Great, laid-back local gym. Prime Fitness has everything you need for a good workout. The equipment is clean and well kept, and members get a key fob for 24-hour access even on holidays. I've been working out with Keith for a few years now. He's the only person who can take me through a good leg workout without aggravating my back issues. He's put so much thought into the equipment and layout of the gym so that anyone can get what they need from it. I highly recommend both Prime Fitness as a gym and Keith as a trainer if you're looking for an awesome, unintimidating place to work out, and/or inspiration for improving your fitness level.

The location is great -- on Washington across the street from Bronx Pizza. The free parking is a huge plus; no two-hour limit so you can take your time in the gym. Great equipment in a nice space; gym is always very clean and people are friendly. The training is what makes this gym stand out from the crowd. Keith uses a variety of techniques to challenge you and gets results. I went from 22% body fat to 10% in 12 weeks this past year. I didn't think that was possible at my age (46).

I love this gym in Hillcrest. It's a brand new facility with up to date equipment and a personal feel unlike the mega-gyms. It has 24 hour access for all members which is super convenient. I also highly recommend training with Keith. He is incredibly knowledgeable about fitness and diet, and extremely effective in evaluating a client's abilities and getting great results. I can't recommend Prime Fitness and Keith highly enough.

I have been working out with Keith Diedrich, owner of Prime Fitness Training, for 18 months now, and I have made impressive gains in my strength, fitness and stamina. Opening his own gym with personally selected equipment has made my workouts even more rewarding. All of the equipment is easy to access and designed to give a full body workout. I love the 24-hour access. It's not a big box gym but it is spacious enough to be comfortable. I've never had a problem with parking. Anyone looking for a gym should check out Prime Fitness. Talk with Keith about your fitness goals. He is very knowledgeable about fitness and he practices what he teaches. I know because I'm an example, an almost 68 year old example.

Great place to work out! Keith is a great trainer. I have lost about 35lbs and can finally wear a bikini again.The gym itself is a nice space. The colors seem to give me energy. The bathroom is spacious and there are lockers. There is a filtered water dispenser, and 7-11 next to the gym if you forget anything. The gym has a high ceiling and padded flooring with a mix of sealed concrete. Very cool.Keith will let you play any music you'd like during your work out. The gym has numerous new machines and weights. There are also lockers available. The gym is never crowded and has all new equipment, is clean and orderly.Keith and I (as well as my husband) have been working out together for about 2 years. During that time he has taught he discipline, as well as given me nutritional advice and work out tips. Thanks to Keith I now know how to use various gym equipment, and I understand pulse and blood pressure.Keith is a patient person and will not complain, nor will he ever raise his voice or criticize you. He is a great person with seemingly endless bits of fitness and nutrition information. He will gladly help with a meal plan.I highly recommend Prime Fitness and Keith as a trainer if you're looking to lose weight, get in shape, and learn self discipline.

Great gym, awesome features including 24hr access and super clean equipment. Keith is a total pro and really cares about delivering functional, truly strength building instruction. Camaraderie saturated and motivational during the whole workout. Fresh to the area, don't hold back from coming to check it out for yourself.

Love this place. Great selection of weights - both machines and free weights. There is zero intimidation and you can go at any time of the day. I've also been using Keith for training and he is by far the best trainer I have used. He mixes things up and constantly keeps the muscles confused. Highly recommend Prime.

1. The gym is very clean. 2. The equipment are always in top shape. 3. Keith is very knowledgeable when it comes not only to exercise science, but the human body. 4. The environment is very professional, yet friendly. The other patrons encourage one another. We are also never competing for the same equipment.

Finally a nice clean not crowded 24 hour access gym. Quality equipment, Kind of pricey but worth it.

Where to begin, I have been with Prime Fitness Training for 4yrs now & haven't looked back since. Keith's first observation of me was that I was, "skinny fat!" Lol Although I was put off at first by this, I didn't realize that this was the type of forward treatment that was needed for me to begin my type of self improvement. For my reluctant self, it took a few attempts to begin & with continuous reminders from Keith encouraging me to push myself, I powered over those hurdles & began this marathon of an adventure. Results were showing reminding me everyday why I was doing this for myself. Now, not only have I reached my goals, I have created new ones.. Overcoming new challenges & only thankful to have this amazing Trainer & friend in my life. If you're reading this review & looking for a change. I 100% recommend consulting with Keith to have him take you to those next steps in improving ones self. He will motivate, drive & push you to be a better you :)
