I absolutely loved this challenge! It help keep me on track and I love how it showed the progress I was making. I also loved the videos of each exercise . I would watch a video before a I would start the next workout to help make sure I was using proper form . The last thing I loved about this was the community. The community was so uplifting and I loved the cheering of each other on. I really excited for the next challenge and can’t wait to get started on it!

This was my second challenge with Erin. I have tried so many others and Erin’s challenges are the only ones that I feel really give you the progress you’re looking for. Each of the workouts are curated perfectly! The access to the community for support and motivation is also a huge component that I enjoy. The past 6 weeks were challenging but also so rewarding and I will keep doing challenges with Erin as long as she keeps doing them!

I loved how simple this whole process was. Normally when starting a new program, it’s easy to give up in the beginning due to them being confusing and very overwhelming. This made me feel at ease and very motivated. I wasn’t thrown too much information or overflown with unnecessary information. The workouts were very strict and easy to understand. The videos added to it make it easy to figure out, even without weights. I loved that Erin would comment back on things in the community. It made me feel like she was really there to help and not just make money off of the program. It was really appreciated, even when we knew she was really having life thrown at her. ❤️

This was my first challenge and I was so pleasantly surprised by the quality of the home workouts. My ONLY recommendation to make it better would be to pair the home with gym exercises so if we have a barbell, squat rack, or whatever is needed for gym version we could sub them in. For example if goblet squat is a front squat in gym version, note that so if I have squat rack I could do front squat versus goblet (more weight available to load on BB versus limited DB weights). This probably wouldn't affect many, but I would love to see it personally. I am so grateful to have rediscovered my love for lifting weights thru this challenge, and have already signed up for the next!

The workouts are well structured and if you follow them i promise you will see changes in yourself and your body!

I really enjoyed the splits! I would’ve liked 1-2 chest exercises in there just to hit all muscle groups. I only had a few glitches with the app but overall I liked it and the tracking feature along with the section where you are able to keep notes. I know some people were looking for a nutrition portion/ macros - I was not needing macro help but I do believe one of the admins did say they would go over it and I don’t think they ever did. Not sure if it was included or not. Overall I loved it and I have recommended it to all of my friends! My body recomp was HUGE. I will be participating in future challenges for sure!!!

I don't even know where to start. This was the second challenge I've signed up for; the first one I couldn't complete due to mental health issues. So, I signed up for the summer challenge determined to do my best. Over these 8 weeks, I experienced many ups and downs and often felt like giving up, but with a lot of effort, I finished the summer challenge feeling like a completely different person. Everything improved—my self-esteem, energy, strength—and most importantly, my mental health. I feel like I can do ANYTHING.

So inspired by Erin and this program. As someone who trains consistently, even I was having a hard time seeing the results I wanted at first. This challenge really helped me get focused on balance between my down time and my grind time. If I missed a day, I wouldn't chastise myself, simply make it up or modify to match the level of intensity I could handle each day. Making sure I was hitting my macros and getting proper rest was probably the most challenging part of the program due to my work schedule, but overall I was consistent for roughly 80% of the time. I did see results, and feel super strong this go around. Most importantly, I just feel good! Thanks a lot, Erin! Your programs have really given me something to show up for each week. I look forward to your next challenge!

This challenge was exactly what I needed to help keep me disciplined, motivated, and accountable. I have always had the mindset that I needed to be perfect to make progress but in reality I needed to just take intentional steps to progress. This challenge not only helped me lose inches, and gain strength physically, but helped me shift my mindset into a positive long term direction. The workouts being grouped into phases made it much easier to stay consistent and learn proper movement and techniques to maintain safety, but they also did not take hours and were very realistic for me as busy working mom. The accountability group was fire and the community is incredible.

You do the work but she provided a framework that is so well planned. Your strength increases week over week and I saw changes in my body that I have worked years to see.

