About
I am located in Southfield, MI. WHAT WE DO: With over 15 years of experience, I provide safe and effective personal training and nutrition planning in a comfortable, encouraging atmosphere. Instead of simply telling you what to do, I show you what your body is capable of. I use a multifaceted approach to exercise, implementing free weights, body weight, TRX, kickboxing, circuit training, cardiovascular exercise, and more. I am able to compensate for any limitations you may have, ensuring the best results possible and a great workout every session. I am equipped to guide you through a complete body transformation; be it weight loss, gaining lean mass, sports conditioning, pre or post-op exercise, improved balance and flexibility, pre/post natal, nutrition planning, or as a reliant motivator to hold you accountable! WHAT SETS US APART: I was a Medical Assistant prior to becoming a trainer which has enhanced my abilities. I know the human body extremely well and am always eager to educate clients on what they are doing and why. I am also a certified stretch practitioner!

Shannon is absolutely awesome!! She taught me a lot of new workouts that I can do at the gym and at home with (and without) the equipment I already have so it’s been pretty cool having that versatility with the same impact no matter the location. She’s so nice, always flexible, and pushed me further than I thought I could go and I’m so proud of myself and I’m so thankful to her for her patience with me the whole way through. Her stretching techniques also left me feeling so much better after every single session so I highly recommend her to be a helper on your fitness journey too!!!

Shannon is a top notch trainer. She’s constantly challenging me, her knowledgeable of the muscles and the way she knows form when lifting weights is really helping my strength. I would hire her again in a heartbeat!

I hired Shannon to train for 3 months before my wedding. She is nice, motivating, funny, and flexible! We did part online, part in-person. My goal was to develop a mind body connection with my abs, strengthen them, and generally look trimmer/leaner for the wedding. Shannon has helped me do all of that! She provided calculated steps to strengthen my abs and avoid my chronic problem of my hip flexors taking over. She helped me with my form in all exercises (left knee hated squats until Shannon came along!). She is a wealth of knowledge physically and nutritionally! She took a close look at my diet and suggested do-able changes to help me reduce body fat percentage. I would love to work with her again in the future.

Thanks so much for the thoughtful review, Sam. I'm so glad you are happy with your results. I'm positive you were a beautiful bride, but more importantly, more confident. I would love to work with you again as well!

I started working out with Shannon when she taught a group kickboxing class that I attended. The group was typically 5 people or less. Shannon made a point to make everyone feel comfortable. She gave us individualized modifications to exercises, personal tips, motivation and nutrition information. She actually made me WANT to work out! I have used her for personal training as well. Her exercises and meal plans are very personalized to what you need. She really makes it a point to get to know your likes/dislikes and what motivates you to succeed. I would highly reccommend her!!

The space is not very friendly. It is located in a cabinet making facility. We had to move boards to access the suite the first time. No signage. There are showers but I do not believe they are cleaned frequently. There was a dirty towel in the shower for all 3 sessions. Mostly, Flexibility regarding cancellation policy is too rigid. 4.0 Fitness requires you pre-pay for the entire month and if you miss a class, NO REFUND. The policy is not designed to sustain a long-term engagement. Buyer beware; I ended up pre-paying for almost 2 months because we started mid-month. 3 Sessions ended up costing me $675.00. NO REFUNDS. I cancelled because I was uncomfortable after the conversation. Most expensive personal trainer ever.

This is surprising and unnecessary. I don’t appreciate you marring my perfect 5-star rating for more than 15 years straight. I have been told many times how welcoming and cozy my space is. The shower and towels are cleaned frequently. The one left in the shower room was for wiping up the wet floor after showers. But it also gets washed. As far as your refund, you signed a contract that explicitly states I do not issue refunds unless you are injured or ill. I asked you to read it carefully. No, simply deciding to not continue does not warrant a refund. And I am not expensive. Personal training is a luxury and the price is reflected. I have a degree is health science and exercise physiology, almost 16 years experience, and 3 certifications. My price is based on that. If you can’t afford it, then hire a less qualified trainer. Also, as we discussed, I have a 24-hour cancellation policy in place like any other business. I have to abide by that as best as I can to run my business most efficiently. This is my livelihood. You should respect my time. AND, you forgot what time we were meeting for a session then wanted to reschedule when I was 10 minutes away. I graciously rescheduled you to the next day and you canceled that session outside of 24-hours! All of which I didn’t charge you for! So to say I don’t have flexibility in my policy is baffling. Good luck to you.
