Fantastic experience: I absolutely love the community at Sideyard. Everyone is so encouraging, positive, and friendly. The members and coaches motivate me on a daily basis.

Fantastic experience: Amazing coaches and awesome people! They are very good at making sure your form is correct and you don't injure yourself. Just started in April but already feels like my 2nd family!
Fantastic experience: This place is actually the best! I was super hesitant to join CrossFit at first because I had never even been to a gym and wasn’t sure I would be able to do it but the coaches and everyone there are soooo friendly and make sure that you’re comfortable and are a great support! They super flexible and make sure that you know what you’re doing so you’re safe (that might be the best part) and adjust the workouts to fit your ability and comfort level but at the same time they’ll push you so you can progress. And they make it fun! I’d give them 10/10 if I could:)
Fantastic experience: Sharene is great! She has helped me tremendously on my journey to be healthier and I have gained tools from her that I didn’t previously have. I couldn’t recommend her enough!

There is also great camaraderie amounts the members in the class. Everyone is there to support everyone else. I did not expect that but it has been very up lifting. Give it a try. You’ll love it.

Fantastic experience: I love going to CrossFit at SideYard Crossfit. It’s more than a place to work muscles you never knew you had... it’s family atmosphere. Everyone is supportive and encouraging. I’ve seen great results in just the six weeks I’ve been going! My 8yr old also does the kids class and he really enjoys it.

I’ve been pushed to new limits because the coaches are experienced and pay close attention to each and every member of the class.

The classes are fun and the relationships we’ve built help us stay accountable. I’ve been doing CrossFit for 7 years and I can say that I’ve never had the amount of structure that is built in to the programming. There are modifications for everyone when needed but there is coaching to improve your abilities and if they know you can safely do something they hold you accountable, which I love. Very thankful for this community of people and I highly recommend giving this amazing place a try.

They are super supportive, right down to doing workouts right beside you to cheer you on! They are crazy knowledgeable and just plain good people! It is a fun, hard place to work out, and I love it!
Fantastic experience: I'm so lucky to have found this place! The community atmosphere is wonderful, and the coaches are excellent about challenging athletes when needed, but also offering modifications as needed. The perfect balance!
Fantastic experience: I was a member of Sideyard training for about 8 months. The atmosphere was awesome and I learned so much and got stronger so quickly. I then find out I was moving and the place I was moving to did not have a CrossFit gym. I contacted Sideyard and they were more than willing to help. I was able to continue my workouts through their Wodify app. It was convenient and they were always an email, a text, or a phone call away off I needed anything. If you are looking for something different but don’t have anything offered in your area…. I would highly recommend contacting Sideyard!!!!
Fantastic experience: This is my first CrossFit experience and it has been awesome! The coaches are motivating and so good at what they do. I feel challenged each time I go and feel so much support from the coaches to be able to accomplish whatever the workout goals are. I love the variety of workouts offered. The facility is always kept clean with a great atmosphere and really friendly people. It’s always a great way to start off my day!
Fantastic experience: Positive: Communication The owner of this gym (sharene) Is one of the most Caring , loving and dedicated trainers I’ve ever met… She helps everyone through their struggles whether it be nutrition exercise and mobility ... my favorite class is the 5:30 AM but she has multiple classes and it is a super fun and exciting environment, I give five stars....
Fantastic experience: I walked into this gym a couple months ago scared out of mind because I had no idea what I was getting myself into. However, that quickly changed as I was welcomed with open arms and smiles and helped every step of the way. The staff are so friendly, the owner is incredible, and most importantly I feel more confident, strong, and healthy. I highly recommend Sideyard Training and encourage everyone to JUST TRY IT!
Fantastic experience: Wow! AMAZING WORKOUTS! Sharene is superwoman with skills! She runs a tight program with amazing variety and targets every single muscle in your body...even ones you didn't know you had :o . Her staff is awesome and every single one of them care about your safety and success. The workout is tough and is adjusted to every skill level on the spot, the challenges are legit and the support is unlike any gym I have ever seen. Sharene and her staff are AMAZING! If you want to get in shape, stay that way and improve mentally & physically, Sideyard cannot be beat!
