If you’re thinking of working with Kari, do it—you’ll bfe happy you did! She is the perfect combination of cheerleader, taskmaster and educator. Not only have I gotten stronger and more confident with lifting weights, I have also learned so much about diet and nutrition and the impacts of menopause on women’s health.

I came to Kari as scorched earth. I was struggling in my marriage, overworking myself, and spreading myself too thin. Through workouts, nutrition, affirmations, meditation, breathing exercises and stretching, Kari reshaped me physically and mentally. By taking care of myself through body and mind, I could reclaim my life through tiny shifts and habits.

Eight weeks into Strong Body Strong Mind my body composition has changed in the best possible ways, my mobility feels incredible, and I’ve PR’d multiple 3RM lifts. I genuinely feel better than I have in years. Strong Body Strong Mind’s programming is the real deal.
