If you’ve been told you have a “skinny fat” body or you’ve used the term to describe yourself, you might be wondering what you’re actually supposed to do next. The internet is full of conflicting advice. Some people tell you to lose weight, others say you should bulk up, while some recommend hours of cardio or strict diets. It’s no surprise that many teenagers end up feeling confused.
The good news is that improving your body composition doesn’t need to be complicated. In most cases, it isn’t about following an extreme programme or changing everything overnight. Our complete guide to skinny fat and improving body composition explains the wider topic, while this article provides a simple, realistic plan that helps you build healthier habits over time.
Remember that your body is still growing and developing. The aim isn’t to create the “perfect” physique, but to become stronger, healthier, and more confident through consistent habits that you can maintain for the long term.
Step 1: Understand What You’re Trying to Improve
Before changing your routine, it’s important to understand what the “skinny fat” look actually means.
For many teenagers, it describes having relatively low muscle mass alongside a higher body fat percentage than expected, despite having a healthy or relatively low body weight. That means the goal usually isn’t simply to lose weight. Instead, the aim is to improve your body composition by gradually building muscle while supporting healthy body fat levels.
Thinking about body composition rather than body weight immediately changes your approach. Instead of asking, “How can I weigh less?” you begin asking, “How can I become stronger and healthier?”
If you’re still unsure about the term, our guide explaining what “skinny fat” actually means provides a useful starting point.
Step 2: Make Strength Training Your Priority
One of the most effective ways to improve body composition is to begin challenging your muscles regularly.
This doesn’t mean spending hours in the gym or lifting the heaviest weights possible. Beginners often make excellent progress with simple bodyweight exercises, resistance bands, light dumbbells, or beginner gym routines.
The goal is to perform exercises that gradually become more challenging as you get stronger. Over time, your muscles adapt, helping improve strength, posture, and overall body composition.
Aim for two or three strength training sessions each week, allowing time for recovery between workouts. Consistency matters far more than trying to train every day.
Our article on how strength training improves body composition explains why resistance exercise is one of the biggest drivers of positive change.
Step 3: Stay Active Outside Your Workouts
Strength training is important, but it’s only part of the picture.
The way you move throughout the rest of the day also contributes to your overall health and body composition. Walking to school, cycling, playing sport, spending time outdoors, or simply taking regular breaks from sitting all help increase your daily activity levels.
You don’t need to be exercising constantly. Small amounts of movement throughout the day can improve fitness, support energy levels, and make it easier to build an active lifestyle that feels natural rather than forced.
The most effective fitness routine is usually one that fits comfortably around your everyday life.
Step 4: Eat to Support Your Body
Many teenagers respond to concerns about their appearance by eating much less. In reality, improving body composition usually requires the opposite mindset.
Your body needs enough energy to recover from exercise, support muscle growth, and continue developing during puberty. Rather than focusing on eating as little as possible, aim to build balanced meals that include protein, carbohydrates, healthy fats, fruit, and vegetables.
Protein is particularly helpful because it supports muscle repair after strength training, while carbohydrates provide the energy needed for exercise and everyday activities.
Instead of following restrictive diets, concentrate on building eating habits that you can realistically maintain. Healthy nutrition is about consistency, not perfection.
Step 5: Don’t Be Afraid of Cardio
Some people believe that if you’re trying to improve a “skinny fat” body, you should avoid cardio completely. That’s a misunderstanding.
Cardio remains an important part of a healthy lifestyle. Activities such as walking, running, swimming, cycling, football, basketball, or dancing all improve your heart health, endurance, and overall fitness. They can also boost your mood and provide a great way to stay active with friends.
The difference is that cardio shouldn’t be your only strategy if your goal is improving body composition. Strength training helps build muscle, while cardio supports your cardiovascular fitness. Together, they create a more balanced approach than either one alone.
If you’re unsure why strength training is so important alongside cardio, our article on why cardio alone won’t change a skinny fat body explains how the two types of exercise work together.
Step 6: Prioritise Sleep and Recovery
Many teenagers focus entirely on workouts while forgetting that recovery is where much of the progress actually happens.
Every time you complete a strength training session, your muscles need time to repair and adapt. Sleep plays a particularly important role because it’s during rest that your body carries out many of the processes involved in recovery and growth.
If you’re regularly sleeping too little, you may notice lower energy levels, poorer training performance, and slower progress. Recovery also includes allowing yourself rest days, managing stress where possible, and avoiding the temptation to train intensely every day.
Looking after your recovery isn’t taking a step backwards—it’s giving your body the opportunity to move forwards.
Step 7: Be Patient With Your Progress
One of the biggest challenges is managing expectations.
Social media often makes it seem as though dramatic body transformations happen in a matter of weeks. In reality, improving body composition is usually a gradual process that develops over months rather than days.
Some weeks you’ll notice visible improvements, while other weeks you may simply feel stronger or find that exercises become easier. These are all signs that your body is adapting, even if the changes aren’t immediately obvious in the mirror.
Comparing your progress with someone else’s can make healthy improvements feel slow, particularly if they’re further through puberty or have been training for much longer. Instead, compare yourself with where you were a few weeks or months ago.
If you’re wondering what a realistic timeline looks like, our guide on how long it takes to change body composition explains what most teenagers can expect.
Step 8: Measure Success in Different Ways
It’s easy to become fixated on the scales, but body weight doesn’t always reflect the progress you’re making.
As you build muscle and improve your fitness, your weight may stay fairly similar even though your body composition is changing. That’s why it’s helpful to look for other signs of progress.
You might notice that:
- You’re getting stronger during workouts.
- Your clothes fit differently.
- You have more energy throughout the day.
- Your posture has improved.
- You feel more confident in yourself.
- Physical activities feel easier than they used to.
These changes often appear before dramatic differences in body shape and are a much better reflection of long-term progress than a single number on the scales.
Build Habits You Can Keep
The best plan for improving a “skinny fat” body isn’t the quickest or most extreme one—it’s the one you can continue following months from now.
Building muscle, improving fitness, and supporting healthy body composition all come from consistent habits rather than perfect days. Missing one workout, enjoying a takeaway with friends, or having a less active week won’t undo your progress. What matters most is returning to the habits that support your goals.
By focusing on strength training, balanced nutrition, regular movement, quality sleep, and realistic expectations, you’re giving your body the best opportunity to develop naturally and become stronger over time.
Improving your body composition isn’t about chasing perfection. It’s about building a healthier relationship with exercise, food, and your body—one habit at a time.
