive to the correct forms on handling weights that would prevent injury, we also learned nutrition value to build and maintain muscle mass. The mobility class really hone in to the technique of stretching and different ways to lessen muscle soreness. What I love about Crossfit Caliber is this community is small and friendly, you got to know everyone there and it is like one big workout family. Most Crossfit workout are short and intense. At Crossfit Calibre, I always got a good workout. Each workout of the day is different, I always looking forward to the surprise on what the workout of the day bring, it's a thrill of not knowing that make Crossfit interesting.

Fantastic experience: I usually drop in whenever I’m in town. The coaches and staff here are extremely friendly and knowledgeable, the coaching during workouts was superb. The patrons are extremely welcoming to all fitness levels. Highly recommend this box.

A C 2 years ago

Fantastic experience: My wife and I both experienced other crossfit gyms before coming to Caliber and there is absolutely no comparison. This box is literally in a "Caliber" of its own. Not only an amazing way to get in better shape safely and effectively but the group itself ended up being so much more than just a place to workout. Its a family. The owner, Arnel, and the rest of the coaches all make sure every movement you make it done correctly which is very important with every aspect of exercise. Try one class and you'll be hooked for life.... Anthony C

Jonathan Wentworth (Jonathan) 2 years ago

Fantastic experience: I can't say enough positive things about CrossFit Caliber! The trainers are very knowledgeable and you get plenty of individual attention, for someone like me who had never done CrossFit before, this is very important to avoid injuries and to get the most out of the workouts. Excellent atmosphere, it really feels like a family! They are competitively priced when I compare them to other gyms (I've done Burn Boot Camp, and Fit Body Boot Camp). If you've never done CrossFit , I would highly recommend this place. If you're a CrossFit pro, I would highly recommend this place! The members all have varied levels of experience, from newbies like me to people who have done CrossFit for years.

Heather Mendez 2 years ago

Fantastic experience: Whatever your fitness level is this place will challenge you and help you achieve your goals. I have gone through two pregnancies while working out here and remained healthy with the guidance of the coaches. The community is super supportive and I love coming here.

Angela Vick 2 years ago

Fantastic experience: No matter your fitness level, you need to check out CrossFit Caliber!! I am absolutely glad I did. I had never done CrossFit before and was curious but a bit nervous trying something new. From the moment I walked in, I felt welcome, encouraged and motivated. I just can't say enough about the positive community that this gym has, from the owner, coaches and members. I've not only surprised myself on what I am physically capable of but I am genuinely excited to go everyday!!

Fantastic experience: CrossFit Caliber is my home away from home. The people and training here have changed my life in the best way possible. 10 out of 10. I highly recommend you check them out.

Melissa Wolf 2 years ago

Fantastic experience: Great gym! Awesome coaches!! While some think Crossfit is intimidating this box will put you at easy. You can have no experience or a Crossfit lifer and you will fit right in. The coaches always have a modification for you that will still get you a great workout.

Kristina Salazar 2 years ago

Fantastic experience: I was very skeptical about doing Crossfit, and in fact so much that my first class I was certain I would never go back. BUT, the crew and owner of Crossfit Caliber were so amazing that I gave it another shot and am so glad I did. Caliber is beyond just a workout, it is an amazing community. Owner Arnel and his wife Micki are amazing people and are so encouraging it's hard not to love it. Our entire family currently goes to Caliber and I can't imagine not being there. Arnel goes above and beyond of what most gym owners would. Give it a shot, I promise you you won't regret it!

Jamie Serena 2 years ago

Fantastic experience: CrossFit Caliber is a great community with supportive and encouraging coaches that help you work towards your fitness goals! The community is very positive and fun! This makes consistency easier as you receive support and motivation from other members in addition to the coaches.

Hilary Martin 2 years ago

Fantastic experience: I have been a member of CrossFit Caliber for almost three years. If you are looking for a place to call home, this is it. No matter where you are on your fitness journey, the coaches meet you and help you transform into the best version of yourself. The class sizes are perfect, the programming is interesting, and don’t be fooled - you will get kicked into shape and you will surprise yourself with how much growth occurs! Additionally, the people you meet at this box are some of the most kind, caring, and loyal people around. It is a wonderful group of people who support you, love you, and cheer you on. They make both the oldest and newest members feel welcome. Finally, the coaches are phenomenal. They are friendly, knowledgeable, and capable of guiding you through your workouts. They help you scale if needed and they don’t ever make you feel less-than if you can’t quite nail a skill (though they will push you if necessary too). Arnel definitely knows what he’s doing, and he’s doing something right!

Lisa Stegmiller 2 years ago

Fantastic experience: I have always been just a standard gym girl. I love taking different types of fitness classes and enjoy variety in my workouts. CrossFit has always interested me though, and when my neighbor told me about Caliber, I had to give it a try. Now that I am a member here, I’ve never felt more of a belonging in a community. The coaches are very patient and helpful with form. The workouts are like nothing I’ve ever done before and they always push you to your limit. The mental and physical challenge that CrossFit brings is unmatched. So glad I found Caliber!

Elgin Krusers 4 years ago

Fantastic experience: I’ve tried many CrossFit gyms in the Chicagoland area… This gym is not the closest to my home and it is also not the biggest. However, the community and the coaching plus the individual accountability that I get from this gym are superior to anything I get anywhere else. Arnel is an excellent coach and motivator. Highly recommended.

Kevin Kazmierowski 4 years ago

Fantastic experience: CrossFit Caliber is so much more than just another gym. It is a unique community of motivated, friendly and active people.

This is an excellent place to improve your fitness at your pace and meet some awesome people along the way.
