Exercises with dumbbells: 8 best moves to tone arms

Strengthen and tone your arms to perform daily activities with ease. All you have to do is incorporate these arm exercises with dumbbells in your workout routine.

Toning your arms may be one of your aesthetic goals. But you should not aim to have toned and strong arms just because they look good. They are essential in making daily tasks like lifting and carrying things easier. Even reaching the top shelf needs the help of well-defined arms. To gain them, you need to sweat it out. If you already have a fitness routine, add arm exercises with dumbbells to it. At most gyms, you will find many fixed dumbbells of varying weights. If working out at home is more your style then go for adjustable dumbbells. Having this type of dumbbell means you can add or remove the weighted plates as per your requirement.

Arm exercises with dumbbells: How it helps?

Maintaining arm strength and keeping them toned become increasingly important as we age. “Starting around age 35, muscle endurance and strength naturally begin to decline by about 1 percent each year. This gradual loss of muscle can result in decreased endurance, strength, limited range of motion and a higher risk of injury,” says physiotherapist and fitness expert Dr Aijaz Ashai.

To build and maintain muscle mass as well as strength, the US Centers for Disease Control and Prevention recommends two days of muscle-strengthening activities every week. “Doing arm exercises can preserve strength, promote healthy movements, improve balance, and prevent injuries,” says the expert.

Dumbbells are a versatile tool for strengthening and toning arms. During a 2020 study published in Frontiers, dumbbell exercises led to a high level of muscle activation in the upper arm of participants. Here’s how dumbbells help build strong and toned arms:

  • Dumbbells provide resistance that challenges your muscles, encouraging growth and strength over time.
  • With dumbbells, you can perform a wide range of exercises, which target different key muscles in the upper body, including biceps, and triceps.
  • Dumbbells allow for one-sided exercises, helping correct muscle imbalances and ensuring both arms are equally strong.
  • Increasing dumbbell weight over time promotes muscle growth and strength.
  • Dumbbells allow a great range of motion, ensuring full muscle activation.

8 effective arm exercises with dumbbells

1. Bicep curl

  • To do bicep curl that targets biceps, stand with dumbbells at your sides, with your palms facing forward.
  • Curl the dumbbells up towards your shoulders.
  • Lower them down slowly.

2. Hammer curl

  • Hold the dumbbells with your palms facing one another.
  • Bend your elbow to lift the weights targeting your forearms and biceps, and neutralise your wrists.
  • Bring them down after a few seconds.

3. Tricep kickback

  • Hold dumbbells in your hand with your palms facing each other, and keeping your knees little bent.
  • Maintain a straight spine as you hinge forward at your waist.
  • Bring your chest almost parallel to the ground.
  • Keep your upper arms closer to your body with your head in line with your straight spine.
  • Engage your triceps by keeping your elbows straight.
  • Keep your upper arms still, and move just your forearms.
  • Pause then return the weights to the first step.

4. Military press

  • Make sure your palms are facing forward, as you hold a dumbbell above each shoulder.
  • Press the dumbbells up, with the weights above your head, and your elbows bent a little bit.
  • Hold the equipment above your head for a moment.
  • Slowly lower the dumbbells back.

5. Lateral raise

  • Stand with two dumbbells at your sides to target your shoulders.
  • Raise your arms to shoulder height, where they form a “T” shape.
  • Lower back to starting position very slowly.

6. Front raise

  • Hold dumbbells in front of your thighs, and your palms facing down.
  • Raise one dumbbell straight in front up to shoulder height.
  • Follow the same steps using the other dumbbell then lower down.

7. Concentration curl

  • Sit with dumbbells in each hand. Place the elbow of your arm you are holding the dumbbell onto on the inner thigh of your other leg.
  • Focusing on your biceps, curl up and down on the dumbbell.
  • Lean forward with dumbbells, and bend your elbows to 90 degrees
  • Extend your arms behind you until they are straight.
  • Go back to the starting point.

8. Dumbbell pullover

  • Raise your arms with dumbbells toward the ceiling with your palms facing each other, and elbows slightly bent.

Arm exercises with dumbbells: Some tips to keep in mind

“While starting with arm exercises with dumbbells, aim for maximum repetitions with minimal weight. You can do three sets of 12 to 15 reps to help build endurance in your muscle fibers,” says Dr Ashai. Once you reach the endurance level, shift focus to strengthening your arm muscles, which will allow them to maintain strength for longer periods.

The weight of the dumbbell depends on the level of fitness among women. “Newcomers can start with 3 to 5 lbs, as light dumbbells will help them focus on form rather than the weight,” says the expert. People who are accustomed to exercises require 5 to 10 lbs. An advanced fitness enthusiast can go for 10 to 15 lbs or higher to tone arms.

Arm exercises with dumbbells: Who should avoid?

  • People with injuries or limitations in the shoulder, elbow, or wrist area should not perform arm exercises with dumbbells without first clearing by a doctor or trainer.
  • Back pain or posture problems can make it difficult for some people to do standing exercises, so go for a seated alternative.
  • People with muscle pain should not lift weights.

You can incorporate arm exercises with dumbbells into a full-body workout. But listen to your body and rest if the muscles in your arms get sore. If you have any health conditions such as shoulder, elbow, or wrist injury, consult your doctor before starting these exercises.

Ditch sit-ups and crunches — this 5-move standing abs workout will help you build a stronger and more sculpted core

The beauty of a standing abs workout is that you do not need a mat, much space, or to get down on the ground for any of the exercises. That makes it easy to fit into a busy day, whether you are working out at home, short on space, or prefer to stay off the floor altogether.

None of that means it is easier or delivers fewer results. Pilates instructor and Balance Body Educator Portia Page built this five-move, all-standing core workout to show that you can still challenge your abs effectively without a mat or traditional floor exercises.

