Natasha Lowe Osho MD, Board Certified OB/GYN, National Academy of Sports Medicine Certified Personal Trainer, and Pre and Postnatal Fitness Specialist, started Bump Fitness Club as a way to merge her two passions of women’s health and personal fitness.  “After beginning my own fitness journey, I quickly realized that I rarely saw pregnant women at the gym.  As an OB/GYN, I also frequently had to dispel misconceptions about exercise during pregnancy while seeing patients in the office.  I realized that pregnancy fitness is a void within the fitness industry that needed to be addressed.  I enrolled in Lifetime Academy and received my personal training certification through the National Academy of Sports Medicine.  The combination of my medical training and fitness training has allowed me to safely develop a program specifically tailored to the pregnant and postpartum woman.”

Sarah Mallen

Prenatal Yoga Instructor 

Sarah’s journey into yoga began in 2000 while majoring in Dance in college. With a lifetime passion for movement she jumped at the opportunity to try it out. Like many, what started as a want for physical benefits, quickly turned to a deep desire and need for the mental benefits that came along with it.

After 15 years of personal practice, Sarah pursued a 250 Hour multi-style yoga certification from Ulu Yoga in Koh Pha-ngan, Thailand in order to bring the benefits of her deepest passion to others.

I am so grateful to do what I love most in life, and look forward to seeing you on your mat every day!

Jess Dunn

Prenatal Yoga Instructor

Jess is a wife, mother of 2, and yoga teacher who started her yoga journey in 2016 while pregnant with her daughter. “I started taking prenatal yoga as a way to stay active during my pregnancy. It not only gave me the physical activity I was looking for, but provided emotional support, a deeper understanding and control over my own body, and a community of mom friends that I still keep in contact with to this day.” She began teaching in 2018 focusing on classes for expecting moms, postpartum moms, babies, and young children.
