You’ve seen them in 1980s aerobics videos. Neon spandex, high-cut leotards, and those bulky, sand-filled straps wrapped around someone's limbs. For a long time, wrist and ankle weights were relegated to the "fitness fad" graveyard, right next to the Shake Weight and those vibrating belt machines. But honestly? They’re making a massive comeback. Walk through a park in any major city today and you’ll see people wearing sleek, silicone-coated bangles that look more like jewelry than gym equipment. Brands like Bala Bangles have basically rebranded resistance training for the "hot girl walk" generation.
It’s easy to dismiss them. People do. But there’s a real, science-backed reason why adding just one or two pounds to your extremities can actually change your metabolic profile.
It’s about leverage. Physics doesn't care if your weights are trendy or if they're dusty relics from your mom's garage. When you put a weight at the end of a long lever—which is exactly what your arm or leg is—the torque required to move that limb increases significantly. It turns a simple stroll into a weighted carry. It turns a Pilates session into a localized endurance test. But there is a right way to do this. And there is a very, very wrong way that ends with a physical therapist sighing while they look at your MRI.
The Science of Constant Resistance
Most people think of "lifting weights" as a discrete activity. You go to the rack, you do a set, you put it down. Wrist and ankle weights change the math because they provide passive resistance. This is what researchers call "non-exercise activity thermogenesis" or NEAT, but amplified. By wearing weights during daily chores or light movement, you are essentially increasing the energetic cost of existing.
A study published in the Journal of Taibah University Medical Sciences looked at the effects of wearing light weights (around 0.5kg) during daily activities. The results weren't world-shattering, but they were consistent: participants saw a modest increase in heart rate and oxygen consumption. It’s not going to turn you into a bodybuilder. It will, however, nudge your caloric burn upward without you having to schedule an extra hour at the HIIT studio.
Why Your Joints Might Hate You
We need to talk about the "walking with ankle weights" controversy. If you ask a podiatrist or an orthopedic surgeon about wearing three-pound weights on your ankles for a five-mile run, they might actually cringe.

Here’s why: your gait.
When you add weight to your ankles, you’re changing your center of gravity and the way your muscles fire to swing your leg forward. This puts an abnormal amount of stress on the hip flexors and the anterior tibialis. Over time, this can lead to repetitive strain injuries or even exacerbate lower back pain. You're basically asking your joints to act as brakes for a heavier load they weren't designed to swing.
If you're going to use them for cardio, keep it light. Really light. We're talking one pound. Maybe two if you’re already quite strong. Anything more than that during high-impact movement is just asking for a tendonitis flare-up.
Wrist Weights and Upper Body Toning
Wrist weights are a slightly different beast. They’re fantastic for people who find holding dumbbells uncomfortable—maybe due to arthritis or grip strength issues. Because the weight is strapped to the wrist, the resistance is distributed differently.
Think about a shadowboxing workout.
If you hold a three-pound dumbbell, your grip is doing a lot of the work. If you strap those three pounds to your wrists, your shoulders, deltoids, and triceps take the brunt of the load. It allows for a more fluid range of motion. You can do yoga, arm circles, or even just fold laundry while wearing them.
- Pros: Increases caloric burn during aerobic activity; improves bone density (gravity is your friend here); helps with muscle endurance.
- Cons: Can lead to elbow or shoulder strain if used with jerky movements; easy to overdo; doesn't replace heavy resistance training for hypertrophy.
I’ve found that the best use case for wrist weights isn't actually the gym. It’s the "in-between" moments. Putting them on for a 20-minute walk to the coffee shop provides a subtle "pump" that makes you feel more engaged with your body. It’s a psychological win as much as a physical one.
The Hypertrophy Myth
Let’s be real for a second. You aren't going to get "jacked" using ankle weights.
If your goal is to grow significant muscle mass (hypertrophy), you need progressive overload. That means lifting heavier and heavier things over time. Most ankle weights max out at about 5 or 10 pounds. While that's heavy for a leg lift, it's not enough to stimulate the kind of muscle tears required for big growth in the glutes or quads.
However, they are elite for muscle endurance.
If you’re doing floor-based Pilates—think side-lying leg raises or "clamshells"—adding a two-pound ankle weight feels like someone turned the gravity up by 300%. It targets those smaller stabilizer muscles like the gluteus medius, which are notoriously hard to hit with traditional squats and deadlifts. This is where the value lies. It’s about the "burn," not the "bulk."
Choosing the Right Gear
Don't just buy the cheapest ones you find on an end-cap at a big-box store. Cheap weights use low-quality sand that shifts around, making them feel unbalanced and clunky. They also tend to use scratchy velcro that will cheese-grate your skin after ten minutes of sweating.

Look for:
- Silicone or Neoprene coating: This stays put and doesn't absorb sweat (and the subsequent smell).
- Adjustability: Some weights allow you to add or remove small iron slugs. This is great for progressing.
- Secure Strapping: If it wobbles, it’s going to cause a blister. Period.
Brands like Bala are famous because they look good, but Sportneer or REEVOO often offer more weight for less money if you don't care about the aesthetic. Personally, I prefer the ones with individual weight pockets. It's more versatile. You can start with one pound and work your way up as your tendons get used to the load.
The Bone Density Factor
One of the most overlooked benefits of wrist and ankle weights is their impact on bone health. This is especially crucial for women and older adults. Osteopenia and osteoporosis are real risks as we age. Weight-bearing exercise is the primary non-pharmaceutical way to fight this.
By adding even a small amount of weight to your limbs, you are increasing the "load" on your bones. This stimulates osteoblasts—the cells that build bone. It’s a low-impact way to maintain skeletal integrity. It’s much safer for an 85-year-old to walk with one-pound wrist weights than to try a heavy bench press.
Practical Ways to Incorporate Them
Stop thinking of these as "workout gear" and start thinking of them as "resistance accessories."
If you’re doing a barre class, they’re perfect.
If you’re doing a slow, controlled Vinyasa flow, they add a nice challenge.
If you’re power-walking? Maybe skip the ankles and stick to the wrists to protect your knees.
A specific routine to try:
Next time you’re doing a core workout—dead bugs, bird-dogs, or mountain climbers—strap on the weights. The added weight on your feet makes your lower abs work twice as hard to stabilize your pelvis. It turns a standard core move into a full-body stabilization challenge.
But please, for the love of your joints, don't wear them all day. Your body needs "off" time. Constant loading can lead to postural issues because your muscles never get a chance to relax into their natural alignment. Treat them like a tool, not an outfit.
The Verdict on Wrist and Ankle Weights
They aren't a miracle. They won't burn off a pizza in ten minutes. But they are a remarkably effective way to increase the intensity of low-impact movement. In a world where we spend most of our time sitting, any tool that makes movement more "expensive" for the body is a win.
Just be smart. Start lighter than you think you need to. Focus on slow, controlled movements rather than fast, swinging ones. Your tendons will thank you, and you’ll actually see the results in your muscle tone and endurance.
Actionable Next Steps:
- Audit your movement: Identify one 20-minute window in your day where you are moving but not "exercising"—like walking the dog or doing light housework.
- Start at the bottom: Purchase a pair of 1-pound weights. If you can't feel them, do more reps rather than buying heavier weights immediately.
- Test your gait: Put the weights on and walk in front of a mirror. If you notice your feet "slapping" the ground or your hips swaying more than usual, take them off. Your form is more important than the extra calories.
- Target the stabilizers: Use ankle weights specifically for lateral (side-to-side) movements to strengthen the muscles that protect your knees.
- Clean them: If you buy fabric-based weights, hand-wash them once a week. They trap bacteria faster than a gym towel.
