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.

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.

The NHS has reignited the hybrid working debate – but WFH isn’t the health risk, this is

The NHS has reignited the hybrid working debate – but WFH isn’t the health risk, this is

The latest NHS exercise guidance reinforces what we’ve been preaching for years: hitting that 150-minute weekly movement target isn’t necessarily a get-out-of-jail-free card. It states that prolonged sedentary time is independently harmful, even for those of us who diligently carve out time for the gym. Verbatim, it says ‘prolonged sitting is harmful, even in people who achieve the recommended levels of moderate to vigorous physical activity’.

Chief Medical Officer Professor Sir Chris Whitty has been especially vocal about how detrimental it could be, highlighting hybrid working as a potential health hazard. ‘Without wanting to exaggerate, I think it’s important people think through, for example, hybrid working means quite a lot of people could very easily do very little other than leave their homes, where previously people would be routinely going to work, and that often meant at least some physical [activity],’ he said at a briefing.

I understand his logic, but it’s pretty reductive. Working from home isn’t the villain here – working from one chair is.

When we label remote work as “bad for your health”, we risk throwing the baby out with the bath water. In reality, for many – certainly the whole of the Women’s Health office, but also my less-fitness-conscious sister and stepdad, plus my entire friendship group – working from home often means being more active. It means more time to fit in a lunchtime run, to get some steps in before work, or to run some errands on a quick break.

Whitty suggests commuting increases incidental movement

On the other hand, plenty of office workers are more sedentary than they are at home. They sit at a desk for nine hours straight before driving home, whether to be seen to work tirelessly in front of their manager, or simply because they’re pulled from pillar to post in an office setting. For those who do have an office commute, eliminating that often stressful period of the day allows for better sleep, and more time for the movement breaks we need to break up the dreaded sedentary time. Not to mention that many commutes are almost entirely sedentary on a train/tube/bus.

The potential problem, the advice suggests, is the lack of incidental movement – the walk to the train, the stroll to a meeting room, or heading out for lunch – that’s naturally baked into your day when you’re in the “official” office. Without a commute or a day in the office, the onus is on you to manufacture movement in.

Regular stretching counts as a movement break

Without sounding evangelical, I’ve made this a non-negotiable part of my day. On WFH days, I work out or walk every single morning before I log on, and walk again every evening, even if just a lap around the block. During the day, I have a personal rule: if I’m downstairs, I use the upstairs toilet (and vice versa). Sounds excessive, but it forces me to activate my muscles and add to my step count every few hours.

Beyond that, the options are endless if you’re intentional. Use a standing desk or put your laptop on a kitchen worktop during calls. Take every phone meeting on foot, pacing your hallway if necessary. Set a timer to stand up every 30 mins to stretch, grab a glass of water, or do a quick load of laundry.

We don’t need to return to the office to be healthy; we need to bring movement back into our homes. The goal: to stop being professional sitters.

A Strength Coach Says These Two Exercises Are All You Need to Build Stronger Shoulders

A Strength Coach Says These Two Exercises Are All You Need to Build Stronger Shoulders

If you ask anyone on the gym floor how to grow a bigger set of shoulders, you’ll probably find that no two answers are the same. In between front raises, upright rows, machine presses and cable raises, shoulder day can quickly become a long list of exercises.

However, fitness creator and coach Eric Evans, also known on social media as Average to Jacked, thinks most lifters are overcomplicating things. He says that if he had to start from scratch after over a decade of training, he’d strip his shoulder workouts back to just two simple moves.

‘If I had to start over today, I’d build my shoulders with just two movements: a lateral raise and also a rear delt fly,’ he explains.

According to Evans, the reason for this isn’t because those exact exercises are magic, but because they work the correct movement pattern for the muscle.

‘Your body doesn’t know the name of the exercise you’re doing,’ he argues. ‘It really only knows the fundamental movement pattern you’re asking it to perform and also the amount of tension you’re placing on the muscle.’

So, you don’t have to perform cable lateral raises if your gym only has dumbbells, or use a reverse pec deck if you’d rather do bent-over rear delt flyes. As long as you’re training the same movement pattern and progressing the move with intensity or volume, you’ll achieve a similar result.

According to the coach, lateral raises deserve a place in your programme because they primarily target the side delts, helping create broader-looking shoulders and a more pronounced ‘V-taper’. Rear delt flyes train the back of the shoulders to create a rounder, more 3D physique.

‘I’m not including anything for the front delts, and that’s intentional,’ he says. ‘Your front delts are already heavily involved every time you do pressing exercises for your chest.’

For most lifters already bench pressing, incline pressing or overhead pressing regularly, he argues the side and rear delts are more likely to be the limiting factor.

‘I don’t think the front delts are what’s holding their shoulders back. I think it’s the side and rear delts,’ he adds.

He recommends focusing on controlling every rep, and avoiding using momentum to swing the weight. He also suggests working in the 8-15 rep range, adding reps until you reach the top of the range before increasing the load and repeating the process – also known as progressive overload.

‘You definitely don’t need to hit your shoulders from 10 different angles,’ he says. ‘You just need to consistently train these two movement patterns, push them hard and then gradually get stronger over time.’

The Bottom Line

Research suggests muscle growth is driven more by sufficient training volume, progressive overload and proximity to failure than by constantly changing exercises and programme hopping. In fact, that could hinder it. So if your shoulder workouts have become jam-packed with unnecessary variations, simplifying your approach may be exactly what helps you make more consistent progress in the long term.


If there’s one thing Kori Sampson knows, it’s how to optimise your body composition for performance. To tap into his knowledge as an elite athlete and coach, we asked him to create a 4-week plan to help you move faster, recover quicker and keep pushing when the fatigue sets in – all while improving your muscle-to-fat ratio.

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core

Joan MacDonald didn’t enter a gym until she was 70. Really. Since then, the 80-year-old has transformed her health by losing three stone and building significant muscle, and now coaches other women through her training platform, Train With Joan, which she launched to help others boost their fitness at any age.

The premise of her app is simple: minimal-equipment workouts built around no-fuss, effective exercises that can be done anywhere. One ‘powerful core and stability exercise’ she swears by is alternating bodyweight clock taps. ‘This movement helps strengthen the muscles that keep you stable, balanced and moving well as you age,’ Joan explains.

Bodyweight clock taps benefits

Think they look too simple? That’s the point. Joan is adamant that ‘You don’t need complicated workouts to start getting stronger. Sometimes the most effective movements are the simple ones you do consistently.’

According to Joan, regularly performing bodyweight clock taps help:

  • ‘Strengthen your core which supports your spine and reduces strain on your lower back.
  • ‘Improve balance and coordination, helping you stay steady on your feet.
  • ‘Increase hip stability, which supports your knees and joints.
  • ‘Build functional strength for everyday movements like stepping, turning and reaching.
  • ‘Help reduce fall risk by improving control and body awareness’

  1. Stand on one leg with a slight bend in your supporting knee and brace your core.
  2. Keeping your hips level, reach your free foot forward to lightly tap the floor in front of you (12 o’clock), then return to the centre.
  3. Continue tapping to different “clock” positions—such as 3, 6 and 9 o’clock—maintaining your balance and control throughout.
  4. Complete all reps on one leg before switching sides.

Form tip: Move slowly and focus on staying stable. The goal is controlled movement, not how far you can reach.

How many reps and sets to do

Joan shares her advice, according to your fitness level.

  • Beginners: ‘3 taps per leg x 8-10 reps’
  • Intermediate: ‘3 taps per leg x 10-12 reps’
  • Advanced: ‘3 taps per leg x 12-15 reps’
