Include these 8 isotonic exercises to improve strength and flexibility
Isotonic exercise is a form of strength training that is beneficial for those looking to build muscle and lose weight. Exercises like lunges, and squats come under this type of training.
If you enjoy working out, your fitness routine probably includes exercises like squats, lunges, and push-ups. These are all examples of isotonic exercise, a form of strength training in which the muscles are required to resist weight over a range of motion. This type of training is not only good for improving physical strength, but also for flexibility, and balance. It is also an effective way to burn calories and get rid of extra body fat. As you explore the benefits of isotonic exercise, know which moves you can include in your fitness regime.
What is the isotonic exercise?
It is categorised as exercise which involves the contraction and shortening of muscles through a variety of movements, including those of the joint. “During this type of training, the body’s muscles change their length as per the movement to create and support joint movement with constant load or weight,” says fitness expert Aman Puri. This type of exercise overcomes resistance, where the body’s muscles keep a consistent level of tension or load during that movement.
It usually includes exercises like push-ups, and running or even everyday tasks like cleaning, or carrying groceries. Isotonic exercise can also be performed with equipment involving weightlifting machines, dumbbells and resistance bands.
What are the benefits of doing isotonic exercise?
1. Strengthens muscle and endurance
This type of exercise increases muscular strength and challenges muscles by focusing on repetitive movements that enhance endurance and improve overall strength. “In isotonic exercise, the muscles relax and contract through different range of motions, gaining more ability to handle repetitive and sustained movements,” says the expert. Isotonic exercise can improve muscle tone, increase physical power, and help build muscles, as per research published in Healthcare in 2022.
2. Improves flexibility and joint mobility
Isotonic exercise includes motions from a diverse range of movements, so it enhances flexibility and improves the mobility of joints. During a 2022 study, published in Applied Sciences, isotonic exercise was found to be effective in improving flexibility.
3. Promotes blood circulation
Isotonic exercise like running which involves dynamic and repetitive movements promotes cardiovascular health. “It enhances blood circulation and oxygenation, which can boost heart health. The pumping of the blood may also reduce the chances of stroke,” says Puri.
4. Enhances balance and coordination
In this type of exercise, muscles are worked upon in a controlled and repetitive manner, which improves neuromuscular control. “This controlled movement leads to balanced and better coordination by improving and stabilising muscles, flexing up the joints improving overall body movement,” says the expert

5. Helps manage weight
It helps improve metabolism and promote fat burning as they involve several muscle groups and require repetitive activity which helps burn more calories. Squat, a popular move, is an example of isotonic exercise. During a 2013 study, published in the Journal Of Sports Science And Medicine, researchers found that squat training significantly decreased body fat and increased the lean body mass in participants.
What is the difference between isometric and isotonic exercises?
- It may be beneficial for strengthening muscle mass and improving power and endurance. “On the other hand, isometric exercise may be beneficial for toning or for those recovering from injuries as it does not involve loading the muscles or increasing muscle tension,” says the expert.
- While performing isotonic exercise, the muscle length is shortened with constant tension or weight. On the other hand, while performing isometric exercise, the muscle length does not change as tension increases.
- Also, isotonic exercises involve joint movement whereas isometric exercises do not involve any joint movement.
What are the examples of isotonic exercise?
1. Lunges
- Take a step forward with one of your legs then gradually lower your hip with both your knees bent around 90 degree.
- Push your body through the front foot to go back to the starting position and do it again with your other leg.
2. Squats
- Stand up on your feet apart aligned with the shoulder-width.
- Bend your knee, lowering your hips and keeping your back in a straight position.
- Continue lowering your hips down till your thighs become parallel to the floor.
- Push up your body by returning back to a standing position while straightening your knees.

3. Push-ups
- To perform push-ups, start with the position of the plank. Place your hands a little wider apart from shoulder width.
- Lower your body down by bending both your elbows reaching lower till your chest is near the ground level.
- Push up your body back keeping your back straight.
- Straighten your elbows as you push up your body and go back to the starting position.
4. Kettlebell swings
- In this isotonic exercise, first hold the kettlebell weight with both your hands and then stand by keeping your feet shoulder-width apart.
- Gradually bend your knees and swing back the kettlebell between both your legs, moving your hips forward trying to swing the kettlebell upto your chest level.
5. Leg press
- It is performed with the leg press machine. Sit by placing your feet shoulder-width apart on the machine’s platform.
- Extend your legs upwards, pushing the platform upwards.
- Gradually bend your legs back, lowering the weight down.

