The Horse Riding Exercise Machine: A Bicycle Seat on Rocking Legs That Produces the Most Suggestive Motion in Fitness History
Someone built an indoor saddle that bucks and rocks while you straddle it, called it 'exercise,' and hoped nobody would notice what it looks like

I thought the Shake Weight had a monopoly on "exercise equipment that looks like something else entirely." I was wrong. The horse riding exercise machine exists, and it makes the Shake Weight look subtle.
The device is a padded saddle mounted on a mechanical base with articulated legs or a rocking mechanism. You sit on it. It moves. You move with it. The motion is a rhythmic, forward-and-back rocking that engages your core, allegedly, and your sense of dignity, not at all. The marketing claims you'll burn calories and tone your abs while simulating horseback riding from the comfort of your living room.
What the marketing doesn't mention — because the marketing is desperately hoping you won't notice — is that the motion of sitting on a rocking saddle and moving your hips rhythmically forward and backward looks exactly like what it looks like. There is no innocent angle. There is no camera position from which this device appears to be simply exercise equipment. From every direction, at every speed, on every user, this machine produces a visual that is, at minimum, deeply inappropriate for an open-plan office and, at maximum, something you'd need to explain to a roommate who walks in unannounced.
The Shake Weight's infomercial looked suggestive by accident. The horse riding exercise machine's infomercial looks suggestive by physics. The motion IS the motion. The product cannot be redesigned to not look like this. The only way to make a rocking saddle not look suggestive is to not make a rocking saddle.
The Vision: Equestrian Fitness, Minus the Horse and the Fitness
The concept originates from a kernel of legitimate science: horseback riding does engage core muscles. Maintaining balance on a moving horse requires continuous core stabilization, hip flexibility, and lower-body isometric engagement. Riders who spend hours in the saddle do develop core strength.
The horse riding exercise machine takes this observation and extracts from it the least useful component: the sitting-on-something-that-moves part. It removes the horse. It removes the outdoors. It removes the 1,200-pound animal that creates the actual instability you're responding to. What remains is a motorized seat that rocks you gently back and forth while you sit in your living room watching television, burning approximately the same number of calories as sitting in a recliner that has a vibration setting.
The machines typically offer adjustable speed — from "gentle rocking" to "rodeo" — and are available in price ranges from $100 for an Amazon knockoff to $600+ for commercial-grade units. Some come with handlebars. Some come with digital displays showing calories burned. All of them come with the unspoken understanding that using one in front of other humans requires either extreme confidence or a complete absence of self-awareness.
The Glorious User Experience
Rachel from Houston, TX — ★☆☆☆☆
"My husband bought this for me as a birthday gift, which should have been grounds for divorce. He set it up in the living room. I sat on it. It started rocking. My 14-year-old son walked in, looked at me, turned around, and walked out without saying a word. He did not speak to me for the rest of the evening. The horse riding exercise machine ruined a birthday and a parent-child relationship in the same afternoon. One star."
Steve from Atlanta, GA — ★☆☆☆☆
"I tried this at a fitness expo. In public. Surrounded by hundreds of people. The salesperson said, 'Just sit on it and let the motion do the work!' I sat on it. The motion did its work. A group of college students started filming. I dismounted in approximately four seconds, which is the fastest I've moved at a fitness expo and therefore the most effective exercise the machine provided. One star."
Karen from Sacramento, CA — ★☆☆☆☆
“The device is a padded saddle mounted on a mechanical base with articulated legs or a rocking mechanism”
Click to Tweet"I used the machine at the lowest speed for twenty minutes. My core did not feel engaged. My abs did not feel activated. What I felt was: gently rocked. Like an adult-sized baby in a mechanical cradle that I was straddling. The experience was not exercise. It was a weird nap with hip movement. I burned more calories carrying the machine to the curb than I did riding it."
Anonymous Amazon Reviewer — ★★☆☆☆
"Two stars because the rocking motion is genuinely relaxing, but I am not going to admit what it looks like to anyone, and if you purchase this product you should also purchase curtains. Thick curtains."
The Truth: No Horse, No Evidence, No Dignity
No peer-reviewed study has demonstrated that motorized rocking saddle machines produce meaningful fitness outcomes. The caloric expenditure from sitting on a rocking machine is negligible — a 2014 study on oscillating platforms (a related concept) found that passive whole-body vibration burned approximately 3-5 calories per minute above resting, which means a 20-minute session on the horse riding machine burns roughly the caloric equivalent of half an apple.
For context, walking burns 4-5 calories per minute. A rowing machine burns 8-12. A Peloton bike burns 10-15. The horse riding exercise machine burns fewer calories per minute than walking, while requiring a $200-600 purchase and the willingness to be perceived by other humans.
Actual horseback riding, by contrast, burns 5-8 calories per minute and provides genuine core stabilization, hip mobility, and cardiovascular challenge. It also involves a horse, which is the part the machine removed and which, coincidentally, is the part that made the exercise work.
The machine persists on Amazon, where it exists in a category of products that could charitably be called "fitness" and uncharitably be called "electric furniture for adults who enjoy rocking." Reviews are mixed between people who genuinely use it for mobility and people who purchased it expecting fitness results and received a rocking saddle.
The Verdict
The horse riding exercise machine is the logical conclusion of the fitness industry's obsession with removing effort from exercise. It took the one legitimate element of horseback riding — the physical challenge of staying balanced on a moving animal — and replaced the animal with a motor and the challenge with gentle rocking. What remains is a saddle that rocks you back and forth while you burn fewer calories than walking, for hundreds of dollars, while producing a visual that requires curtains.
The Shake Weight was suggestive by accident. The horse riding machine is suggestive by design. There is no version of straddling a rocking saddle that doesn't look like what it looks like. The product is what it is. And what it is, is not exercise.
We rate it 1 out of 5 closed curtains.
