    Love my system and can't wait to learn everything. I would have rated it 5 stars but not enough pins for the attachments!

    Love the K1S

    I purchased the TC K1S all in one bundle. This machine comes very well packaged to eliminate shipping damage. The assembly instruction were thorough but if the pieces would have a sticker attached to corresponds with the part description pictures it would be very helpful. Landmark's Customer Service response time to our email question's was outstanding, we had our answers by the next business day at the latest. Sometimes within minutes of emailing. The machine itself is an outstanding workout machine with everything needed for a quality workout, this machine is clearly designed to provide years of rugged use, and it comes at a great price.

    best deal out there

    The unpacking process took a bit of time because of how well packed everything is. Finally found the instructions in box 3. Seems a little counter intuitive to place them in box 3. ?. We are up and running now! - assembly went well, though the instructions aren’t as good as they can be. but other than that, thank you for the quality product at an attractive price. My wife and I absolutely love the K1S

    The K1S is working out really well for us. My teenage sons love it and are using it daily. Would definitely purchase again.

    It was exactly as advertised. The customer service was top notch, i would certainly buy from landmark again. Equipment is great qaulity for home gym, Smith machine is par, nothing special but functions for what I need. Wish it had more depth, also my biggest gripe would be better instructions. There's things that need to be done in order and there's minimal written instructions. Other than that, it has been a blessing of an addition to my home gym. Cables are buttery smooth on the aluminum pulleys and for more weight you can had a weight peg. I use it almost every workout, if not all. For what you get compared to almost every competitor it's easily the best bang for your buck, Quality and functionality.

    I ordered the TC EXT-3 All-In-One Gym BUNDLE. I love this equipment, my neighbors even come over to workout. High quality and easy to use. I put it all together myself in 2 days. Daniel answered all of my questions and gave me his professional opinion when needed. I feel indifferent about the pull-up bar on this particular model, they seem like they were an afterthought based on the quality of everything else. But I haven’t used them much since it’s so many alternative workouts I can do to hit those same muscles.

    I was looking into a small gym for myself and my employees, I didn't have a ton of space but wanted some equipment and flooring. Daniel took my call and we discussed some things over the phone, he emailed me some options and quotes, we added and removed some things and a couple days later I had finalized what I wanted and what would work for me and we pulled the trigger. He was prompt to reply and awesome to work with. Thanks Daniel! Edit 2-9-25: I finally got the new gym room setup and have learned the ways of the Q10 all in one machine. I definitely like it, the 2:1 and 1:1 cable ratios are great for lat pulldowns when you would normally max out the weight stack on a 2:1 ratio. The rubber flooring doesn't have a smell like some rubbers do. I had a couple small issues and Daniel took care of them. Word of caution regarding the Semtex bench... It's a tank, I have no doubt it will outlive me, however.... If you have a wife who's 4'11" and not the incredible hulkess then they will have a workout moving it around. The bench must weigh 100#. It's solid though!! Just heavy towards the end of a workout. 😆 I also 3D printed brackets to hold the jammer arms, dip arms and other things to my wall. The only thing that I did upgrade was the weight stack pins, the blue ones came with the machine and they have weak magnets, I bought some from Amazon with a full circle magnet and the done come loose. The pup also approves.

    I have been searching for a high quality treadmill for several months after numerous issues with our current Nordictrack, and their abysmal service. I started looking more locally and found landmark athletics. Daniel promptly returned my call and answered all of my questions, even making additional calls to quell some of my concerns regarding warranty and service. He walked me through the entire process and helped to coordinate delivery on my schedule. Overall Daniel made me feel extremely confident and reassured about my purchase of 3G cardio Elite Runner treadmill. I look forward to working with Landmark Athletics in the future, and highly them for anyone’s fitness needs!

    Worked with Daniel through the process of upgrading my home gym. Friendly, personable, relatable, and full of knowledge. Took the time to address all of my questions and more. Was engaged throughout the process and really helped me pick what was best for myself, not just trying to make a sale. Will update my review on the TC EXT-3 when it arrives with the leg extension attachment and lat pulldown attachment. Still considering adding the upgraded bench. From a customer service standpoint, Daniel was great, quick responses and reliable.

