He is an energetic, outgoing person, who is very detail orientated. He’s extremely reliable and always on time (if not early). People would have a hard time believing that Will is super lazy at home. All he wants to do is play on his PlayStation 4, watch track and field videos and eat candy!

Lynne has her NASM-CPT certification as well as a Spartan SGX Coach, NASM MMA Conditioning Specialist, NASM Fitness Nutrition Specialist and TRX Trainer. She takes great pride in being able to take her natural attention to detail to designing workouts, whether boxing or Spartan or adult lifting to help clients achieve what matters to them.
