Lena Sundberg

Lena Sundberg: I started practicing yoga in 2007, when I was pregnant with my
first child. I had always been an avid exerciser doing various cardio, stretching,
weight training and volleyball. So naturally my first yoga class was at the gym. It
was this class that I met my first teacher who shared her enthusiasm, skill and
knowledge of yoga. I am so grateful she taught the importance of breath, proper
alignment and for the many adjustments during my practice. I learned not to
“muscle” into poses but to breathe into it. For it is more important to have proper
alignment than to force the pose and compromise the integrity of the asana. For
me, yoga is physically challenging and mentally soothing. The linking of breath to
movement and mind with body leads me to an inner calmness. It is meditation in
motion. Yoga has made physically and mentally stronger. It has taught me to
accept what is, enjoy what is now, breath through what is difficult and most
importantly, contentment (santosha). These are the life tools we all need to find
happiness and balance in our demanding and chaotic lives. And I wish to share
this with others.

I enjoy using my thorough understanding of anatomy and movement analysis to customize training sessions and fitness classes, honing in on individual needs.  I’ve always been involved in athletics, but it wasn't until I started weight training and incorporating interval training into my activities that fitness became a passion.

Over the past 7 years, I have been exposed to many facets of the fitness industry. My Certifications include: ISSA Certified Fitness Trainer, Corrective Exercise Specialist, Beachbody P90X and Insanity Instructor, Senior Fitness Specialist, Postural Re-education, Red Cross CPR/AED/First Aide and Surfset Tier 1 Trainer.
