Feel SO GOOD you forget what it’s like to feel bad.

Stressed & Exhausted 24/7

This quote was pulled from a 2007 article by the American Psychological Association, which states 77% of people experience physical symptoms related to stress, including fatigue, headaches, digestive issues, and change in appetite. Since the original article was published, the amount of people dealing with extreme stress and exhaustion have skyrocketed.

“Stress in America continues to escalate and is affecting every aspect of people’s lives…”

  • “I loved how Marissa gave me such easy nutrition advice to follow within the first 10 minutes of our first phone call. She checked up on me weekly and helped me pace my workouts so that I was getting the most out of progressive overload. My weak point was nutrition, and honestly I was worried that the only way to lose excess fat was to go on a crazy restrictive diet, but I had all the control on what I ate. She showed me that that wasn’t the case, and after just 30 minutes on the phone, I felt more driven than ever to make a consistent change and work with Marissa long term. She gave me the tools to do what I needed to do. Who knew how yummy home-made protein bars could be! I knew things were working when when I was able to be in a calorie deficit and still eat the foods I love, all the while feeling leaner and stronger every week! She gave me the tools to make simple changes to my nutrition, but it was nothing extreme or restrictive. It was easier than I thought! Never did I feel like I was on a “diet” or like I was making a quick-fix. I made slow and steady progress and it was so worth it. 🙂 I lost 30 pounds in about 5 months and 4.5 inches off my waist! Fitting back into my old clothes.”

  • “Before Marissa’s program, I had a lack of motivation and structure. I didn’t have proper goals and didn’t know what to aim for. I just didn’t have enough knowledge to figure out how to solve my problems. I knew things were working when I started feeling stronger and more confident. Just overall saw my stamina improve. Now, life feels pretty good! I can see myself getting stronger and feeling better about myself. Small things like an improvement in posture, walking a lot without getting tired, etc. I stopped measuring weight and inches because I felt like I would always feel bad about myself if I didn’t see a certain type of number. I can say that my clothes fit better though!”

  • “The moment I realized that Marissa's program helped was when I started feeling stronger physically, mentally, and spiritually. Meeting her every week was something I truly enjoyed and it made me take time to actually care for myself. Heck, my therapist noticed a change that I was going through and now, my body feels stronger. I will say that another moment that made me truly realize that I picked a great trainer was the fact that even as I am working out now, she stayed, even though I was struggling with my “why”. That means a lot because it shows she’s patient and is willing to wait out to see that change.”

  • "Marissa is an amazing trainer who truly cares about her clients. I don’t know what I would have done without her. Before starting the program, I had a hard time losing excess belly fat and growing my glutes. I was worried about falling back into restrictive dieting and calorie counting. But Marissa’s nutrition approach transformed my way of thinking. I learned really important nutrition information that I wouldn’t have known otherwise. I’ve also found that her workouts are fun and rewarding! My mood changed dramatically when I stopped obsessing over my calorie deficit and focused on protein and weight lifting instead. I’m so much happier not thinking about calories every second. I focus on eating less processed food and more nutritional food, along with more protein. I also fell in love with weight lifting now that I’ve seen progress. I lost 2 inches off my waist too! Marissa always makes me feel empowered and excited about my progress! If you want someone who cares about their clients progress and how they’re feeling, she’s the one!"

    Madison C.

  • "Before Marissa’s program, I had low energy, low self esteem and I didn’t feel strong. I wanted to lose weight but also gain muscle, however I didn’t know how to do that. I felt unmotivated and unsure what to do. I never knew how to workout properly and Marissa just gave me so much direction and advice. She gave me modifications for exercises since I have many old injuries and allowed me to workout from home. She let me work at my own pace and cared about my goals. I just felt like Marissa truly cared about me and my goals and I appreciated that more than anything. She even answered the million questions I had and gave me resources so I could fully understand and research for myself. I noticed things working during the first week of doing her workouts and I just felt empowered and motivated and knew she’d be there supporting me every step of the way. Now I feel strong, I can carry more boxes and I feel more confident. I am also not feeling jealous of other people’s workout achievements and that is thanks to her video where she said that when I am feeling that way to tell myself “not the same” and that was some of the best advice. I also lost 5lbs in 8 weeks of her program and gained muscle!!!!"

  • "I started Marissa’s program to get into shape for my wedding! I kept saying I couldn’t do it on my own, and would push it off. I also noticed I had a weak back and dealt with a lot of pain in that area. Marissa held me accountable, and helped me learn I can do it. After a while, I felt stronger and noticed I didn’t need my husband to crack my back as much. Overall, I have way less back pain and can lift much heavier!"

    Leesha M.

