CrossFit Certified Level 1

I have always been interested in fitness on some level. When I was 15 I taught water aerobics to the moms at the pool club and I probably took enough step classes in my young life to step my way around the globe. I remember “Sweatin to the Oldies” in my parents living room and desperately wanting to look like Jane Fonda in my leg warmers.

It wasn’t until I moved to Baltimore and met my neighbor and new “box” owner, Lauren Closic, that I was introduced to Crossfit. I was immediately hooked. After birthing 4 children in 5 years, I never expected to see an ab muscle again or to do an unassisted pull up or to love burpees, but thanks the wonderful coaches I have had the pleasure of working with at Arenal, I have achieved many unexpected goals.

After about a year and a half of cross fitting, I received my Level 1 certification and am looking forward to working in this field for many years to come. I hope that I can encourage others to be brave and jump in with two feet, because they will not regret it.
