About Lissa Stritesky and ASSIDUOUS FITNESS

The Story Behind Assiduous Fitness

My fitness journey started after having children when I found myself at my heaviest. I had always been active, but the struggle to lose weight felt overwhelming. Through strength training and proper nutrition, I lost 100 pounds—proving to myself that lasting change is possible.

That transformation fueled my passion for helping others. As a NASM-certified personal trainer and nutrition coach, I’ve spent the past 6 years helping clients lose weight, build strength, and create sustainable habits.

I founded Assiduous Fitness to provide personalized, results-driven coaching that fits into real life. My mission is simple: to help people take control of their health and build habits that last a lifetime!
