"The 112 mile bike went well! I felt good the entire time. The 5 mile run following felt good too. The first mile took me time to get my HR down, but after that I felt like I could go longer. I didn't have a sloshy tummy! So happy about that!

I contacted Alex while training for my 2nd Ironman. I noticed I was running out of energy while training and not recovering that well. My nutrition coach, Hanna, significantly changed how I was fueling and kept in contact to make sure it was working. We made many changes during my training period. I finished the IM and never felt out of energy. Very positive experience.

"Hanna, carb-loading is AMAZINGGG! I ran my 13 miler 45-60 seconds per mile faster than I intended and had plenty of energy left to push up the hills that were crushing me last weekend at the same point in my run. Like I just felt good the whole time. I feel INCREDIBLE!"

"I just finished my race!! I put into practice the fueling... holy crap it made all the difference and I could tell!!! The course was hilly and I didn't' feel like death!"

"Duuuuudddeee... BEST RUN EVER!! I felt strong, plenty of energy and no gut issues! Today was a 30 min temp run and I never thought 8:35 pace could feel so easy. Major confidence boost and I still have energy for the rest of the day."

"I am so happy that I chose you to help me through this. Had I tried this alone, I would be frustrated and wouldn't see results because I would be changing my approach all the time." 

"I nailed the nutrition and set me up for a fantastic run in the heat and hills. 70.3 PR for me!"

"I have never felt so strong running in a triathlon. I sprinted the last mile of the 70.3!"

"I had an amazing swim workout yesterday afternoon, and was able to turn around and do a near perfect negative split long run this morning. I actually stuck to a fueling plan before and after. I am so excited!"

"I legit feel the strongest I have in forever while running! I am eating more protein and I am actually putting on muscle mass which is exciting."

"So, for years, anytime I've done training, even short stuff, I've gotten super bad headaches. But, I haven't had a headache related to exercise since starting with you. It was so predictable and I could feel terrible all day and even to the next day. I've had two days of hard workouts and no headaches. This never ever would have been the case previously. It's clearly nutrition related. Thank you for everything.

I've been thinking about how without you I would've been under fueling and restricting on these days because I would have though I could lose weight that way. I'm not thinking that way anymore and I have thought that way since the 7th grade. Thank you. This might sound dramatic, but you have been life changing."

"I sure can't think you enough!! I know that I'm not where I was hoping to be by race day, but my overall feel is so much better.

Had I not signed up with you, I wouldn't have a chance at this race. Ever. I have learned so much about health in general for what I love to do. Thank you!!"

"Tried on a dress that I bought in April thinking it would fit… it was tight.  Hubby said to try it on again today (June).  Uh, it was loose!  Starting to feel the changes in body composition right now."  

"And all the keto and extreme weight loss peeps that lost big in the new year have started to put the weight back on. Not great for them, but really makes me happy for the long, slow progress."

"Alex!!! I did it! 13.1 miles, slightly faster time and more importantly I felt good. Last time, I barely dragged myself the last three miles.

Now, I want to train more and get stronger and faster. But I feel like working with you has made such a giant difference in just how I feel and has given me the energy to really push myself to the next level. Thank you!!! Working with you is amazing!!!"

I went from a burnt out athlete in 2021 who feared carbs to a thriving triathlete who focused on fueling! I was able to greatly improve my overall fitness because I was eating enough and fueling my workouts properly. Hanna genuinely cared about my progress and gave tons of great feedback throughout the process.

"It's been a really interesting six weeks so far. I think I expected to lose a lot of weight, but it's turning out to be a bit different. I have lost some weight, but the big difference has been the impact on training.

I said to you two weeks ago that I was feeling stronger, but this week I have noticed that even more. Bike watts are matching what I'd normally have when peaking later in the year. This is a good sign for later on! Running too has been better."

"Knowing it's only been just under a month since we started working together, but WOW! My last two weeks of workouts on the bike were tough, but with the plan and understanding from the last call, I'm absolutely smashing these 1.5+ workouts! Can't wait to see what the next few months will produce! Let's go! Thanks again!" 

"Race report! 115 degrees on my Garmin, 109 miles and zero cramps, not a single cramp! Nutrition and hydration plan was spot on. Thank you so much, really appreciate it!"

The ALN nutrition coaching program has helped me become a better athlete, and it helped me achieve goals that I never thought possible, like completing a 70.3 Ironman or a full marathon.

