    I have been going to Core Strong for a couple of months now. The classes are challenging and never routine. The coaches will suggest modifications if needed and push you when you need that too! Going to a new gym can be intimidating, but I can honestly say that I have felt welcome from day one. I really enjoy the comradery of the coaches and members. It may sound cliche but this is a gym family, they truly care about one another, not only at the gym but outside the gym as well. Everyone is encouraging and the accountability keeps me going back. My original goals were to get stronger and improve my balance and Iā€™m proud of the progress Iā€™m making.

    CORE Strong Fitness is hands down my favorite place to workout. I''''''''ve been a member for a little over 5 years and they keep finding ways to challenge me, encourage me, and cheer me on. The coaches create a welcoming space for all because fitness and health is for everyone.

    I absolutely love Core Strong Fitness. I started by doing the small group training for 6 weeks and was happy with the progress I made so I decided to continue with taking the group TRX classes.Jeremy and Hope are awesome coaches! They push you but keep you motivated and can easily provide modifications if you need them. You can tell that the staff are passionate about fitness and are very knowledgeable about anatomy, physiology, and kineseology. This is really helpful when explaining the exercises we're doing and why we're doing them. The other members are great too; friendly, welcoming, and encouraging. I'd recommend this gym to anyone and everyone wanting to feel better and get stronger.

    While my new milestone may not be celebratory for some, for me it is a major accomplishment! When O began my Core Strong journey in late June, I believed my ā€œwalkingā€ had strengthened me to fairly good health. Then I started to learn what my core is.... Thanks to Mark & Elyse encouraging me, I became determined to become strong!! Today I did the oblique plank (I think that is the right term). Was I as good as I will be soon? Not at all! But I am celebrating the success in my journey! I am 23 pounds lighter & many ā€œplanksā€ stronger! I also realized today that I am not anxiously checking the time clock to see how long I have to ā€œsurviveā€ before a break!! Again, small steps toward strong! Thank you new workout friends & coaches!! This life change is awesome!!!!

    Core Strong is truly awesome!! Itā€™s truly a place where you can own your workout!! Think itā€™s too hard? Modify. Next time youā€™ll modify less until before you know it, youā€™ll be lunging, planking & pressing with the best! Give it a try!! Youā€™ll be very glad you did!!

    Iā€™m so thankful that I got up & did the 6 am workout!! Busy life - more hectic than usual. You might even say ā€œhardā€. When the alarm went off at 4:30 I was tempted to roll over & sleep for another hour. Sinus headache, exhaustion & a busy schedule: skipping class would be justifiable, right? Wrong! After the workout I had a greater level of energy & my headache was better! Thanks, Mark Campbell, for a great class & for being an encourager toward ā€œstrongā€.

    I thought I was in fairly good shape - I could do a mean walk. Lol! I am learning that I have so many muscles Iā€™ve not utilized to support my frame (like probably NEVER).
