Back Stretch Twist Machine

The knee pads are cushioned and sit on a track that slides back and forth as the body moves forward and into a crawl position. The hand grips extend upward and can be adjusted for height.I set it up in my living room and use it most mornings. The crawling motion is kind of awkward at first and takes a few sessions to feel natural but the lower back gets a real stretch out of it. The twist in the movement is subtle rather than dramatic and I think that is a good thing for my . There is no resistance adjustment so the challenge comes from bodyweight and controlling the pace of the movement. The padding on the knee rest is adequate but a little thin for longer sessions and the arm rest padding started separating from the surface after a few uses. A bolt on the cable assembly came loose early on and needed retightening. It is not foldable so it takes up a permanent footprint in my spare room.

I’m really impressed with this trainer. It feels sturdy, smooth, and well designed, and I love that it gives such a great low-impact workout while still engaging the whole body. The twisting motion adds something different from a typical cardio machine, and it really does make the movement feel more effective and challenging. The padding is comfortable, the adjustable features are helpful, and the overall build feels solid and secure. It’s also a huge plus that it doesn’t take up much space and runs quietly. Great machine for anyone looking for an effective, joint-friendly workout at home.

This only required a little aassembly and was easy to put together. It is made well and has no problem supporting my husband who weighs 175lbs. It really does work your core and I also noticed improvement in my back from tensing while going thru the motions. Its a good choice for low impact toning. I've also found it good for stretching. It has good soft padding on the knee.

Works great, fantastic workout, great build, easy to assemble, stable but lightweight, smooth movement, great flexibility and motion workout.The movement feels smooth and controlled, especially with the knee support and adjustable hand grips helping maintain good form. It’s easy to switch between different motions, so you can target core, glutes, and overall mobility in one session without needing multiple machines. What I like most is how approachable it is for everyday use. It doesn’t feel intimidating or overly intense, but still gives a solid workout when used consistently. The steel frame feels stable during use, and the compact design makes it practical for smaller spaces.Great workout machine!

Ordered this for working out.The ab core machine is definitely low impact. I would not use it alone expecting to lose weight but in addition to a cardio program. I don’t work up a sweat with this machine but I don’t necessarily need to since I usually walk for 30 minutes before using it.The machine is easy to assemble and easy to use, the movement is basic core strength moves. Overall I like it . And the movement is great.

The C. 4/5 Verified August 16, 2026

I'm still not sure I'm sold on this thing being a good use of my workout time. It's definitely non-impact, but it's also pretty easy. I don't feel like I'm doing much. Also, the pads for the knees are thin and you attach them with a couple pieces of double-sided tape. They won't last.With all that being said, the device is sturdy and everything moves smoothly and quietly. It feels like it'll last forever (aside from the aforementioned knee pads, which are cheap and attached in the jankiest way possible)

This does EXACTLY what it says it does - it helps to stretch the in a low impact way. When I wake up in the morning I often start off with a stiff lower back. This pain is not due to my bed, it's due to stress and tension. I hop onto this twister and spend about 5 minutes using it slowly to get the pain out of my lower back. After that, I can go about my day.It took about 30 minutes to assemble and prep it for use. The cushioning is comfortable enough for me - it is not plush but it also has plenty to make it comfortable to use. Both knee sections glide easily. The handle bar arm rest also twists without any hang ups.I love that you can adjust the amount of incline and you can adjust the height of the handrail because if my husband ever decides to use it I can make it fit his frame. It does have a screen to keep track of time and calories and a count.Easy to use and a great stretcher for the back!

The E. 5/5 August 5, 2026

This machine is fun and it feels really good to use. The padding where you put your knees is thick and really cushy. I wouldn't have thought exercising in a crawling kind of motion would feel good, but this machine is surprisingly comfortable.The stretch you get is amazing. My lower back and hips feel so much better after using this. As for the workout, it's really pretty good. I feel like it's engaging a lot of my body. I can feel it in my thighs, glutes, abs, and arms.It doesn't offer a lot of resistance. I really wish there was a way to turn that up, but I think your body weight and having to balance yourself makes it at least a little more challenging. I don't mean that I am falling off or anything. I feel secure and stable on the machine, but it's more like you kind of have to balance the movement of your legs back and forth.It also has a place for you to put your phone while you work out, so you can watch things while you work out. Because of that, I actually really enjoy using this machine. It's really helpful for my hips and sacrum, and I feel like I'm building up a little bit of muscle.

Jj 5/5 Verified August 4, 2026

I was immediately hooked when I first saw the advertisement. I did some extensive research....and when I tell you it is SO WORTH IT!Putting it together was a breeze. It's a (little) heavy. It glides unbelievablely smooth. Its not loud. And its ergonomic friendly.With consistency, I do not doubt at all that results will be seen and felt!!!

Just M. 5/5 Verified August 1, 2026

This machine is comfortable to use. The mechanisms glide nicely. There are pads for arms and legs with sufficient padding. It’s not foldable, but I have stored it in a closet just to see if I could. It takes up a lot of floor space.