I've had the privilege and joy to work with Alex. Returning to marathon training was rough with pandemic life, and I knew I needed help if I was going to not just get through Chicago and Philly, but finish them feeling good. I finally made the leap {to work with Alex}, and I'm so glad I did. 

I saw major differences. I had more energy during the day. I was able to run strong in my workouts and while coaching, and I FELT great. Thank you, Alex, for everything! For anyone looking for some guidance, I could not recommend Alex more. She is a true pleasure to work with.

"Alex, I need you to know how much your nutrition advice has positively influenced my athletic goals. My performance at the gym and during my workouts is at an all-time-high and I'm using weights in workouts that I would be struggling with just a few months ago."

-Roni

When I started with Alex, I was famished ALL THE TIME. I was caught in the cycle of under-eating during the day, then craving sweets like mad in the evenings and often overindulging.

Following Alex's fueling guidance for my long runs has been LIFE CHANGING. I feel strong the whole time with no dips in energy. I finish feeling energized, not depleted and tired all day. I can go out and do another long run the next day with no energy issues. I honestly cannot believe how much I suffered unnecessarily before. Thank you, Alex!

associate dietitian nutrition coach

I'm Mary, a registered dietitian and a certified personal trainer. I have been fortunate to work in clinical and wellness nutrition, in addition to working with athletes. 

I've been a long-standing distance runner after realizing the only part about softball I enjoyed was running the bases. I was a 3-time All-American in cross country and track and field at the University of Wisconsin-Eau Clare. I ran in the 2020 Houston Marathon in 2:44 and qualified and completed in the 2020 US Olympic Marathon trials.

You can find me chasing after my two little girls when I am not running or working. I also enjoy spending time perfecting sourdough recipes, cake decorating, reading for pleasure, biking, hiking, and pretty much anything outdoors. I embrace an all-foods-fit approach to nutrition and am overwhelmingly passionate about helping athletes fuel for training and life.

I'm Hanna, I am a registered dietitian and a certified personal training with certifications in corrective exercise specialist.

I'm a two-time All-American collegiate athlete in cross country and track from the Univ. of Wisconsin.

I have successfully competed in numerous triathlons and road races, including an overall female amateur win at Ironman Canada 70.3, 2nd place finish at Ironman Wisconsin (finish time of 10:08) and 13th overall female amateur finish at the Ironman World Championships in Kona, Hawaii (with a finish time of 9:55). 

I live in Minnesota with my husband, and when I'm not running or working, I enjoy playing in the kitchen dreaming up new recipes, diving into a good book, and helping fellow athletes follow and achieve their dreams!

Frequently Asked Questions

Do you accept insurance as payment?

We do not accept payment through health insurance at this time. We take payment via credit or debit card through our online coaching platform, Practice Better. 

How do we communicate with each other?

Between bi-weekly check-in Zoom calls, we use an online coaching platform, Practice Better, for you to use the chat messaging and journaling/tracking features to communicate with your coach. We are available to answer questions, send videos and offer any additional support needed through this platform. 

We do not offer meal plans as we work individually with clients to be able to create their own sustainable, healthy eating pattern through meals and snacks.

Macro tracking is something that we may offer temporarily in specific situations when it's a good fit for the client, but eventually we will work to towards behavior-based changes. The end goal is always for you not to have to constantly track everything that you eat and drink in order to reach and maintain your goals.  

Do you offer meal plans and macro tracking?

How long is your coaching program? 

We are all about transformations with our clients and only offer on-going coaching. There is a  minimum commitment of 3 months, but our most successful clients are with us anywhere from 6-12 months.

Do you do weight loss coaching?

We don't do rapid weight loss or weight-only goals. Setting realistic body composition goals can certainly be a part of your journey. Our top priority above all else is your well being and supporting your body as you progress through your training and events. 

A registered dietitian nutritionist has the the highest level of nutrition counseling education.

Only a registered dietitian nutritionist (RD or RDN) has completed multiple years of extensive education and training established by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).

In addition to holding a bachelor's degree, a registered dietitian nutritionist must fulfill a specially designed, accredited nutrition curriculum, get accepted into and then complete an extensive supervised internship program of practice - typically 1200 hours - and successfully pass the 3-hour rigorous registration exam.

What's more, roughly half of all RDs and RDNs hold graduate degrees and additional certifications in specialty areas.
