Sara Maple

Welcome our New Trainer - Sara Maple

 Hi! My name is Sara Maple and I am an ACSM certified personal trainer with 11 years of experience. My family and I are new to the Magnolia area but it feels like home already. I am a wife and a mother of two energetic little boys. As a trainer, I work with clients of all ages with a wide variety of goals, lifestyles, injuries, and skill levels. I have led group fitness classes, started and maintained my own bootcamp, and utilized both partner and 1-on-1 training formats. I strive to provide my clients an overall better quality of life by focusing on improving strength, flexibility, and endurance. In addition, to these three cornerstones, I further support clients with nutritional guidance, accountability, and my Sara Maple Fitness App. My app is a super convenient, user-friendly way to receive workouts, complete with video demonstrations, to facilitate training on your own if/when in-person sessions are not possible. Ultimately, my goal is teach you how to safely train in order to have a healthy and active lifestyle. I would love to personalize a workout program for you!

Allison Haenel

I’m a Christian, wife, mother, daughter, sister, and friend. I have experienced many of life’s ups and downs and I have found that by God’s grace and putting positive or negative energy into a good workout can keep a person going. I’ve loved workouts of all kinds for as long as I can remember. Weight training, kick boxing, swimming, running, zumba, pilates, yoga and piyo have all been a part of my routine at some point throughout my life. I have a passion for health and fitness and earned a fitness instructor certification as a Bootcamp Instructor and have begun the journey of becoming a personal trainer. It is my desire to encourage all those I am blessed to work with, to become the best version of themselves.