6. Jumping jacks
- Jumping jacks do not require any equipment. You just need to simply stand with arms straight.
- Start jumping while extending the feet apart and raising both your arms overhead in alternate movement.
- Jump back again to return back to the straight position.
7. Deadlift
- To carry out this exercise, stand with your feet and hips aligned to the same width.
- Grip the barbell with both hands in front of your thighs and start lifting the barbell while bending your knees, and lowering your hips.
- Lift the weight holding the barbell and then lower the barbell back to the ground keeping your back straight.
- After that return to the standing position, straightening the knees and hips.
8. Mountain climber exercise
- Start in a plank posture with your arms straight on the ground position and extending your legs backwards supported by your toes.
- Bring your knees in forward direction near the chest, and switch legs alternately.
Who should avoid doing isotonic exercise?
“Everyone can perform some form of isotonic exercise regularly,” says Puri.
- Since isotonic exercise also involves weights, those with sprains, muscle tears or bone injuries involving fractures and dislocation should avoid performing an intensive form as it may aggravate the risk of injuries.
- Those with cardiovascular issues like heart disease and high blood pressure should consult their doctor as performing isotonic exercise can raise blood pressure levels.
Isotonic exercise, a form of resistance training, is a great way to improve muscle strength and endurance. So, go for exercises like lunges, and deadlift to stay strong and fit.
Related FAQs
Is yoga isotonic or isometric?
Yoga mainly involves isometric movements. Isometric muscle contractions can be seen in asanas like uttanasana (standing forward bend) and dandasana (staff pose), where moving from the plank position leads to the lengthening of muscles and joint movement while resisting gravity.
Is jumping isotonic?
Yes, jumping is an isotonic exercise as it involves altering the muscle length with muscle resistance in motion. Jumping is also known as a plyometric strengthening exercise and helps increase isotonic movement involving muscle contractions. It especially improves the vertical jumping ability.

Unlikely habit helped new parents shed 50 kilos
Books are getting Australians into the gym and keeping them there longer, and the benefits of this emerging health trend aren’t just physical – they’re mental too.
Listening to audiobooks and podcasts helped Yvonne Kong, 41, and her husband get back into fitness after becoming parents and lose a combined 50 kilos.
Yvonne Kong, 41, used podcasts to get back into exercise and stay motivated. Yvonne Kong
It also helped them broaden their minds and carve out a bit of “me time” in our busy modern world.
Audiobooks and podcasts have given Aussies the chance to turn exercise into a vehicle for learning, training their minds and bodies simultaneously. Some are even taking their e-readers and paperbacks to the gym (more on that later).
“Listening to a story while working out actually helped me stay motivated and more consistent,” Kong told nine.com.au.
Like many Aussies, she used to dread hitting the treadmill and constantly found herself counting down the minutes until her session was over.
That changed when she hit play on a true-crime podcast during a workout.
Kong got so caught up in the story she forgot about the timer on her treadmill until her workout was over.
“I did an hour treadmill course and actually finished it without noticing,” she said.
Have you got a story? Contact reporter Maddison Skipper at mleach@nine.com.au
Since then, she’s found herself looking forward to exercising because it gives her an hour of dedicated listening time.
Her husband does the same while running; he took up listening to audiobooks because it motivated him to run longer and more often so he could get through the story.
The benefits of reading/listening while exercising
About one in three Aussies now listen to audiobooks when they exercise, according to data from Audible.
More than a third of them exercise for longer because of it, one quarter work out more often, and half experience better mood during exercise.
Data released exclusively to nine.com.au revealed both men and women reported these positive experiences at an almost identical rate, despite often having different workout routines and attitudes towards exercise.
Audiobooks are particularly popular with runners, more than a third of whom say they feel more focused on their run while listening.
Personal trainer Ben Lucas is one of them; he started listening while running to make time pass quickly and train his mind as well as his body.
“You’re out there anyway, so you may as well be learning something valuable while you do it,” he told nine.com.au.
What the experts think
Mindfulness expert Luke McLeod told nine.com.au there has even been some research into how exercise increases blood flow to the brain, which helps information retention.
Lucas devours business and personal development audiobooks like Atomic Habits by James Clear while working out, a trend which has become known as ‘personal development/PD stacking’.
The goal is to “double-up of some type of personal development like listening to an e-book, which works out the mind, while also working out the body,” McLeod said.
‘PD stacking’ is the new health optimisation trend, according to Luke McLeod. Luke McLeod
It’s all about optimising time in our busy world, which is particularly appealing to Aussies who are time-poor; like new parents trying to juggle work and a baby.
“When I’m with [my daughter], I’m trying to be present for her, so I’m not going to be listening to podcasts or anything,” Kong said.
“When I exercise, that’s my time.”

