TikTok generally is a fount of inspiration for the whole lot from DIY residence initiatives and recipes to helpful hacks and exercise ideas. The one drawback? As a result of each amateurs and professionals have equal entry to sharing their “experience” on the platform—and who is aware of how the algorithms assist a video go viral—it may be tough to separate out the useful from the dangerous.
So after we got here throughout a backward strolling treadmill exercise by TikTok consumer @samanthafit_ish, whose actual identify is Samantha Kunes, we had to take a look at whether or not it might truly assist with knee power, because the video claims.
Does strolling backwards actually do something to assist your knees?
The excellent news: Bodily therapist and founding father of HolisticDPT, Eni Kadar, DPT, CHN, Cert. DN, says that Kunes is perhaps onto one thing.
“A number of of essentially the most notable advantages of strolling backwards on a treadmill (retrograde strolling) are a rise in quad activation, and elevated knee extension vary of movement in comparison with ahead strolling,” says Dr. Kadar. “It could actually additionally help with rising decrease extremity power, practical mobility, and gait mechanics after an damage.”
Actually, one examine discovered that, in contrast with strolling ahead, strolling backwards on a treadmill induced extra vital enhancements in knee ache and quadriceps power after six weeks in folks with osteoarthritis.

Dr. Kadar says that the variations within the biomechanics are what makes strolling backwards extra helpful to the knees. “With forwards strolling, you might be advancing one leg at a time, touchdown in your heel and rolling off your toe. In the course of the swing section of gait, your knee is bent and your toes are lifted up in the direction of your shin,” she says. To manage these motions, the quadriceps and hip flexors contract concentrically (shortening) to advance the leg and the glutes and hamstrings contract eccentrically (lengthening) to manage the touchdown.
Nevertheless, these muscle contractions can doubtlessly elicit knee ache.
“The concentric contraction of the quads and hip flexors, together with immobility of the hamstrings, typically is what causes knee discomfort for folks as a consequence of muscle imbalances and undue strain on the constructions,” explains Dr. Kadar.
However altering the motion path adjustments the muscle activation. “In retrograde strolling, you might be touchdown in your toe first after which rolling off your heel,” she says. “Retrograde strolling requires extra hip and knee extension to happen in the course of the stance section and extra knee flexion if you attain again to take steps.”
While you stroll backwards, the identical muscle teams are concerned, however their actions are reversed: The quadriceps and hip flexors lengthen, whereas the glutes and hamstrings shorten. This will put much less stress and compressive drive on the knees.
So how does this lower knee ache?
Dr. Kadar says that many individuals with knee ache have restricted vary of movement within the knees, which may compromise regular strolling patterns and may trigger discomfort.
Backward strolling may also help restore some mobility. “The repetitive and low-intensity nature of strolling backwards can enhance knee extension for folks with out placing loads of drive or stress by means of the joint so it may be extra comfy,” Dr. Kadar says. “When you’re strolling backwards, you might be required to increase your knee greater than in case you had been going forwards. The quadriceps is answerable for extension of the knee and power of this muscle is vital to handle and forestall knee ache, particularly in populations with osteoarthritis.”
She believes that backwards strolling on a treadmill generally is a welcome boost to different strengthening packages to enhance knee mobility, power, and performance. Plus, she says it might probably enhance hamstring flexibility, a standard drawback amongst these with knee ache.
How you can safely stroll backwards on a treadmill
You possibly can incorporate backwards strolling into your exercises as a warmup, cooldown, or perhaps a standalone exercise. But it surely would possibly really feel awkward at first. Dr. Kadar shares a number of recommendations on the best way to do it safely:
- Begin with a slower velocity (1 to 2 mph) and maintain onto the handrails for steadiness. You possibly can allow them to go when you get extra comfy.
- Use the security key by attaching the lanyard to your shirt at hip top. This may routinely cease the belt in case you get too removed from the console.
- Start with 5 to 10 minutes and steadily construct up as your endurance improves.
- Consider reaching again along with your leg, touchdown in your toe and rolling by means of to your heel earlier than selecting up your different leg.
- Give attention to taking even steps, conserving your step size the identical on each side.
- Interact your core muscular tissues and keep as upright as doable, avoiding the tendency to lean forwards.
- Add a slight incline as you get stronger to reap further advantages.
- When you have poor steadiness or are uncertain, ask for assist from a certified coach to keep away from damage.
However don’t neglect ahead strolling, or different power exercises. “We do not stroll round backwards all through the day (hopefully)!” Dr. Kadar notes. “Reverse strolling is a great tool, however I do not contemplate it a alternative to a correctly structured strengthening program. And at all times hearken to your physique and do not push by means of something that does not really feel proper.”
