Ankle Weights Are the Key to Firing Up Your Abs—These Are the 8 Best Exercises to Do

Having a stronger core helps improve your posture, balance, and stability, according to Harvard Health Publishing. Working on your core strength can also make daily activities, like bending down to tie your shoes or sitting in your desk chair, that much easier.

Below, you'll find the best ankle weight exercises that'll isolate your abs and help build a solid core. Think of these moves as the cherry on top of your strength routine.

But first, the benefits of using ankle weights for ab exercises

1. It adds an extra challenge to your core

"Light ankle weights challenge the core by adding extra weight for the muscles of your core to brace against," Phillips says. With more weight on your legs, you'll have added resistance on your core muscles, which increases the demand on both your abdominals and stabilizing muscles. That translates to stronger core muscles over time as you continue using ankle weights in your ab routine and building strength.

2. You'll get a more intense workout

Really focusing on the muscles you're trying to activate while performing the movements helps you maintain good form. That's the whole point of the mind-muscle connection—it helps maximize the intensity of each move.

"Adding extra weight to the ankles challenges you to slow down against the added resistance, making each move more deliberate and intense," Phillips says.

3. It can help engage other muscles

Not only can ankle weights fire up your core, but wrapping these wearable weights can also help strengthen other muscles. "Ankle weights also help strengthen the accessory muscles being worked, such as the hip flexors and glutes, during your ab routine," Phillips says.

Tips for choosing ankle weights

1. Make sure they fit correctly

When shopping for a pair of ankle weights, comfort is key. "You'll want a pair that fits snugly around your ankle and will stay secure during your workout," Phillips says. "It's important that they fit well or are adjustable as ankle weights can stretch out over time."

2. Choose a light weight to start

If you're new to using ankle weights, choosing a pair that's one to two pounds is a good place to start. "I wouldn't go above three pounds, as too much of a load can cause you to bypass the deep muscles of your core and rely on other muscles, such as quads and hip flexors," Phillips says.

So if you're a beginner and your goal is to target your abs, aim for a pair that's one or two pounds. If you have more experience with strength training, you can grab a pair that's three pounds for a bit of extra resistance.

3. Consider adjustable weights

Some ankle weights come with adjustable weights, which allow you to add or remove some weight. "This gives you more versatility depending on the day or exercise," Phillips says.

Ankle weights generally range from one to three pounds, but they can go as high as 10 pounds. If you're planning to use the ankle weights for more than just ab exercises, consider opting for a pair with adjustable weights.
