Being in a powerlifting gym beats a commercial gym all the time and having access to Kilos is a must!

1RM is hands down the best gym of all of SoCal. The vibe, the energy, the quality of the equipment.

I trained with Matt for several years before moving to the East Coast seven years ago. While…read morerecently visiting California, I had the opportunity to participate in the Friday conditioning class, and it did not disappoint. ​Matt is still incredibly engaged with the class, expertly motivating the group while providing the individual attention each participant needs. The best part is that the strong family atmosphere I have always appreciated and enjoyed is still present--a direct result of the positive culture Matt has prioritized building over the years. ​So, if you're looking for a top-notch strength and conditioning program that produces results and fosters a community where members truly encourage and motivate each other, I highly encourage you to check it out!

Cozmosize Fitness has truly flourished since moving to their new location on Railroad Avenue. The…read morespacious facility has transformed into the perfect environment to get stronger, better, and leaner while working toward your fitness goals. I was first introduced to Matthew Cather by my 17-year-old son 11 years ago, and at the time, I thought it was the toughest workout I had ever attempted. I started training with Matthew twice a week, and now I train five times a week--growing not just physically stronger but also mentally resilient. As a 52-year-old, I firmly believe that the key to longevity is a combination of weight training, strength, mobility, and conditioning--all of which are seamlessly incorporated into our program at Cozmosize. The dedication, expertise, and sense of community here make every session both challenging and rewarding. I feel truly blessed to be part of the Cozmo family, and I highly recommend this gym to anyone looking to elevate their fitness journey!

After a couple of heart attacks in 2024, I went through the Cardiac Rehab program at Henry Mayo…read moreNewhall Hospital. Once I completed that, I wanted to maintain my cardio program, and joined the Henry Mayo Fitness and Health Center. I really like this place, for several reasons. I can actually get free memberships at several local gyms through my insurance, but I'd rather pay to go here. It's a more mature crowd, with most people either doing some sort of rehab or physical fitness. It's not a social club or hang out, everyone is serious about what they're doing. I don't have much experience in gyms, but from what I see, they have plenty of cardio machines (treadmills, crossfits, arm ergos, upright and reclining bikes) as well as weight stations with both plate weights and resistance. There are free weights as well and all kinds of support stuff like mats, stretch bands, etc. The place is spotless, with constant cleaning going on, and everyone seems to take the time to wipe their stations down after use. I don't use these areas, but they have beautiful locker rooms, showers, basketball courts and a pool that is half indoor/half outdoor. The staff is friendly and helpful, and available for personal training if you desire. They have tons of classes from spin to balance. Downstairs, there is an advanced weight training room. I go three times a week and always look forward to it. I highly recommend you check them out.

I can't not rave enough about this place!!…read more As a mom of two trying to get back in the gym it feels extremely intimidating, but Henry Mayo does not in the slights make you feel like that at all. I have been coming here for almost a year , 4 days out of the week , every week! I have built strong bonds and a comfort here. I unfortunately left and tried LA Fitness and after 3 days I canceled my membership and went back to Henry Mayo ! It is well worth every penny , especially the kids club! Moms, if you're looking for a SAFE AND CLEAN place to leave your children, so you can take time for you , this is the place !! The absolute best care and kindness they provide is hard to find. I sometimes find them holding my child for the entire hour or falling asleep in their arms !!

This was a great gym, however the owner has let it go over the last year. I wrote a review at the…read morebeginning of the year stating how dirty the gym was., however the owner responded and had it cleaned, so i removed the review. Since then, it has progressively gotten to a point where it is the worst it has ever been. The only cleaning this gym gets is the employees empty the trash. All the other cleaning is left to the members who are good about wiping down the machines. However don't look at the floor, vents, or corners, or the lower parts of any machine, as they have not been cleaned in months. I have pictures I have taken of crumbs by a machine in the open that has been there for months. Its so dirty, i decided it was time to give the new Planet Fitness a try. I know many others are talking about the same issues and hoping it gets fixed, before they decide to leave as well. **Update/ Response**Thank you for your response. You are correct the one picture of the elliptical was from earlier in the year when I left my last review and deleted it after you cleaned the gym and I stated this in my review, however all the other pictures are from last week, including what you call a mat, you said you haven't had in 2 years. It is not a mat, its the base of a podium type stand next to the cubicles by the front entrance. It does look like it hasn't been cleaned in 2 years though . Not sure who the new management is since you have been there for years. You have obviously chosen to ignore the cleanliness of the gym, as I am not talking about it being dirty from overnight, I am talking and showing pictures of things that have not been cleaned in months. I didn't take pictures of the area in front of the treadmills or the speakers by the stretching area or every corner or lower part of each piece of equipment. They are all disgusting.
