This program has been awesome! So flexible and easy to follow the instructions on how to do the exercises! Kaytlin is an amazing trainer, I love her way of teaching the exercises, nutrition. But most importantly she’s very encouraging, attentive, and supportive! I would and have highly recommended Kaytlin to train anyone!

Thatcher
"Before this challenge I felt stuck and a bit unmotivated. Now I’m feeling much stronger, more confident, and comfortable with my decision making. The confidence to walk around the gym knowing I belong there and had a great plan to follow. I wasn’t sure what an 8lb loss would look like or be big enough to shine in my pictures however this time I could visibly see all the parts of me that were changing not just physically but also mentally."
JameyLee (Down 8lbs -6 Week Challenge))
"I lost 8 pounds, and was able to increase the amount of weight I lifted each week. By focusing on healthy eating, and following the weight lifting program, I see a big improvement in my overall health."
Bardell (Down 9lbs -6 Week Challenge)
"I can’t even begin to describe how exciting it felt to truly commit to myself and see real change in just six weeks. Pushing myself, staying consistent, and watching my body transform has been incredibly empowering. For the first time in a long time, I felt in control again—of my choices, my habits, and my mindset. That sense of discipline and confidence has been just as rewarding as the physical results."
Lisa (Down 5lbs -6 Week Challenge)
