The side lunge is a simple yet highly effective lower-body exercise that helps build strength, improve mobility and support better balance. Unlike a traditional forward lunge, it challenges your body to move sideways, strengthening muscles that aren’t always worked during everyday exercise.
For women over 40, including lateral movements such as side lunges can be particularly beneficial. As we get older, maintaining strength, stability and joint mobility becomes increasingly important for everyday activities, whether that’s climbing the stairs, carrying shopping, gardening or simply feeling more confident moving through daily life.
One of the best things about the side lunge is its versatility. It can be performed using just your body weight or with dumbbells as your strength improves, making it suitable whether you’re exercising at home or in the gym.
What Muscles Does the Side Lunge Work?
The side lunge strengthens several major muscle groups throughout the lower body and core, including:
- Glutes
- Hamstrings
- Inner thighs (adductors)
- Quadriceps
- Core muscles
- Lower back
These muscles work together to support good posture, balance and controlled movement. Building strength across all of these areas can help improve both exercise performance and the way you move during everyday tasks.
Benefits of the Side Lunge Exercise
Regularly including side lunges in your routine may help you:
- Strengthen your legs and glutes
- Improve hip mobility and flexibility
- Develop better balance and coordination
- Increase core stability
- Support healthy movement patterns used in everyday life
- Add variety to lower-body workouts by training movement in different directions
For many busy professional women, functional strength is often more valuable than simply lifting heavier weights. Exercises such as the side lunge help build the kind of strength that makes everyday activities feel easier and more comfortable, while also supporting long-term mobility.
How to perform the Side Lunge Exercise

Starting Position
Stand tall with your feet approximately hip-width apart.
If you’re new to the exercise, begin using only your body weight. Once you’re comfortable with the movement, you can hold a dumbbell in each hand to increase the challenge.
Relax your shoulders, lift your chest gently and engage your abdominal muscles to help support your spine throughout the exercise.
Step-by-Step Instructions
- Take a large step out to your right.
- Bend your right knee and push your hips backwards, as though you’re sitting into a chair.
- Keep your left leg straight while both feet stay firmly planted on the floor.
- Maintain a neutral spine and keep your chest lifted throughout the movement.
- Make sure your right knee stays in line with your toes rather than collapsing inwards.
- Push through your right heel to return to the starting position.
- Repeat on the opposite side.
Aim for 2 to 3 sets of 16 to 20 repetitions on each leg, choosing a weight that allows you to maintain good form from beginning to end.
Remember, controlled movement is far more effective than rushing through the exercise. Taking your time will help you recruit the correct muscles while reducing unnecessary strain.
Common Side Lunge Mistakes
Even simple exercises can lose their effectiveness if your technique slips. Paying attention to your form will help you get the most from each repetition.
Letting the Knee Move Too Far Forward
Try to keep your knee aligned with your foot rather than allowing it to travel well beyond your toes. Sitting your hips back naturally helps achieve a safer position.
Rounding Your Back
Keep your spine long and your chest open throughout the movement. If you notice your shoulders rounding forwards, reduce your range of motion until you can maintain better posture.
Forgetting to Engage Your Core
Gently bracing your abdominal muscles provides extra stability and helps support your lower back during each repetition.
Choosing Weights That Are Too Heavy
There’s no advantage in increasing the weight before you’ve mastered the movement. Focus on building confidence with good technique first, then gradually add resistance as your strength improves.
Beginner Tips
If you’re just getting started, there’s no need to rush your progress.
A few simple adjustments can make the exercise feel much more comfortable:
- Start with body weight before introducing dumbbells.
- Take a smaller step if your hips feel tight or your balance is limited.
- Move slowly and concentrate on maintaining good control.
- Practise in front of a mirror if it helps you check your posture and knee alignment.
- Expect your muscles to work, but stop if you experience sharp pain or discomfort.
Remember that strength develops gradually. Being consistent with your exercise routine is far more important than trying to do too much too soon.
Is the Side Lunge Suitable for Women Over 40?
For many women, yes.
When performed with good technique and an appropriate level of resistance, the side lunge is an excellent way to maintain lower-body strength, stability and mobility as we age.
Strength training is an important part of healthy ageing, helping to support muscle mass, balance and everyday function. Exercises that encourage movement in different directions can also improve coordination, which plays an important role in reducing the risk of trips and falls as we get older.
As with any exercise, it’s important to work within your own abilities. If you’re returning after a long break, recovering from an injury or managing a medical condition, seek guidance from your GP or another qualified healthcare professional before starting a new exercise programme.
Build Strength That Supports Everyday Life
Exercise doesn’t have to be complicated to be effective.
The side lunge is a practical movement that strengthens the lower body while encouraging better balance, coordination and mobility. Over time, these benefits can make everyday activities feel easier and help you move with greater confidence.
Combined with regular walking, mobility exercises, balanced nutrition, quality sleep and adequate recovery, strength training can become an enjoyable and sustainable part of looking after your long-term health.
Small, consistent habits are often the ones that make the biggest difference.
Side Lunge FAQ
What muscles do side lunges work?
Side lunges primarily strengthen the glutes, hamstrings, quadriceps, inner thighs, core and lower back while also improving balance and hip mobility.
Are side lunges good for beginners?
Yes. Beginners can start with bodyweight only before gradually adding dumbbells as their strength and confidence improve.
How many side lunges should I do?
A good starting point is 2–3 sets of 10–20 repetitions per leg, depending on your experience and fitness level.
Should my knee go over my toes during a side lunge?
Aim to keep your knee aligned with your foot while sitting your hips back into the movement. Focus on maintaining good form rather than worrying about an exact knee position.
Can side lunges help improve balance?
Yes. Because the exercise involves moving sideways and controlling your body weight on one leg, it can help develop balance, coordination and stability.
Can I do side lunges at home?
Absolutely. Bodyweight side lunges require no equipment and are ideal for home workouts. Dumbbells can be added later to increase the challenge.