Lalalinda 4/5 Verified July 28, 2026

It’s made out of plastic light plastic it does the work but your knees hurt a lot I think the knee part should be bigger . It’s easy to put together no instruction need it . I think it’s to expensive for what it is . Not sure if is going to be durable .

Amarilis R. 3/5 Verified July 20, 2026

Very interesting ab machine. Very easy set up and very difficult to use based off your level of fitness needed in order to use it appropriately. Very challenging and hard. I really have to work my way up to using it. So far it’s been a good workout. Very stabile and doesn’t take up much room.

Friendly R. 4/5 July 16, 2026

Pretty good product

Angel B. 4/5 Verified July 11, 2026

Angelica S. 5/5 Verified July 9, 2026

It works.Easy to assemble. Starting breaking up in less than two months.Grinding noises began after four weeks and residue all over the floor.After two months, it’s garbage as the right side only slides about halfway with force

James S. 4/5 Verified July 1, 2026

This is a great item. It arrived fast and with no damage to the box. The Twist Stretcher came with great directions and was very easy to assemble. It provides a great workout and was easy to use. I definitely recommend this item, it was an awesome buy.

Skyler 5/5 Verified June 28, 2026

I am very glad the majority of this is mainly built shipped due to the frame and you just need to install the handle and pads area. Initially I was a bit scared as well for the build. In the main body of unit, was wrapped in a big bag with 2 bolts loose inside. Then as I laid things out I thought, "oh no" I was missing 2 bolts. Nope, the knee pad area had 2 bolts attached, and somehow the other 2 bolts were from this area. Everything went simply and quickly. The pads are nice and thick. The movement for the arm rests and knee pads glide and swivel smoothly, very nice. Props up against the wall to be unobtrusive as well.

Atomic T. 5/5 Verified June 17, 2026

Fast delivery and easy assembly

Ken V. 5/5 Verified May 28, 2026

The stretch and twist motion is different from typical home gym gear, and it takes a minute to find the rhythm without feeling ridiculous. Once you get it, it does work the core and shoulders without the same pounding you get from higher-impact cardio. The padding helps, especially around the knees, but this is still exercise, not magic furniture.

Tibby 4/5 Verified May 22, 2026

I like this one but it don't have resistance bands to go with it but it's overall ok

Monica J. 3/5 Verified May 11, 2026

I really appreciate this fine twist.Stretcher, you do have to assemble it and it can be a little tricky when it comes to assembly, but if you take your time, you'll be able to get it together.And it will work great.This has been quite the beneficial for me, and it's allowed me to help to stretch my backrease, my mobility.

T. W. 5/5 Verified May 10, 2026

This machine is surprisingly sturdy and smooth once it’s set up. The steel frame feels solid, the knee pads are cushioned, and the hand grips adjust easily so you can find a comfortable position. The crawling motion is low‑impact but still gets your heart rate up — basically a workout that looks easy until you’re 30 seconds in and questioning your life choices.It stays stable on the floor, doesn’t wobble, and the movement tracks straight without drifting. It’s a good option for full‑body cardio that doesn’t involve jumping, running, or anything that makes your joints file a complaint.Pros:Sturdy steel frameSmooth crawling motionAdjustable hand gripsLow‑impact full‑body workoutCons:Takes up more floor space than expected

Kookie 5/5 Verified May 5, 2026

Extremely simple to use and the movements are nice and smooth throughout. To my surprise, it works better than I expected as a low/no impact option. I can feel it through my forearms, shoulders, hips, thighs and core. It's easy enough to add to my exercise routine and makes for a good cardio workout. When done, it stores away against the wall taking up minimal room until it's needed next time.

Lee 5/5 Verified May 4, 2026

I purchased this for myself so I can get some more movement in during the day, but I shouldve just purchased it for my kids! They have so much fun on this thing when im not using it, and I love that because it keeps their little bodies moving! I love how easy it was to assemble, the padding is just right, and the tracker is a very nice touch. It is also Lightweight and easy to move around to store.

Rebecca 5/5 Verified May 2, 2026

As someone who loves working out at home, it is a fun and challenging addition to my setup. The crawling motion really fires up your shoulders, core, legs, and cardio all at once. It’s low-impact but still a tough workout. The adjustable hand grips help you find a comfortable position, and the knee supports are nicely padded. The steel frame feels robust and stable too. If you like functional fitness and want something different from a treadmill or bike, this is a great full-body workout machine

Jltrendtrack 5/5 April 25, 2026

This trainer provides a unique full-body workout while remaining gentle on the joints. Assembly is straightforward, and the motion feels smooth during use. It’s a great option for adding variety to a home fitness routine and staying active regardless of experience level.

Crystal 5/5 Verified April 24, 2026

I received what was described and on time. This is well built and a great exercise you can prop the front part up on a chair if you like a more vigorous exercise and it will definitely work your abs and easy to put together.

J. D. 5/5 Verified March 30, 2026

I ordered the twist stretcher as a way to get a workout in when I don’t have time to go to the gym. Set up was super easy and self-explanatory. It does not take up a lot of space which I love. It is very easy to use and has nice padding. I use this almost every day just to get my day going and it has been the perfect machine. It’s a great price and works great. I would definitely recommend.

