Billy Lewis

Core Fitness - Billy
"I motivate not intimidate"

Billy has had a personal passion for body building since he was 16 years old, and is an ISSA Certified Fitness Trainer. He was once at a max size of 265lbs with 15% body fat prior to tearing off his right bicep. After two years of recovery, he found a style of interval training that he enjoyed and it was tweaked to the fullest while working at Drench.

Billy truly enjoys the clients in every class, seeing how far they will push themselves when asked. He loves to bring something new to each and every workout to keep clients wondering what will happen next.

Outside of CORE, Billy has been in the mortgage industry for the past 17 years helping people purchase and refinance their residential mortgage needs.

Favorite quote: "God grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference."



Kat Musni

Core Fitness - Kat
About three years back, Kat fell in love with fitness after completing a Jillian Michaels DVD workout. She couldn't get enough of learning different and more challenging exercises, playing around with many fitness tools such as kettle bells, UGI balls, and Equalizers, while also making use of more accessible objects like park benches and stairs.

With the influence of her kickboxing instructor at UW-Milwaukee, Kat realized she, too wanted to help others become healthier and stronger.

Having fun and exercising go hand-in-hand and Kat wants to inspire others to maintain this happy and healthy mind-set.

Kat has taught classes such as boot camp, butt and gut, and is now a kickboxing and boxing instructor. She is a certified personal trainer through ACE.

Besides working out, Kat loves to stay active in other ways, like exploring forests, baking, and painting. She loves meeting new people and would love to help clients achieve their fitness goals.
