    Garbage piece of equipment when it comes to inserting your tennis shoes.

    My review doesn't really apply directly to Planet Fitness but to Matrix Equipment often found within its various locations. Their newest seated aerobic equipment has pedals that do not accommodate my size 12 tennis shoes. Granted, there are much larger tennis shoes worn in a gym. I'm going to 'cut through the mustard'. How can a 'company' such as Matrix apparently not do sufficient quality control? Even when the strap is set to its widest position, I cannot insert my tennis shoes far enough to provide comfort in pedaling so, I can't use this equipment. How could anything this basic sneak pass Matrix? Check out my attached photos. I should add that I really like Planet Fitness and have gone to their locations in Puerto Rico, Kentucky, Louisiana, Minnesota and various locations in California. My complaint with many of the gyms is that overhead music is excessively loud. The facilities are clean and most front desk people except those I encountered in Lafayette, Louisiana are friendly and professional. So, in summary, I've been to around 12 different locations, and 10 were very positive. Positive ones includes the location on Philadelphia in Chino, the Diamond Bar location, the location on Vineyard in Ontario, the one in Corona off of El Cerrito, the one on Foothill near Upland, Baseline in Rancho, the one in Covina, the one off Rancho Rd in Pomona and every other place in California, one in Lexington, KY, one in Lake Charles, Louisiana, etc. The facility in Lafayette, Louisiana (4 years ago) had the worse and most rude front desk idiots. They would not speak and most pretended to be busy all of a sudden when I would walk in. They had a young female manager who was courteous but most of the other front desk people were worthless.

    I'm glad that Planet Fitness has opened up in Diamond Bar, it is in the same plaza as Starbucks, Hmart, and also a few other food restaurants around the area. This place has plenty of parking and also since it is new all the machines are also new. All of the workers here are super friendly and very chill! If you get to know them it makes you also want to come in daily to check up on them as well! It feels like a community here and everyone overall is nice and you also get to stay healthy during the holidays. I've been a member now for 7 months and I honestly love coming here.

    They stay fresh here. Machines are newer and plenty of parking. Individual screens on cardio vs large monitors. I like the design and use of space here better than most of the other locations I've frequented. I don't normally have to wait to use any of the machines in my rotation and if I do it's very minimal. Thanks for the upkeep!

    Felt the need to leave a review because I've had nothing but a great experience here…read more My little brother and I were looking for a gym after moving back home, so we tried several in the area before checking out Curl. We met with the general manager Gustavo, who was very friendly and accommodating in helping us find the membership that made the most sense. I didn't end up getting my own membership since I'll be moving out again in a few months and Curl doesn't have many locations, but I've been able to come as my brother's guest. We even got my mom to sign up which says a lot given she's pretty high maintenance about cleanliness and wasn't going to the gym at all before this. Now she goes almost every day and loves the zumba classes. In my opinion, this is the best all-around gym for the price. It's cleaner than 24 hour and LA fitness, it's never so crowded that I'm waiting forever for equipment, and unlike planet fitness, it has a great selection of free weights. They also have newer equipment including a hip thrust machine and pendulum squat. I used to go to 24 hour whenever I came home on school breaks, and I've never been able to grab a spot at the squat racks with bumper plates. At Curl, I've never had that problem, even though I come almost every day. On top of that, Gustavo and the rest of the staff have always been welcoming and helpful. Overall, it's been a really positive experience and I'd definitely recommend Curl to anyone looking for a solid gym!

    CRITICAL UPDATE (Sept 8): FORGERY & UNAUTHORIZED BILLING FOUND…read moreI am updating my previous review because this situation has escalated from deceptive sales tactics to outright fraud and forgery. The Forged Termination Form: Instead of replying to my September 7 email, the General Manager, Gustavo Guzman, deliberately started a brand-new email chain to send me a Membership Termination Form. This document features a forged signature submitted completely without my consent, stating that I am liable for all outstanding fees and charges. Hidden Fees: Shockingly, the form he forged contains absolutely no financial fields, dollar amounts, or fee disclosures. Mr. Guzman entirely hid the financial implications of this cancellation from me and never declared any charges. The $130.99 Unauthorized Math: I immediately called ABC Fitness Solutions (the third-party billing company that collects fees for Curl Fitness) directly. They confirmed that this forged cancellation request has officially scheduled an unauthorized $130.99 charge on my account for September 25 ($99 termination fee + an additional $31.99 monthly fee). Mr. Guzman cannot legally forge my signature to dictate my payments, nor can he use a medical code to cancel my contract while simultaneously charging me a waived termination fee and double-billing my prepaid dues. Current Actions Taken: Corporate Escalation: I reached out to the Curl Fitness Corporate Office at 949-673-7777 and have been directed to escalate this to Mr. Bill for an immediate corporate fraud investigation. Federal Reporting: I have officially filed a fraud and forgery report with the Federal Trade Commission at reportfraud.ftc.gov. BBB Dispute: A formal complaint detailing these fraudulent practices has been updated with the Better Business Bureau (BBB). Do not trust Curl Fitness Diamond Bar. They will sign your name to legal financial documents without your permission. Check your bank statements and fight back!

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 don't have to worry about whether the squat rack is open or if the machine i want is taken. I don't have to think about what body parts to target.

I knew I wanted to workout, but didn't have the time nor energy to build out a workout routine, meal plan, and even keep myself accountable to just go...until I met coach daniel. After days of research and personal consultations with multiple trainers, I chose Daniel. His energy is infectious and most importantly, he is understanding of what goals you are trying to achieve. At first I wanted to to build strength, but later on I switched to running. His knowledge and versatility of how to pivot programs is mind blowing. One thing worth noting, he is very precise and he will teach you the science behind the movements. A teacher + coach = win! I know the biggest hesitation with training is cost, however, your health bill will be 10x if you don't do anything about it. Im glad I picked coach daniel because I have been able to achieve a healthier lifestyle, crush personal records, lose 30 pounds, and be more disciplined. Thank you coach daniel for what you've done for me and I look forward for whats to come!
