"I have been doing the #IronTwinsStrong challenges for the last three years. Each month is like the excitement of opening a gift!


Sometimes it’s something I can easily do and sometimes it truly challenges me to get out of my comfort zone. Iron Twins makes the challenges fun,  supportive and builds a community of women who cheer for each other. 


It’s always surprising to see the strength and proficiency gained in a month's time by consistently doing daily reps of an exercise.


Glad to be a part of the Iron Twins Strong Community!"

"Feeling stronger, doing this together. No experience necessary, just show up and do the minutes. It doesn't take long in a day, but it brings me a long way, throughout the year!


I'm always looking forward to the challenges, keeping me pushing myself, even if I don't feel like it. There's always an answer or a little push, it becomes a part of my day."

- Renate Ritskes 🇳🇱


"My motto is 'nothing is impossible' and my goal is to one day, be able to do a handstand.


Found Iron Twins on Instagram and discovered their #IronTwinsStrong challenges to build and strengthen handstands with different exercises for every month.


Millions thanks to your hard-work and I appreciate being a part of your community to be a stronger ME."

- Santhi Kennås 🇸🇪


"Fitness is a personal journey and for each individual a road their own. Setting goals for oneself is an excellent way to grow and move on down that road. I have found the monthly challenges set by Irontwins Fitness have not only forced me out of my comfort zone but proven to me exactly what I am truly capable of doing. First, they do the challenge with you so you have built in teammates. Second, they make sure your form is correct and always offer tips and pointers to help you along the way. Recently, during a 30 day headstand challenge, I was able to go from not being confident to try one on Day 1 to successfully completing the headstand and hold by Day 30 - with proper form due to the guidance and training by Irontwins Fitness. Support like this is priceless and they do it with a smile, humor and grace. I am proud to be a member of their challenge team and look forward to new adventures every month. Stronger every day in mind, body and soul."

- Marie 🇺🇸
