BWS transformations regularly make headlines

BWS transformations

regularly make headlines

romeo

From 25% to 9% body fat.
I became my own personal trainer because of the knowledge I acquired from reading every word of the program. I still read it up to this day.

Eshan

Reached 10% body fat & gained 10 lbs muscle.
I started going to the gym with no knowledge on what to do. After a few months, I stumbled upon BWS and I knew I wouldn’t be disappointed because everything was backed by science and facts. I look and feel like a different person now.

Danielle

Leanest and strongest she’s ever been.
I’m happy that I don’t feel like I’m starving anymore. I learned how to eat the foods I love, feel full, and still lose weight.

Justin

The program helped me rebuild the confidence, the love, and the self-respect I needed to have for me and mentally getting to the point where I needed to be.

Michael

What made BWS stand out was the amount of information they provide and the lengths they go to ensure success for its members. The program says these are the exercises, but this is why it works, this is how it works and these are the sources and the science.

Josh

I can see definition in places I’ve never seen before. Even with exercising at home, I have crushed my fitness goals.
