Hannah Acosta is a Grass Valley lifetime local and Mom of three. She began her health journey in at over 200lbs in October of 2014. The change happened after her uncle lost is battle with high functioning depression, and a close friend, who'd had a stroke and was left half paralyzed, declared she was going to run the LongBeach Half Marathon. With that inspiration, and zero fitness background, Hannah signed up herself up for October 2015 long beach half, along with a series of mud runs to start her training. In June of 2015 joined CrossFit Pick Axe to kick her training up a notch. She loved it so much she became a CF-L1 soaked up every bit of knowledge she could, became there Kids coach, started up a balance program and eventually ended up buying it in May 2017. She ran the gym as the head coach till January 2020 deciding her vision of fitness and health needed room to expand and came to the Training Zone. She holds a Medical Assisting degree, a Tested CrossFit Level 2 cert. Burgner Weight lifting cert. As well as Anatomy & Physiology, and adaptive scaling. Hannah is the creator of the NorCal Longevity & Balance formerly known as Longevity Strong at Crossfit Pick Axe. This program was built on what she saw and learned as a Private in home Caregiver and Hospice Aid for 6 years. Thru specific strength and conditioning techniques you can prevent falls, build confidence, and give a higher quality of life to our active and aging communities. Falls are the number one reason first responders are called on the scene and it is her goal to prevent as many as possible. Fitness can start at any time and any age from 5-110 you just have to make the choice to do it and keep making that choice even when you don't feel like it. "I wish there had been something like this when I was younger, sports weren't my thing, and strength training was still a guys sport. It took an eating dissorder, post partum depression, anxiety, the loss of a beloved family member, and one friend having a life altering medical emergency for me to take my life into my own hands and stop being afraid of the possibilities outside of my comfort zone. It's my goal to encourage, support and train anyone who is ready! Be unapologetically you and 100% authentic no matter what!! Life is to beautiful and short to waste being anything other then your best you"
