As a past over-exerciser, I felt compelled to make up for the calories I splurged on and struggled with a sense of lost control if I didn’t work out. My breaking point came when a serious injury forced me to reframe my relationship with myself, food, movement, and my body.

Fit By Amanda was inspired by the frustration and exhaustion that women feel in the gym, their homes, and their minds.

Through that experience, I regained my confidence in my body and my self-worth, gave myself permission to eat tortillas, rice, and ice cream, and learned to strength train more efficiently with less time and that gave me results I had been punishing myself for.

I began coaching as a passionate hobby that quickly turned into a second-life career. However, I was disappointed in the lack of transparent information and nuance pitched to you for your solutions. I know what it’s like to battle yourself, to be nervous for what was to come during your pregnancy and postpartum, and how it was challenging to just eat and enjoy your food.

Not only that, I know the best way to lose fat, get stronger, and see the body composition changes you’re looking for your lifetime, not just this month.

I supply honest, realistic guidance during significant life stages, and I aim to redefine what it means to truly feel at home in your body. I communicate and share simple adjustments to fit your lifestyle, without the overwhelm of products, hour-long sessions, or revamped pantries.