Customer R. 5/5 Verified March 28, 2026

It’s easy to put together, simple to use, I think it’s works well toning my back and belly, when I am constantly using it.

this machine is easy to set up and easy to use. You get a full body workout without too much stress or hassle. it's the perfect workout without spending lots of money at the gym. it helps to stretch the muscles and relieves tightness in the hard-to-reach places. the machine is a great price and an economical purchase. I recommend this machine.

Edie B. 5/5 March 26, 2026

This is so much better than an a roller! I’ve used many a machines and this is the only one I can say works better than the ab roller. From crunches to oblique twists to leg raises I’ve tried most core exercises and machines and by far this is in the top 5 machines that I love for abs. The twisting motion and sliding feel organic unlike ab machines that can feel painful or forced and even sometimes cause injury. Using this machine will help me carve out my core and strengthen the abdominal wall that I’ve damaged over the years with machines that left me prone to injuries that will never heal. I can’t say enough good about the product and firmly believe it deserves to be in every commercial and home gym in the world, it’s that good! Assembly was less than 10 minutes and came with all the hardware and tools needed to assemble the product. The directions were very simple and straightforward and the materials are commercial grade and would fit in nicely at public gyms that hunger for a piece of equipment like this.

Doug 5/5 Verified March 23, 2026

I really like this twister workout machine. It was easy to put together, doesn't take up much space, and gives me a good workout. It helps me stretch, twist, and get moving without putting too much strain on my body. It's a simple way to add some extra exercise to my day. would recommend it to anyone looking for an easy, low-impact workout machine.

Gen 5/5 Verified March 19, 2026

Cheap plastic item

Lourdes R. 3/5 Verified March 14, 2026

Ok. So, assembly first. The twist motion isn't as extreme as I expected ... which is a GREAT thing ... so I'm also getting the stomach crunch and slight midriff twist. I'm using this as part of a routine to become more flexible.So far, I'm happy with this item.

Freyasmom 4/5 Verified March 14, 2026

I loved working so good I almost finish with my project

Miguel A. 5/5 Verified March 11, 2026

I’ve been using this and stretch trainer for a while now, and it’s a great addition to my home workout routine. What really stands out is how it combines low-impact cardio with full-body movement. It engages multiple muscle groups at once, especially the core, back, arms, and legs, making workouts feel efficient without putting too much stress on the joints.The motion feels smooth and natural, almost like a guided crawling and twisting exercise, which helps improve flexibility and mobility over time. It’s especially nice for days when I want something effective but not too intense. I’ve noticed it helps with posture and reduces stiffness, particularly in the lower back area.The adjustable hand grips and knee supports make it comfortable to use for different body types. I appreciate that I can customize the setup to fit my height and preferred workout style. The padding on the knees adds extra comfort, allowing for longer sessions without discomfort.The steel frame feels solid and stable during use, giving confidence that it’s built to last. It doesn’t wobble, even during more active movements. At the same time, it’s compact enough to fit in a home gym space without taking up too much room.Overall, this is a versatile and beginner-friendly piece of equipment that offers a low-impact yet effective workout. It’s a great choice for anyone looking to improve strength, flexibility, and overall fitness from the comfort of home.

Thesmartselection 5/5 March 9, 2026

I was really excited to get this because it combines stretching and exercise in one piece of equipment. On my days off, I know I need to stay active, but it’s easy to lose motivation. Having something like this at home makes it much easier to get moving without committing to a full workout.I like that it works multiple muscle groups while also encouraging a good stretch, especially after long days of physical work. The padded knee supports are comfortable, and the machine feels sturdy while using it. It doesn’t take up much space either, which is a big plus if you don’t have a dedicated home gym.I’m looking forward to making this part of my routine because it feels like a fun way to stay active and loosen up on my rest days. If you’re looking for a low-impact piece of equipment that encourages both movement and stretching, this is definitely worth checking out.

Blake S. 5/5 Verified February 28, 2026

This crawler machine is a great way to switch up your workouts without putting a lot of stress on your joints. It gives you a full-body workout by engaging your core, arms, legs, and back, and I like that the adjustable hand grips make it comfortable for different users. The frame feels sturdy and the knee pads provide good enough cushioning. It also doesn’t take up as much space but I have it in the living room as larger cardio equipment-making it a nice fit for a home gym. It feels well built and offers a challenging low impact workout. It is a fun alternative to the usual treadmill or exercise bike. Good value, quality and it’s very sturdy.

Greenlights 5/5 Verified February 27, 2026

Lower back pain was unbearable. I got the castle flex stretcher. A month ago. Which helped a little. I was at the point of scheduling a chiropractor for help. When I saw this equip like a month ago. Issue was maximum weight capacity on 1st 5 models only being 220 lb. The moment I saw this would accommodate my 250lbs I immediately bought this. Back pain is Gone. Gone. Gone. If I lose pounds this is the icying on the cake. I have my life again WITHOUT SURGERY 🙏🏾🙏🏾🙏🏾🙏🏾Wish I would have got this years ago. It’s only been 4 days. My entire core is 100% improved.
