Philosophy on Exercise and Well-Being

Kas was born and raised in Southern California and moved to Illinois when she was 23 years old.  Kas grew up as a dancer and cheerleader, but was never heavily involved in other physical activities or sports.  After years of weight gain and personal struggle, she began her fitness journey to lose 65 pounds.

Kas began taking group exercise classes and quickly fell in love with learning more about what her body was capable of.  It wasn’t until her first yoga class that her interests turned into a passion.  Kas felt better than ever after incorporating a regular yoga practice into her life and quickly found the benefits of working out at the gym.  Kas completed her first yoga certification program in 2013. As Kas began to make new friends at the gym, she found that a common problem athletes faced was muscle soreness and injury and began instructing yoga and functional stretches to her friends and found they had a quicker recovery from future injuries.

Kas continues to find passion in helping others incorporate yoga practice into their daily and weekly athletic training routines.
