The groove of movement.
The groove of habit stacking.
The groove of non-negotiables.
The groove of being YOUR best self. Your groove.
This is a 6 week hypertrophy progressive overload plan developed with you in mind. LOVE the plan. STICK TO the plan. Adjust your macro preferences to customize to fat loss, muscle growth, or maintenance.

I loved this workout!! I had so much fun doing it an actually preferred the at home version! The last exercise was so different but I felt it more in my glutes than I feel with regular squats for some reason. In my small apartment gym, this workout was perfect!

Esther is an incredible fitness influencer I’ve been following for the last 2 years and this is the second program I’ve completed of hers in the last year, the guides and use of the app is very easy to use and navigate, the community section is one of the best parts as that helps keep everyone motivated and keeps the good vibes going! I love Solin as an app and will continue to use it as I have just bought my 3rd program of Esther’s! I always recommend this app to everyone I know when they ask me for fitness tips! :)

This is the second program I’ve completed from Esther and I absolutely love her and these programs!! It gets you so in touch with your mind and muscle and awakens muscles you should be using in your day to day life outside of the gym, the confidence it helps build with weights and with fitness is general is amazing. I’m so grateful for these programs and helping me wake up from the slump I was in. I can’t wait to keep going strong with this one and finish strong!! I will be doing more programs by Esther in my near future 🩷

I’m loving the lifting movements however a few of the core circuits are to harsh on my wrist so I’ve had to improvise/replace a movement.

Goal getter v.1 is my favorite workout program from Esther! I've been able to grow and I love that solin tracks my PRs and other stats. I love having a gameplan to follow and I love the compliments I'm starting to get on my physique after lots of consistent hard work!

This program helped me get back into the fitness lifestyle. The workouts could be done at home or at the gym, which is very helpful during the holiday season. I can't wait to do Esther's "Train Like Me" program. While the community is great, I wish we got more interactions with Esther, but it is a crazy season for everyone! Overall, I enjoyed this program and am excited to make the small decisions that lead to big changes, whether that's mentally or physically.

I have enjoyed the program so far. I like that some of the exercises are the same and some change up each week. The way the program is laid out has helped me maintain my workout schedule even when I don’t feel up to it. My plan is to restart when the current program done and use this schedule to help continue the progress I’ve made and build on it.

As I entered university, after over 12 years of playing basketball - I had no idea how to move my body if it was not on a court. Forget the ‘Freshman 15’ - think ‘Freshman 40’. My initial return to the gym was from a place of self loathing, as I was looking for a quick fix. As physical results take TIME, I realized that focusing on what my body can DO was more exciting than what it looked like. While physique goals are amazing, and only natural, my love for fitness outside of aesthetics continues to keep me going - everyday. Being strong, creative, and striving for longevity are values I hold close to my heart. I am so excited to help you transform your life.
