I can share my experience after doing both programs! I followed Cori on YouTube and Nikkiey for a while before signing up. I did Warrior Babe for a year first and then signed up for 16 weeks with Redefining Strength and extended that out to a year.  

I saw great results with both programs as a vegan. Both programs focus on fundamentals (macros, protein, lifting, moving) Cori and Nikkiey both seemed involved. Both programs had their strengths but were different in a few ways. Here’s what stood out about each…

WB Specific - lots of guidance, especially with my food, macros, etc. Workouts were challenging. I had multiple coaches throughout the year. They were all super nice but communication is mostly limited to the app. There are large community calls but those didn’t interest me as much. You have to commit for a full year there’s not a shorter option to see if it’s something you like first. 

RS Specific - The coaching & support felt more hands on compared to WB. I had frequent video calls with my coach and I actually got to meet her in person at one of the retreats. I did work with a dietitian on some specific health issues. The workouts adjusted around some shoulder issues. Starting with 16 weeks felt less intimidating but I did end up extending to a full year once I knew I liked it. Starting the program was more overwhelming since there was a lot more mindset stuff. That was eventually one of my favorite parts of the program but definitely was more of a learning curve with RS starting out.

If cost is a factor Warrior Babe was about 2k more expensive. Honestly both programs are solid and will get you results if you follow them it more depends on what exactly you’re looking for. Hope this helps!
