“This top secret pre-workout supplement has a proprietary blend so it’s the ultimate fat burner that will give you instant results!” 

I’ll take a wild guess that you’ve come across LOADS of these buzz words if you’ve looked for supplements before. Why do you see these everywhere? It’s easy to make a false promise!

Pre-Workout? That just means it’s loaded with stimulants that will send your heart rate through the roof.

Proprietary Blend? That means they don’t need to tell you what or how much of each ingredient is in the product! It’s a sexy-sounding word but it’s a way to hide ingredients

Scary? Definitely! Our focus is giving you supplements that will safely fuel your training and lifestyle without any of the gimmicks.

Hi, I’m Cori Lefkowith…

I’m the owner and founder of Redefining Strength. The reason I can get my clients great results is because I’ve been the idiot that has made every mistake and experimented…Even with ridiculous things. I’ve been stuck in that diet and deprive, binge, guilt, binge, try a new diet cycle.

I’ve ignored injuries and pushed through only to end up more injured. I’ve gained weight and lost weight. I’ve worked out hard and then slacked off because I’m so burnt out.

And because I’ve made all the mistakes, I now know what works. That’s why I can help you.

I realize that each person has unique needs and no two fitness journeys will look alike.

I realize you’re going to slip up. That mentally sometimes you’ll want to give up or start beating yourself up.

I realize you may even be scared to start something new and get outside your comfort zone.

That is why I create programs for real people that meet their individual needs.

I’m more than just a ton of certifications. My knowledge is from real world experience, dealing with real people just like you!

I look forward to helping you on your journey!
