    Be at 29.7 percent body fat before training
    Steven L.

    I grew up in Diamond Bar and I've tried all the big and small bouquet gyms around Diamond Bar and Walnut (I don't want to name names but if you are from here, you would know which ones I'm talking about). Then I found fitness 100. Fitness 100 is a gym that has a nice environment and nice people inside. If you're just getting started to fitness and worries about ego at the gym, Fitness 100 will make you feel right at home and non of that ego and face things exist here. I started at 29.7 percent body fat and obese to now. Feels very comfortable here focusing on my own training with my trainer. There's about 7 regular trainers that trains clients here. EVERYONE of them and I mean EVERYONE is really nice and friendly. There's also a Zumba and yoga room in the back of the gym that can let clients stretch, and do other activity a besides weight lifting. And last things, the owner Steve. He's the icing on top man! He's so sarcastically funny it's unbelievable ;) Give fitness 100 a try guys!

    Ask the Community - Fitness 100

    Confused with the pricing, how come it's only 15 dollars a month with trainer and 40 without trainer? Is this correct?

    Thanks for the question! The original price is $40/month if you want to use the gym without purchasing personal training sessions. We offer an ongoing discount if you do purchase sessions.

I lost a ton of weight as well as put on a lot of strength, and also learned a lot as the trainers are super friendly, informative and educated. You can pretty much ask any trainer for advice and none will hold back from helping you. My main goal was to improve my overall health but my confidence is probably what got boosted the most. If you're looking for a private space with premium equipment and want to improve your health, without the premium price tag. This gym is for you.

There are a variety of trainers and they're all great, Though each has their own style, it's evident that they all genuinely care and want you to get stronger and reach your specific goals. I really like that they give you a proper warmup before each session to ensure we've prepped the appropriate muscles to be worked that day. They also have us gradually step up to our working weight on heavy lifting days. All to protect us from injury and ensure we're primed before the heaviest lifts. No two classes are the same even if the same muscles are being trained each particular day. There are days to work on power and days to work on strength. Each strength day starts with a heavy lift (barbell back squats, deadlifts, chest press) followed by accessory exercises using dumbbells, kettlebells, curling bars, barbells, etc. It's a well rounded program. Equally challenging for men and women. I've been attending for about 4 1/2 months. I like it so much I signed a 6 month contract after attending for a few months using ClassPass.

I liked the exercises she does, it's different than the other places I've been to.

    This review is way way waaaaaayyyy past due!! Where should I start?…read more My Story: So, a little over a year ago, I had miscarried what would have been our 4th baby. I was going through such a tough tough time both mentally because of the loss and physically from being pregnant. I had done everything from boot camp, yoga, and cycling. You name it, I've done it. While checkin out my friends posts and stories on Instagram, I kept seeing posts for a facility that opened up in Chino Hills, Self Made Training Facility with Pablo from Ambitious Fitness. I contacted him and the rest is pretty much history. Myself, my husband, niece, nephew and son all train with Ambitious Fitness. Best things about Ambitious Fitness: 1) Pablo and his team (and I mean every single one of them) are incredibly passionate and love what they do, and it totally shows in their energy and the way they carry themselves. 2) They have this amazing ability to push you beyond what you think you can do. You would have never thought that this Asian girl who only played badminton and piano as a sport could deadlift 275lbs. 3) They make sure you will achieve your goals and get results. My results: Being only 125 lbs in college, it was hard to believe I would get to as much as 168lbs and 36% body fat, but I did. After a year with Pablo I got down to 148lbs and 19.1% body fat at my lowest. I am more physically fit than I ever was and mentally stronger. Hit Ambitious Fitness up!! If it's for your health and for your future, it's definitely worth a try.

I would have never considered myself "overweight" but knew I needed to lose a few pounds. I've tried the traditional membership gyms but always found that I would lose interest or motivation. When I started inquiring about personal trainers, Mia was very prompt at answering. During our consultation I did a body fat scan and was shocked to find out that I was nearly 25%. We talked and I learned that it was less about the weight and more about body composition and fat/muscle percentages. Due to my work schedule we were able to meet twice a week for an hour a session. Mia adds good variety to our workouts and I definitively know that I push myself more during our sessions that I normally would have if I were doing the workouts by myself. She also places an emphasis on nutrition and offers advice on what to eat and what to stay away from. The last couple of years my diet has gotten progressively worse, and she's been a great help in getting me back on track. I've noticed that I've started making much healthier choices in the foods I eat. still have a ways to go but would highly recommend Mia for helping you get you to your goals!
