Our Boise gym provides you with a Personal Trainer and Nutrition Coach who are passionate about health and fitness and certified in the tools to help you meet your goals.  Whether you’re an Average Joe or Athletic Pro, our Boise-Grown, Family-Owned and Operated Health Club is ready to guide your efforts towards success.

Jack City Fitness provides a Partnership. Not a Membership.

Have you been a member of a gym before?  We hate to break it to you, but most membership gyms don’t care about your results or how often you workout. In fact, they plan on more than half of their members not using the facility. Recent research performed by Statistic Brain found that 67% of people that have gym memberships do NOT use them.   We don’t want you to become a part of that percentage!

At Jack City Fitness, we offer a Partnership where you are held accountable for achieving your health and fitness goals. We’ve found that this level of accountability ensures the results you desire. We’re proud to be the #1 Result-Driven Fitness Center in Boise!
