Eccentric exercise: A way to get stronger and improve heart health

Eccentric exercise may help to improve your strength, and boost heart health. Here are a few examples that should be part of your fitness training.

Weight loss isn’t the only reason why many of us exercise. For many people, the aim may be to build strength, and simply be healthy. There are many techniques that can help you meet your fitness goals. One example of this is eccentric exercise. This involves gradually lowering weight while maintaining control. It is a popular technique in the fitness world, as it can help to improve physical strength, and lead to muscle growth. It may also enhance flexibility, and improve your heart health. If you are a fitness enthusiast then you are probably already doing this exercise. However, it is not limited to gym enthusiasts, as people of all fitness levels can try it.

What is eccentric exercise?

Eccentric exercise is a strength training technique that is often used while working out. It focuses on active lengthening of muscles under tension, according to research published in Nutrition and Enhanced Sports Performance in 2019. It happens when you lower a weight or control a movement against resistance, such as during the downward phase of a squat or push-up.

“This type of exercise focuses on slowing down the negative or lowering phase of a movement, which builds strength and control,” explains fitness expert Abhi Singh Thakur.

What are the benefits of eccentric exercise?

Before learning how to include it in your fitness routine, know the benefits of eccentric exercise:

  • Increased muscle strength: Eccentric exercise is great for improving strength. It can improve muscle strength and power in healthy people, according to research published in Sports Medicine in 2013. It creates tension in the muscles that leads to strength gains.
  • Improved coordination: “Controlling the lengthening phase improves stability and coordination,” says the expert. This is especially important in sports or daily activities where you need to control your body under different conditions.
  • Enhanced flexibility: Since the muscles stretch while under load, eccentric exercise can increase flexibility and reduce stiffness over time. For example, lowering into a deep squat can improve hip and hamstring mobility.
  • Injury prevention: By strengthening muscles and tendons through their full range of motion, eccentric training helps to protect joints and connective tissues from injuries, especially during high-impact movements.
  • Better muscle growth (Hypertrophy): During the eccentric phase, your muscles work harder to resist the weight or control movement. “This generates high levels of mechanical stress, leading to microscopic tears in the muscle fibers,” shares the expert. When muscle fibers experience these microscopic tears, your body triggers a healing response where muscle stem cells activate. These cells repair and rebuild the damaged fibers, making them thicker and stronger.
  • May be good for the heart: Eccentric exercise may help to keep your heart strong. A 2023 study, published in the Journal Of Sports Science & Medicine, showed that eccentric exercise improved health-related risk factors such as lipid profiles and reduced heart rate, and blood pressure.

6 best eccentric exercises

Here are some of the best eccentric exercises to do regularly.

1. Eccentric squats

  • To do eccentric squats, start by standing with feet shoulder-width apart.
  • Slowly lower your hips back and down for 4 to 6 seconds, keeping your knees in line with your toes.
  • Pause at the bottom, then rise back up normally.

2. Eccentric push-ups

  • Begin in a plank position with your hands under your shoulders.
  • Lower your chest to the floor slowly (4 to 6 seconds), keeping your core tight.
  • Push back up quickly to the starting position.

3. Eccentric pull-ups

  • Start at the top of the bar with your chin above it (use a box if needed).
  • Slowly lower yourself down over 4–6 seconds until arms are fully extended.
  • Reset and repeat the steps.

4. Eccentric deadlifts

  • To do eccentric deadlifts, start by standing with the barbell or dumbbells at thigh level.
  • Lower the weights slowly while keeping your back straight and core engaged.
  • Stop when the bar reaches shin level, then return to standing normally.

5. Eccentric step-downs

  • Stand on a step or box with one foot hanging off.
  • Slowly lower your other foot to the floor over 4–6 seconds.
  • Return to the starting position and repeat.

6. Eccentric calf raises

  • Stand on the edge of a step with your heels hanging off.
  • Raise up onto your toes, then lower your heels down slowly over 4–6 seconds.

Common mistakes to avoid while doing eccentric exercise

Eccentric exercise may look simple, but people tend to make mistakes. Here are some of the mistakes to avoid while doing it:

  • Rushing through the movement: Eccentric exercise is about controlled lowering. “So avoid dropping the weight or rushing the negative phase,” says Thakur.
  • Using excess weight: Too much weight can compromise form and increase injury risk. Start light and focus on control. If you are a beginner, and using dumbbells, go for 5 kg.
  • Neglecting range of motion: Not using the full range can limit the benefits of eccentric exercise. Ensure you lower the weight completely.
  • Ignoring warm-up: Jumping into eccentric training without warming up increases injury risk, so always prep your muscles beforehand.
  • Overtraining: Eccentric movements are intense, and so, doing too much can cause extreme soreness or injuries.

Who should avoid eccentric exercise?

It can be done by various people, but some people need to be cautious or simply avoid it.

  • People recovering from severe injuries or surgeries should not do this type of exercise. “Eccentric movements place significant stress on muscles, tendons, and joints, which can aggravate existing injuries or slow down recovery,” says the expert.
  • Eccentric exercise can feel too demanding for those new to fitness. Beginners should not do it on their own, as they need proper guidance.
  • People with joint or tendon issues should skip it. “Conditions like arthritis or tendonitis can worsen because eccentric exercise exerts high mechanical stress on these structures, leading to further inflammation or pain,” says Thakur.
  • People experiencing extreme muscle soreness should avoid it. “If you are already experiencing delayed onset muscle soreness from a previous workout, adding more eccentric stress can exacerbate discomfort and prolong recovery,” says the expert.

Eccentric exercise can help to build strength, improve flexibility, and coordination. It can be beneficial for people with different fitness levels, but make sure to do it under proper guidance, especially beginners.

Related FAQs

Is walking an eccentric exercise?

Walking is not fully eccentric but does involve eccentric components. For example, your quadriceps lengthen while controlling the impact as your foot strikes the ground. However, walking is not intense enough to count as a true eccentric workout.

Can seniors do eccentric exercise?

Yes, seniors can do eccentric exercise, but with caution. The exercise helps to improve strength, balance, and mobility, which are crucial for ageing. However, start with bodyweight or light resistance, focus on form and slow movements.

What is the difference between eccentric and concentric exercise?

In eccentric exercise, the muscle lengthens under tension (e.g., lowering a dumbbell in a bicep curl). In concentric exercise, the muscle shortens while contracting (e.g., lifting a dumbbell in a bicep curl).

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.

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.