I have done 3 challenges with Erin now! It has always been a struggle for me to have a consistent gym routine… but this challenge has kept me on point!! The way it is structured makes it so that the workouts are enjoyable and challenging where I know I’m not just doing random movements, it’s well thought out. I have also seen the most difference in my body by doing these challenges and FEEL different in the best way possible physically and mentally. The Facebook group is one of the best things that comes with this challenge, it is so motivating and uplifting. Everyone in that group has always been amazing and supportive and you create friends through it! The admins are also amazing, shout-out to Erin and Fran. They’re always responsive. I will be signing up for every challenge to come. I can’t imagine not doing one now! It is truly one of the best decisions I have ever made. If you’re debating on taking that leap of faith, just do it, you won’t regret it!

Her programs have taught me so much! :-) Lifting has become a lifestyle for me now!

This was my first time doing Erin’s program, I decided to do it to get me out of my slump after being in school and it did exactly that! It forced me to try new exercises and machines that I always avoided and have come to love some of them like the chest press and rack pulls!!! I love the community that it brings and that everyone is there for you!! 10/10 highly recommend!!!

This was my first challenge with Erin and let me tell you, it truly changed my life!! I have struggled with losing weight and feeling confident in my body for the last 3 years and was at my whits end with what to do. I decided to take a leap of faith and join this challenge and over the 8 weeks, I lost 15lbs and gained so much confidence back. I feel better about going out with my friends or wearing a slightly cropped top now, instead of just baggy oversized clothes. If you are on the fence about joining one of her challenges, I promise you it is so worth it. The community and advice you receive are truly unmatched! I am excited to see what the next challenge brings!!

I absolutely love these challenges. I came across Erin august of 2023 and decided to give it a go. I was stuck in my fitness routine and not seeing results. After the first challenge I had amazing results! I stuck to it all, the workouts and food. Another positive about these challenges is the community she had created! I’ve never been in a challenge group before with such supportive women. On my days I feel less than motivated to do my workout I get a notification from the group and it pushes me. They are all so motivating and inspiring. I 100000% recommend erin and will be a lifer with her challenges

This was the first fitness challenge i've ever completed! I lost a total of 9 pounds and 1% body fat! I would highly recommend for anyone, especially if you're someone who is struggling with staying consistent with exercise. You won't just get a bunch of exercises and be on your own. You'll get to be part of a face book group with other members which keeps you motivated and on track. This challenge gives you a supportive fitness community, this doesn't feel like a competition instead it feels like a safe space. Everyone helps each other out with fitness and nutrition questions. I've already signed up for the next challenge! This is actually sorta addicting! 💪🏻💪🏻

Just finishing up my first challenge with Erin. My friend invited me to this challenge and I was skeptical because I’ve never finished a challenge yet. Most are 12 weeks so the 8 weeks length time was super appealing along with the ability to do a home or gym workout. even though I have been on and off with workouts for years I also really appreciated the video how to clips. This way I never had to guess on what was expected including good form reminders at my finger tips. I actually will finish this challenge and am really looking forward to the next 8 weeks.

I enjoy doing Erin’s challenge group. I won her first round back in 2023 and I’m now still Maintaining and building muscle I’ve never had before, i rejoined to keep myself consistent during big life changes. I find myself always scrolling through the face book and regaining the drive to care. I love that each time she does the challenge it changes so we can develop muscle in different areas of our bodies and confuse them. She’s extremely supportive and you would be crazy not to want to stay .

The Grind – 6 Week Challenge

I like that the meal plan has my calories and macros calculated. For me it is hard to know what to eat next. I purchased this to do with the 6-week grind challenge and so far it has been great. The one thing I would like is to have a grocery list and some meal prep recipes already added in the weekly schedule. Iam excited to see what the next 5-weeks of this meal plan will help me with my goals.

While I will say I loved this challenge, the people in the group, as well as the workouts and exercises provided, I feel as if some of the things advertised for the challenge are not true or things I wish were improved. First of all, there is not a true 1:1 messaging with Erin; you can tag her in comments in the Solin app of FB group, but there has not been a 1:1 form of messaging. There are incorrect videos for exercises provided, and they're not always fixed or corrected like it's stated they would be. And when tracking weight, you don't track in the app but rather there is a tracking sheet provided that you can print out and write on. Like I said, I love the past few challenges I've participated in but wish there was full transparency on the things offered or advertised as available.