  • "I started Marissa’s program because I didn’t know what workouts to do in the gym. The anxiety of not knowing made me not want to go. Her program helped because it was consistent, yet had variety in each workout and explained things very well. I realized the program was working when I was able to continually increase my weights without issue! Now, I am finally going to the gym consistently and am confident when I do. I feel so much stronger and even lost 2 inches off my waist!"

    Katie A.

  • "I was struggling with staying motivated and consistent prior to Marissa’s program. The most I could stick with working out regularly was 2 months at a time. I felt like I couldn’t hold myself accountable and like I wasn’t making much progress. This program was different than anything else I had tried because it really kept me consistent, and I never dreaded going into the workout. I realized things were really working when I started to move up in weights and got excited to go to the gym every day! I am no longer anxious to go to the gym, and I love the feeling of getting stronger and more capable!! As far as numeric wins…my body fat % went from 16.4 to 15.9, my waist went from 35 to 30in, and my butt went from 36 to 39in in 8 weeks!!"

    Sasha N.

  • "Marissa's program really helped me gain a healthier mindset about my fitness. I realized I was getting stronger, I was happier, and I was less negative about my own body when looking in the mirror. Even though I’m still working towards my goal “aesthetic” results, my time with her has made me fall in love again with more than just working out to change how my body looks…I want to workout now to get stronger and because it helps me de-stress. My life is a lot more positive now. When I look back, I realize that the months when I’ve been the least stressed have been when I got back into a workout schedule, so I’m definitely going to continue for all of the benefits in addition to the aesthetic ones."

    Julie S.

  • "When I discovered Marissa’s program, I was just finishing my third year of college and had picked up some unhealthy habits. I was really active in high school but did not have a good relationship with food. That caught up to me as I was much more stagnant at school, especially with late nights/all nighters, lots of snacking, and cafeteria food. I’ve tried cutting certain foods out, tried keto, and other restrictive measures and it made my relationship with food worse. It was hard doing research not knowing what was accurate information online. I was even more discouraged when things didn’t work and made me feel sick and down while trying them. The nutritional information Marissa provided helped me see food in a new way. It wasn’t restrictive and I saw changes right away. Other things I’ve tried made me feel sluggish, hungry, and lowered my mood. Within less than two weeks of this program I wasn’t bloated, I had energy to help carry me through the day, and it helped me start waking up earlier! And I’ve NEVER been a morning person. I realized her program was working when I was able to do certain exercises without modifications. And also when I stopped craving so many sweet and processed things! I’m now on my way to better scheduling and prioritizing my health. I’m also better able to identify and create nutrient dense meals which is a huge accomplishment! My relationship with food has never been better and it’s still improving!"

  • "I used to not really want to get out of bed, due to self consciousness, and lack of energy, but when I started to implement Marissa's advice into my life I was excited to get up and I began liking who I am. Now I eat better, have more energy to do things with my family, and I am starting to like the way I look."

    Brianna F.

  • "I struggled to figure out what to eat before working with Marissa and had the goal of increasing my caloric intake and gaining weight. I finally feel like I'm seeing the results I've been looking for and have become more energetic and less bloated!"

  • I found Marissa on TikTok and was intrigued to hear she was going to become a registered dietitian, because I needed one! I started doing online personal training with her because she seemed super knowledgeble and I felt like she'd be really easy to talk to. She was very receptive to things I said I did or didn't want, and once she became a dietitian I got started with her meal planning services! She is a great listener and always kept things super personalized and realistic. She never made me feel bad if I didn't hit a goal and I never felt like I was being lectured or talked down to like I had experienced with other coaches. I wanted to lose weight and build muscle, but I really also wanted to become more confident in my body AND in the gym, which has given me a lot of anxiety in the past. My biggest challenge with meal planning was setting aside the time I needed to eat healthfully and really plan everything out, as well as shifting my eating habits to more whole foods. I also hate doing dishes, so she gave me "one pan" meals which helped a ton. Once we started working together, I immediately felt a huge difference in my energy and my gym performance. I went down from 3 coffees a day to 1 small in a matter of 2 weeks. I also immediately felt less bloated and experienced surprisingly quick changes in my muscle development. Now after working with her for 5 months, I feel less stressed and anxious, and I feel SO good and so confident. I actually like going to the gym now. I also don't have nearly as many stomach issues. I lost 10lbs slowly and sustainably and built muscle. I no longer focus on JUST losing weight, I've accepted that slower weight loss is ideal and building muscle is so important too. I'm so happy with everything and this is the first time I've ever acknowledged that losing 1lb a week is right for me and this program has changed my mindset so much. I don't feel the guilt I used to experience with previous dieting attempts.

  • I like Marissas services because not only is she helping me be more comfortable in the gym and challenging me, but she’s also helping me be mindful about what’s going into my body and helping me understand a balance. She’s very supportive and wants nothing but the best for her clients.
