“I had back surgery a year ago and had led a sedentary life for more than 10 years. I knew I needed to lose weight, but didn’t want to injure my back again. Luckily I found Meraki CrossFit and owner Amy Posadas, who is a physical therapist. In 3 short months I’ve lost 30 pounds, and learned so much from Amy and all the coaches. Everyone is super friendly and encouraging. I cannot recommend Meraki CrossFit enough!”

“I have been suffering with lower back pain since I was in my early 20’s. Meraki CF had given me the knowledge and tools to help strengthen my lower back. I am so thankful that the coaches give me modified workouts to still be active without being in pain or hurting myself. I also love the community of people and they motivate me everyday.”

~ Jess Gonzalez, Member since 2018

“Meraki is a great place to workout. They have great classes, coaches, and athletes who push me to do better every
workout. They have all helped me get back shape after I got out of the military. The coaches make sure everyone is scaled appropriately for the workouts to ensure everyone is safe, but get a good tough workout in at the same time.”