The future of fitness: How AI coaches are changing the way we exercise

Fitness and health apps have been promising “smart coaches” and “personalised training plans” for years. But, to date, most programmes have been like online shopping recommendations, with exercises broadly matching your demographic profile and performance level.

However, the rapid advances in real-time image recognition, generative AI and natural language processing are bringing an AI coach worthy of the name within our grasp. And not just for high-tech gyms like Lumin, but also for people working out at home or in the park. Peloton, for example, films how you exercise and provides feedback in real time. Google has also announced AI-powered personalised fitness and health advice for its Fitbit range.

Market analysts think the AI fitness market could be worth close to $35b USD by 2030. But how close are we to that future? Which company is training up the supertrainer? And how will that change the way we exercise, sweat and track our progress? And what do we need to know about this new world?

Confidence Udegbue has the perfect CV for designing an AI coach. The Vice President of Product at fitness app Freeletics studied electrical and computer engineering and teaches fitness classes in his free time. His broad shoulders, muscular biceps and infectious spirit are a dead giveaway: this guy knows what he’s talking about.

“In the gym, I can see immediately when someone I’m teaching is making a mistake,” says Udegbue. “But that expertise is hard to scale.” Freeletics is trying to solve that problem with AI. The app has been using a predictive algorithm since 2019 to suggest workouts based on demographic data and self-assessed fitness levels. This means that a 39-year-old man who has been training for two years and is at level 63 in the app won’t receive the same instructions as a 25-year-old beginner.

Freeletics uses AI-based motion analysis powered by models like those from Google’s MediaPipe framework, which includes BlazePose – the successor to the earlier PoseNet model. The models provide a skeletal muscle database that can replicate all types of exercises, for which Freeletics sports scientists then define the movements. That way, the system can assess whether that squat you just did went low enough.

Can an AI coach give useful real-time workout feedback?

In 2024, Freeletics introduced the Coach+ feature – an AI-powered chatbot with Freeletics expertise and access to anonymised data from over 59m user journeys. Users can ask the virtual coach questions like, “How can I build muscle mass?” or “I feel weak – how can I motivate myself?”

Freeletics is currently testing a version that will allow the app to see you work out. As of April, users have been able to record themselves exercising on their smartphones. “AI counts the reps and gives direct feedback,” Udegbue says. That is particularly helpful because even experienced athletes do not always perform pistol squats or burpees correctly.

Democratising the personal coach experience

A personal coach was long the preserve of Hollywood actors, top models and CEOs – a highly competent service provider, always available whenever a slot opened up in their client’s busy schedule. They know their clients’ allergies, preferences and weak spots. They always know how to set the pace. Sometimes they’re pushy, sometimes they go easy. They are a mix of therapist, personal assistant and best friend – open 24/7, all major credit cards accepted.

In the soccer world, the manager is often called “boss” – a figure of respect who takes care of the players both on and off the field. A good coach can tell when something is off in a movement – when the person’s mind is elsewhere, or they’re lacking energy. Anyone who has had that person in their life knows that a good coach is worth their weight in gold, which is why there are coaches for everything – careers, relationships, nutrition – and why the idea of a personalised fitness coach is so appealing.

AI has no body or talent. It doesn’t know what it feels like for sweat to run down the skin or for muscles to cramp or for adrenaline to rush through the veins. But it does recognise patterns and make predictions that we humans can use increasingly often and, in the best-case scenario, find out more about ourselves in the process.

Mirrors show you how you see yourself. But the Magic AI Mirror promises that you will like what you see if you follow the exercises and tips on the reflective screen. Behind the glass surface is an AI coach who steers your workouts in real time.

Growl goes even deeper into movement detection. The start-up has developed an exercise boxing bag that captures every movement with 3D cameras and Lidar (light detection and ranging) technology. AI corrects your posture or encourages you when your energy decreases.

Whoop’s fitness trackers combine biometric data with generative AI. If you’re wondering when you got your best sleep, you’ll get a precise answer: “On July 14, because the allergy season was over and you didn’t drink alcohol.” You can chat with your body.

Freeletics is also banking on predictive AI. “Soon the system will recognise that user X has had an increased resting heart rate for days, so I won’t suggest high-intensity exercises,” says Udegbue.

The vision all companies are working on is a multimodal coach: AI that unlocks information – biometrics, genetics, video, training history – and conveys it intuitively to the user. But a perfect coach is more than just an algorithm. Researchers are working on reinforcement learning systems that set individual step goals that are challenging but achievable, and adapt whenever progress has been made.

“We will not be able to deliver on the promise of absolute personalisation for the mass market,” Eskofier says. But before you lose hope, you should know what he means by personalisation.

His laboratory supports, among other people, Sebastian Steudtner, the big wave surfer and world record holder. To do this, they measured his body in an MRI scanner, carried out psychological assessments, calculated strength curves and even fitted his surfboard and wetsuit with sensors.

Eskofier’s team created Steudtner’s digital twin. By the time the project concluded in May 2025, their AI system could already discuss with a real coach what angle Steudtner should surf a 100-foot wave at, and whether he’d be strong enough to do it.

“We can’t offer that service to millions of people,” Eskofier says. “But these systems can still create real added value.” He believes AI coaches are a good base: “AI can take over data processing and routine personalisation, while real coaches can focus on mentoring.”

AI coaches are getting smarter all the time, too, which is why it’s important to know what they can and can’t do. Limited data sets can lead to bias if too few women or people of below-average height are represented in the data.

“No matter how good the technology gets, one thing will never change,” says Udegbue. “A coach can only make you better if you want to be better yourself, too.” It’s all in your hands.
