After a full week of narrowing down the men's and women's fields day-by-day in the Olympics-style combined format at Sender One LAX, two more names were added to the ever-growing list of climbers who will take part in this summer's Olympic Games.

Large Number of Gym Owners Face Challenges as the Sport Braces for the Olympics

But by early March, CA was the last start that has not allowed its climbing gyms to reopen. That has caused Kao to launch a colation of gym owners in the state who have been lobbying state officials to exempt gyms and allow people to climb again.

Sender One is amazing! I've been a member here for about 4 years. The staff is amazing and takes effort to get to know members - creating a community rather than just a gym. The climbing is amazing, new routes are up weekly. I've participated in many activities the gym puts on, such as Bouldering League and meetups. They are great, the energy is amazing! I highly recommend a visit 😊

This place was pretty fun for the whole fam. The friendly and helpful staff is expected at a place like this. I liked the variety of walls to climb in the kids' area, and also the openness of the adults climbing area. They are great about safety here, and the cushioning provided is a nice touch to keeping things safe for everyone. I'd definitely consider coming back sometime, maybe just for the fun of it! Our experience was a good one, and I can only review off of that!

They also had some things for purchase at the entrance, like snacks and drinks, climbing accessories, and gear. The place is well air-conditioned and pretty cool inside, just in case you get cold easily bring something to keep yourself warm. Located near Manhattan Beach, this place is in a quiet and sort of secluded area of LA.

Our family really loves (Sender City) at Sender One. The walls are all decorated in a really fun way for the family. They have a good assortment so that everyone will find something they like. The tall tower of foam blocks in super fun to climb up to the top and then just jump off. We all like to climb and come together (2 adults and 2 kids, ages 8 and 10). The employees that work there are great! They are all super patient and helpful and all extremely kind.

We signed up for the intro course, as this is our first-time rock climbing and Steven was a great instructor teaching everything we needed to know to be confident in doing it on our own. We ended up loving it that we actually purchased the 5-day pass. Great customer service, the location in Santa Ana is very clean, and the staff is super friendly. Highly recommend it!

A really nice climbing gym. The facility is clean, top notch and the staff is really helpful. It is an excellent place to learn to climb the classes are well run and there is a separate area for belay lessons.

The kids stuff is really well run. They maintain a high staff to kids ratio. The kids are well watched. Sender City is awesome. It has its own room away from the climbing gym. The kids are harnessed, auto-belayed and get to climb on fun stuff. The after school program is well coached, the kids really have fun and become really good climbers.

Yoga has a separate studio. They have classes throughout the day. Everyone seems to enjoy them. I’m not qualified to say anything about yoga other than to say its fun.

If you already are a climber, you will love climbing here. They have bouldering, top-roping and lead climbing. The routes are changed frequently and the setting is excellent. The gym is first class, and has state of the art cardio equipment, weights, weight machines, TRX, adjustable rings (my favorite), campus board (with half rung spacing), hangboards (including my faves, Moon & Beastmakers), Walltopia Adjustable System Board and a bunch of other to make you stronger. Sender One is an excellent place to train for your climbing adventures.

Talk about the ultimate playground. I’ve been to several indoor climbing gyms before but none like this. Truly a playground for the enthusiast or a beginner who has the slightest idea about climbing. Came here with a friend one evening and let me tell you, a good workout is around the corner. I happen to run into a friend who is an experienced climber. He gave us the run down on top roping and belaying techniques which was cool. This gym is spacious and has plenty of challenges for every level. They also have yoga classes as well as a traditional gym. Not sure if its around the clock but its there. There’s also an area designated for kids… and adults, too. 😛

What is really cool is that everyone is friendly and courteous on the floor. Safety is everyone’s responsibility here. A few strangers offered me chalk before my climb which was pretty awesome. Had it been candy, its a different story. Stranger danger kicks in. As for chalk, meh… should be good. *high five.

Great time at Sender One! We’ll be back