    I bought TCK1S for my home gym - I’m very happy with all the different exercises I am able to do - should have upgraded to the leg extension bench so now have to get one. Downsides would be instructions for assembly are very vague so you have to look at the assembled pictures a lot and after purchase I realized there wasn’t a weight stated for the smith bar machine so sent a message but haven’t received an answer

    After too much research I landed on purchasing a functional trainer from Landmark Athletics today. I went with the Q10 machine and worked with Daniel who was great to work with. He was very patient and thorough in helping guide me along the best path for what fit my needs. I’m looking forward to receiving and installing the equipment and will be sure to follow up with additional review detail once done and I’m able to use the equipment.

    We purchased the TC K1S smith machine about a year ago and it has been an amazing addition to our small home gym. It gets used almost everyday. We had one issue where one of the cables broke but in reaching out to Landmark their customer service was exceptional. Jeff responded almost immediately and within a day a replacement cable was shippped out. We couldn’t be happier with our purchase. Our only issue now is our son has gained so much strength using the gym we may need to upgrade to the heavier duty rack soon!

    I have been comparatively shopping an "all-in-one" home gym machine for the last 3 month and I found exactly what I wanted with the EXT-3 by Landmark Athletics. I am very particular about the product, the price, and customer service when I look to make an investment. I called 4 major manufactures in the "all-in-one" home gym arena and only one company answered the phone. Daniel at Landmark Athletics not only answered the phone but he spent quality time with me getting to know my fitness needs, my family needs, the space I was looking to make into a home gym and all the benefits to becoming a Landmark Athletics customer. You don't get service like this anymore and Daniel made my decision to invest in the EXT-3 simple. Here is my advice; stop shopping, call Landmark Athletics, ask for Daniel and get your home gym built so you can start working out. Thank you Daniel and Landmark Athletics, you earned a customer for life - Mike

I would recommend to anyone looking for a real partner in decision making. ABSOLUTELY FANTASTIC!!

    Customer service is absolutely amazing!! Product bundle is pretty good. Reason the 4 stars: I have never had so many homicidal fantasies as when I was trying to follow the assembly instructions on the TC Q10 unit I bought. Had to keep taking it back apart because the instructions have the order of assembly incorrect or poorly shown. Added ballpark 2hrs to the assembly. The video they just made helps a little but also does not accurately portray the assembly (namely, installation of the smith machine poles and correct orientation of many components,).

    Jeff has been great to work with for the last several months. He listened to our wants and needs and worked with our budget. Our gym has been open for 2 months now and members comment about how nice the layout is and the equipment. He has communicated well throughout the process even after back ordered items arrived. Our custom turf looks awesome! Jeff still checks in to make sure everything is going well and equipment is running smoothly as well. 10/10 recommend.

    I have ordered fitness equipment from Landmark Athletics on three separate occasions. Each of the occasions were exceptionally smooth experiences and I couldn’t be happier! The equipment arrived promptly and well packaged with decent instructions. I tend to shop around a lot and found the prices they offer have always been the most reasonable. I called in to speak to a rep to make sure all my questions were answered such as shipping information and to confirm that there were no hidden costs for shipping to my delivery address. The information I was given was clear and easy to understand. Jeff is amazing to deal with and very knowledgeable. He took the time to genuinely help and guide me to purchase the right equipment for me to achieve my fitness goals, not just recommending the most expensive equipment. I appreciate his honesty and not rushing me to make a quick decision. Landmark Athletics is my go to fitness equipment supplier as I continue to expand and invest in my home gym. I highly recommend these guys if you want a solid home gym set up. Absolutely 5 star experience!!

    From start to finish everything went smooth and service was top notch. I ordered directly through Brett on a Friday morning and I received delivery on the following Wednesday. Instructions were a bit fuzzy at times but assembly was smooth and all parts lined up perfectly. I ran into an issue with the cable routing and a quick to Jeff and he not only provided pictures but also a short video on how to properly run them. Would definitely recommend this company and buy from them again.