McLeod agreed that reading or listening while working out can be a great form of self-care for some Aussies.
The only pitfall is that not every workout is suited to it.
It’s hard to keep up with an audiobook or podcast if you’re trying to count reps while strength training, and there’s no way to read an e-book on a rowing machine.
“I find podcasts and audiobooks work best during longer, slower cardio sessions,” Lucas said.
“Whether it’s an easy run, walk, or long ride, you can relax into the session, tune out a little, and focus on what you’re listening to while still getting the work done.”
He also warned Aussies to stay aware of their surroundings and hazards like traffic, cyclists, other pedestrians, or uneven paths if they listen while exercising outdoors.
McLeod added that stacking habits like exercise and reading isn’t worth it if one interrupts the other.
Road testing reading at the gym
I’ve been in and out of the gym a lot over the last decade, jumping from strength training, to reformer Pilates, and other programs in between.
But my favourite way to exercise is to hop on a treadmill with my Kindle.
I rest it on the console, set a slight incline and a moderate speed and lose myself for an hour. No workout has ever felt faster or easier.
My Kindle fits perfectly into the little divot on the treadmill console meant for a phone or tablet. Maddison Skipper
The pros: Focusing on what I’m reading takes my mind off the clock and get through an hour of cardio without getting bored or losing motivation.
Reading at the gym also helps me stay consistent because it’s one of the few places I can just switch off and focus on my book without interruptions, so I want to keep coming back.
That hour of dedicated reading time has also been great for my mental health because it forces me to slow down and focus on something completely removed from any stress in my own life.
The cons: It did take a few sessions to get used to reading while moving, but raising the brightness on my Kindle and setting it to a larger font really helped.
Those who prefer to listen don’t have to worry about any of that though; just download an audiobook and you’re good to go.
I also invested in a pair of noise-cancelling headphones to muffle the dance music that plays over my gym’s loudspeakers, which made it much easier to focus.
Reading at the gym allows Aussies like me to work on my physical and mental fitness simultaneously. Maddison Skipper
Now the only downside to reading at the gym that I sometimes hit a slump after I finish a really good book because I don’t want to hit the gym again until I find something new to read.
The verdict: It’s not for everyone, but I have found that reading at the gym has been the best way for me to stay motivated and consistent.
I feel good about taking the time to work on both my body and my mind a few times a week, and I’ve been able to check some amazing books off my ‘to be read’ list while working out.
Audiobooks make it even easier for Aussies who want to exercise without the hassle of a physical book or e-reader, or who have different accessibility needs.

The Best Fitness Trackers for Your Lifestyle, Workouts, and Goals
Like every piece of gear you wear on your body day in and day out, fitness trackers are incredibly personal. The right tracker for you should be comfortable, accurate, and tailored to your lifestyle, including your preferred workouts and health goals. Do you bike, row, or strength train? Do you run on trails for hours at a time, or do you just want a reminder to stand up every hour? Do you want to wear it on your wrist or your finger, or tuck it into your sports bra?
No matter what your needs are, there’s never been a better time to find a powerful, sophisticated tool to help optimize your workouts or jump-start your routine. We test dozens of fitness trackers every year while running, climbing, hiking, or just doing workout videos on our iPads at night, to bring you these picks.
Our top choice for most people is the Garmin Vivoactive 6 ($300), which works well with Android and iOS, but we also vouch for the latest Oura Ring 5 ($399) and the budget-friendly Google Fitbit Air ($100). For more wearables, check out our guides to the Best Smartwatches, Best Smart Rings, and Best Sleep Trackers.

Best Fitness Tracker Overall
Garmin makes some of the most accurate fitness trackers on the market, and the Vivoactive 6 is the best midrange option for most people. It strikes a solid balance between smartwatch features and fitness tracking, with support for both iPhone and Android users.
Why WIRED recommends: The Vivoactive 6 is accurate, comfortable, and packed with useful wellness features without feeling overwhelming. It uses Garmin’s proprietary algorithms to power features like Morning Report and Body Battery, which provide daily insights into your sleep, recovery, and readiness. It also has built-in satellite connectivity and GPS, so you can track outdoor workouts without bringing your phone along. There’s also incident detection, which alerts emergency contacts if it detects a serious fall.
Garmin’s biggest advantage remains its free Connect platform, which enables health and fitness tracking without requiring a subscription. The company also continues to add new software features through regular updates without putting them behind a paywall.
The trade-offs: Garmin launched Connect+, a $70-per-year subscription with extras like live tracking and access to Garmin’s AI-powered Active Intelligence. Former editor Adrienne So doesn’t think most people need it, but it’s worth noting if you’re looking for a completely subscription-free experience. The Vivoactive 6 may also feel like overkill for casual users who only want basic activity and sleep tracking.
