Flex Gym has truly impressed me with its combination of affordability and quality. Jared is friendly, helpful, and always quick to answer questions.

The equipment selection is fantastic—clean, well-maintained, and there’s a wide variety for every type of workout. One of the best parts is that I never have to wait around or fight over machines; there’s always something available, even during busier times.

Overall, Flex Gym delivers great value, great service, and a great workout environment. Highly recommend!

Passing by sioux falls for the day and I was looking to get a quick pump . The owner set me up with a day pass fast. The gym was not staffed. But no worries at all the owner buzzed me in remotely after the payment. This is the exact atmosphere I want in a gym. No fluff straight to the point. Come here and pump some iron.

This place hits home. Its my favorite gym of my adult life. Old school machines that are tried and true, with everything you need to achieve your goals. The place is spotless, because the members help clean! That's right, the community is amazing. The owner is very intelligent and helpful.
Even though the fans in this place work great, it just doesn't replace AC.
If the AC was set to 72-74 Memorial Day-Labor Day it would be 5 stars 😉.
UPDATE: even though my extra layers of fat want a colder environment, you just can't beat the value this gym and community has to offer. 5/5.

Great gym. Simple. What you need.

Owner was a excellent communicator. I needed a place to lift on Easter, he texted me and got me in and situated easily.

If I lived in Sioux Falls this is where I’d go.

I spent 9 weeks in sioux falls for my physical therapy clinical at a hospital. I enjoyed being at flex gym it is a quiet gym which is perfect for me, you can easily get on equipment, and they got plenty of barbells to lift some heavy weight. I had a great time here, and the rates are quite reasonable and the owner is great! Highly recommend.

Excellent gym expiernce. I’m from out of town and the gym I usually go to was closed for Easter and I needed to go. The owner had a fast and easy daily/weekly pass that that I used for a great price. The equipment pretty much covered all workouts. The gym also has a pr board (something all gyms should have in my opinion).Needless to say, if you’re in this area, this should be your first option.

Stopped by while visiting Sioux Falls for a work trip. I was greeted via text by Jared in regards to my inquiry for a day pass. The day pass cost was fair, and was promptly let in the building within 1 min of my arrival to the gym, all via remote.
The gym itself is old school vibe. Definitely more suitable for powerlifters, body builders or lifters who just generally are serious in regards to there training and performance. I was able to connect my iphone to bluetooth and use calibrated competition equipment (Kilo plates, Rogue ohio power bar and combo rack). As a USAPL member and competitor, finding the right gym while traveling is key in my training and performance. Thank you Flex Gym for providing a home to your local community and travelers such as myself. I will be back each and every occurrence that I visit Sioux Falls for work.

I got a week pass to lift here while I was in town for work. Jared was quick to respond and made it easy to get signed up. Flex had everything that I needed and more, the environment is perfect for anyone who is serious about lifting. There is a bar for everything, all the types of plates, platforms. I got to use an Ohio Power Bar, same as I have back home. My favorite was the bench set up and there were Ivanko Dumbbells.

Worth getting a membership if you are in the area! Will be returning to Flex the next time my job brings me to Sioux Falls.

DO NOT get a membership at Flex Gym in Sioux Falls, SD especially if you’re a woman. The owner cares only about how much money he’s bringing in and won’t put that money back into the gym. If you want something in the gym you have to buy it yourself or he won’t get it even if many members ask. There has been multiple instances where a woman was touch by someone without consent or anything and only one person that was kicked out after months of harassment. Also the owner lets members that have been there longer than you say whatever they want to you but if you retaliate in the slightest expect a cancellation of membership with a text without even getting the other side of the story. Apparently swearing in the gym is a bigger offense than someone trying to fight you over a bench. This isn’t the only instance someone was kicked out for no reason or because of someone else’s actions. Clearly the owner does not care about the people in the gym and only listen to the people who complain about every little thing. I will say it again DO NOT GET A MEMBERSHIP AT FLEX GYM.

Wouldn't recommend going to this gym. The gym owner says it's ok to listen to music and have the doors open cause there's no air in there but once you do the neighbors behind the fence want to start screaming at the neighbors and jumping the fence trying to fight them. There is another incident with another gym member was benching and the guy behind the fence shined a mag light right into his eyes. Luckily the other members ran over and grabbed the weights before he dropped them crushing his chest. The owner will not do anything but cancel your membership and call you the aggressor. I feel sorry for those gym members paying for a membership and have to deal with neighbors drama. I personally will not be getting a membership there. I know everyone has their own opinions and each to their own. Just if you do get a membership there and the neighbors start their drama then prepare for your membership to be canceled due to you being the aggressor.

Great gym! I was only in town for a day and so I messaged the gym on Facebook the night before coming to town (assuming I’d get a response in the morning) and they responded that night! Great equipment and clean facility. You can even sync your device to the speaker system which was super neat. The owner was also extremely nice. I would definitely return if I’m ever back in the area!

Was passing through Sioux Falls twice this last week and was wanting to stop somewhere to train. Communication with Jared through Facebook messenger was super fast, easy, and clear and getting a week pass was no problem at all. The gym had everything I needed and the facilities were terrific. It's members were respectful of each other and the gym too, evidence of a strong gym culture. Support local gyms!

Great gym. Old school. 24/7 365. Great owner. Just moved into a new space and added new equipment. You'll rarely ever have to wait to get in a rack or on a bench. Go to any other local gym and look at the rules signs. Basically none of those rules apply to Flex. Use chalk, blast music, lift without shoes, make some noise... nobody cares. Small, friendly community always willing to give help/pointers/spots if you ask.

The Best Around!

Every year or 2, I visit family in Sioux Falls. I called Flex Gym, got a week pass and a key fob, and lifted every morning I was there. Let me tell you… it was AWESOME.

Flex has some great equipment that most gyms don’t carry. They have quality Rogue Ohio Power Bars, Texas Power Bars, and elite TFS equipment that’s well-maintained. Additionally, they have plenty of steel and bumper plates for powerlifting, strongman, and olympic lifting needs.

The owner personally met me and gave me a great deal for the week and has ensured that my lifts didn’t suffer while on vacation.

I highly recommend Flex gym to anyone who is serious about strength training or wants awesome customer service.

This is my favorite gym of all-time. Jared, the owner, is super nice and personable. The members are friendly, and it feels like a real community. Love the classic weight machines, dumbbells, platforms, chalk. Can hook up your Bluetooth to the speakers and rock out. The big dual garage doors bring in natural light and fresh air. I feel so fortunate I found this place.

What a great gym!! I was in Aberdeen for the day and needed a place to train. I was 2 weeks out from a show and couldn't miss. I called around and and Jared, the owner, got back with me. He went out of his way to accommodate me to be able to come in. The gym was perfect. It had everything I needed and nothing I didn't. This is the gym I would train at if I lived in Sioux Falls. I would give 10 stars I could. Go in and see for yourself. Thanks again, Jared!
