As Seen On

Why “No Memberships”?

All local gyms offer stone age memberships, but Jack City Fitness isn’t just any old health club. We’ve heard way too many tales of people signing up for a gym membership, getting off track, and abandoning their fitness routine altogether — while still paying a monthly gym bill. That makes us extremely sad — especially because some gyms actually bank on this happening. Beyond Gross. At our Fitness Facility, we strive to create positive and nourishing relationships with everybody who walks through our doors, not swindle people with cheap gym memberships. That’s why we scrapped the idea of memberships altogether and created a proprietary high quality custom service called a Partnership™. When you join our Jack City Family, we become Partners in health & fitness because after all, we’re in this together. We plan to be there when the going gets tough (no contracts or hidden fees), when you feel like quitting (custom build Partnerships™), or when you’ve lost motivation (full time Accountability Coach at your aid). Our Partners constantly get check in’s to make sure goals are being met, nutrition is on point, and measurements are being taken. We’ve got your back.

We’re also always adding new equipment to our facility—we like to keep up with the latest fitness trends. Wondering if we’re getting any new machines in, or how we handle our maintenance process?

What Makes Us Different From Other Gyms in Boise?

At Jack City Fitness, our priority is YOU.  We work hard to make sure all our athletes have the support they need to meet all their goals, whether that means designing a custom workout plan, working around unique schedules, or offering unending support and accountability to every person who walks through our doors. These athletes who grow and work with us are never considered “members”—what are we, some exclusive club? No way. At our Boise gym, athletes who sign up to train with us are thought of as equals. That’s why we call them Partners.  As a Partner, your needs take top priority. No two athletes have the same path, but everyone will receive the same outstanding support from our team. We keep our doors open 24 hours a day, 7 days a week, because it’s important to us that our space is convenient for you, no matter when your ideal “gym time” may be. Our Partners have full facility access before and after typical office hours, and with our fingerprint scanner “keys,” you can rest assured that the space is kept secure all night.


  • Do I have to be fit to fit in at Jack City Fitness?

    Of course not — movement is for everybody! At Jack City, we have no time for snobbery. We work with everyone, from a workout newbie to athletic champs. It doesn’t matter if you’re trying to build muscle, train your hardest, shed extra weight, improve your nutrition, or if you just want to try working with a personal trainer — if it’s about physical fitness, it’s possible at Jack City. We’ll work with you, at your pace, allowing you to blossom into the best athletic version of yourself.

  • What training philosophy does Jack City Fitness use?

    If you were to take two identical twins and have them both train at Jack City with different coaches, they would be on completely different roads but they’d still end up with the same results. There are some principles of safety and specificity that always apply, but with our veteran coaches, there is no wrong way to train as long there is an openness and commitment to learning.

  • Do you have any referral benefits or package deals for families, etc.?

    Hey, like we said: we think of our clients as partners — and we love helping our people. That extends to our people’s people as well, so bring your friends and family over to see us. You’ll all be rewarded as a thank you for making our Jack City Family bigger and better!

  • Do you have a pool or sauna?

    Not yet — but if you’re looking for a similar workout to swimming laps you can find it with our total body, zero impact, rowers and versa climbers. Based on research, the caloric and metabolic effects from these two machines is greater than that of swimming. So if you’re wondering how to lose fat, increase mobility, and gain muscle, you can jump into our facility and get it all!
