Get Motivated from What others are saying about the K!

Seriously a breath of fresh air. Great facility, good strength training equipment, good cardio selection and well maintained. The staff is amazing. I’m active duty military on holiday leave, the front desk clerk immediately brought me in, made my wife and I feel at home and welcome. Set me up with a free membership and told me it was a priority for their company to take care of our military members and families. I haven’t been treated this well anywhere else I’ve been in the United States. I will never go anywhere else while I’m home again. Thank you so much K4 Fitness!

I was looking for a local gym with a trainer, friendly atmosphere, great equipment to loose some late 30’s weight. Boy did I find it!!!! Jeremiah, the owner is a super friendly guy that welcomed me my first day, showed me around and gave me the straight forward info I wanted/needed. Easy access and really nice equipment make a gym but you can tell they really have a nice local family feel. I would recommend this place to anyone!!!

Shaun S.
