Had a couple mental issues with the food but got there. And every time I freaked out, Sara was so sweet that she helped me get back on track. Takes a lot of commitment.

Before I joined Grinders about 3 years ago I was bored and about to give up on my workouts…read more Grinders has THE BEST trainers, my fellow Grinders are family and the workouts are never the same but very effective always keeping me on my toes and my body sore(in a good way). There are many class times to choose from every day of the week so there is no reason not to make it in. Hands down the best decision I have ever made is to join Grinders and continue my membership. I look forward to class everyday and always feel so good when I leave! I highly recommend you coming in to try a free class. I am in the best shape of my life. You will not regret it!

If you're considering a place for your child or yourself this is it. Jordan and the team go above…read moreand beyond for every student but really go out of their way to make sure kids are excelling not just on the mat but in every aspect of life. Jordan is one of the best role models you could ask for your kiddo but quite honestly, every coach offers something so valuable for every kid. They not only teach the kids skills for self defense but put a focus on the human they are outside of the gym. He teach kids to be extraordinary not ordinary. This is the best investment you can make for your child, don't hesitate to enroll them here.

Went there with my husband in Jan and we did the 3 month thing for 300.Decided to do the 6 month…read moremembership because it ended up "being cheaper" only it wasn't because after the 6 months, we are continuing to be charged even after asking the owner to stop. Still being charged. It's 2 months past. Also found my supposed auto renewal agreement and it's not even my signature!! Not even close. There is also no follow up email reminding you your membership is about to end and you auto pay will begin. It's been a scam for us. Straight up just taking money from us after my requests to stop. Totally shady and unfortunate cause it was a cool workout when we were going. Just couldn't fit into our schedule. I've written to the owner with photos of the signature that's not mine and dates of contract. I'm hoping he reimburses us and does right by his customers,but as of this past week, still stealing from my bank. I'll keep you posted. If you do go here, make sure you check your bank statement for things like this. :(

Delanie, Steve and Kevin are very motivating and fun to work with. Do I wish they were open later on Saturday's? Maybe. But should I get my lazy butt out of bed and go work out earlier? Probably. I have been struggling to find a gym home for a while now, and I believe I finally found it. I feel great, look great, and am excited to continue here.
