Let's get started...

Exercise is often praised as one of the best things you can do for your body and mind. It helps you stay physically healthy, improves your mood, boosts concentration, and even helps manage stress and anxiety. For teenagers, especially during the ups and downs of school and growing up, it can be a fantastic outlet. But what happens when something healthy goes too far? Can you actually exercise too much?

The short answer is yes. Just like anything else, too much exercise can have negative effects especially if it's being used for the wrong reasons or your body isn't getting enough time to rest. In this article, well explore how to recognise when exercise becomes too much, the real-life impact it can have on a young person, and practical strategies to build a healthy, balanced relationship with movement.

When does exercise become too much?

Exercise becomes too much when it starts to do more harm than good. That can mean physically through injury, fatigue, or lack of recovery or mentally, when working out feels like something you *have* to do instead of something you enjoy.

It's important to understand that more isn't always better. Our bodies need time to rest, repair, and recover in between sessions. When that doesn't happen, the benefits of exercise can turn into problems like stress on the heart, hormone disruption, or burnout.

Signs you might be over-exercising include:

• Constant tiredness, even after sleeping
• Muscle soreness that doesn't go away
• Injuries that keep coming back
• Feeling irritable, anxious, or low
• Struggling to focus at school
• Skipping rest days or feeling guilty for taking one
• Exercising even when you're sick or injured
• Obsessing over steps, calories, or how long you worked out

Teenagers are especially at risk because your body is still growing. Too much training especially with not enough fuel or rest can affect how your body develops.

Real-life story: Luke's wake-up call

Luke, 16, got into fitness during lockdown. At first, it was a way to stay active and keep his mind off school stress. But soon, it became an obsession. I started working out every day, he said. Then it became twice a day. I was watching fitness videos constantly, comparing myself to influencers, and I felt like I wasn't doing enough.

Luke began skipping meals to get leaner and ignored signs of exhaustion. His schoolwork slipped, he was always tired, and eventually he developed an overuse injury in his knee. That was the turning point, he said. I realised I wasn't exercising to feel good anymore. I was doing it because I felt like I had to.

After opening up to a teacher and seeing a counsellor, Luke worked on building a healthier relationship with exercise. Now I take rest days, eat properly, and focus more on how I feel than how I look, he said. Exercise is part of my life not my whole life.

Why do some people push themselves too far?

There are a few reasons why a young person might exercise too much:

• Pressure from social media Seeing fitspiration posts can make you feel like you need to work out constantly to be healthy or attractive.
• Body image struggles Trying to change your body can lead to overtraining, especially if paired with unhealthy eating habits.
• Perfectionism Wanting to do everything perfectly, including your fitness routine, can lead to burnout.
• Stress coping Exercise is a great stress reliever, but relying on it too much can be a sign that something else needs attention.

It's easy to think, More exercise = better results, but that's not true. Rest and recovery are essential parts of getting fitter, stronger, and healthier both physically and mentally.

How much is too much?

The right amount of exercise varies for everyone, but here's what's generally recommended for teenagers by the NHS:

• At least 60 minutes of moderate to vigorous physical activity each day
• This can include activities like walking, cycling, dancing, PE lessons, or sports
• It's also important to include strength-building activities a few times a week like climbing, push-ups, or resistance exercises

However, more than 23 hours of intense exercise every single day with no rest can start to become harmful. Especially if you're not eating enough to support that level of activity, or if you're not giving your body time to rest and recover.

How to build a healthy exercise routine

1. Mix it up
Doing the same type of exercise every day can cause strain on certain muscles and joints. Try to include a variety of activities like strength training, cardio, and flexibility work.

2. Listen to your body
Feeling sore, sluggish, or overly tired? That's your body telling you to slow down. Taking a rest day doesn't mean you're lazy it means you're smart.

3. Eat to fuel your movement
Exercise without proper nutrition can lead to energy dips, poor focus, and even long-term health issues. Make sure you're eating enough and that includes carbs, proteins, fats, and plenty of water.

4. Take rest days seriously
You should have at least 12 rest days each week. You can still be active (like going for a walk), but avoid high-intensity training on those days.

5. Focus on how you feel not how you look
Movement should be about feeling stronger, more energised, and happier not chasing a certain body type or step count.

6. Set boundaries with social media
Unfollow accounts that make you feel like you're not good enough or push no days off mindsets. Follow creators who promote balance, body positivity, and rest.

When to get help

If you're worried that your relationship with exercise is becoming unhealthy, or if you recognise signs of overtraining, it's important to talk to someone. That might be:

• A parent or carer
• A PE teacher or school mentor
• Your GP or a school nurse
• A counsellor or mental health support worker

Also, if exercise is linked to anxiety, disordered eating, or body image problems, it's a good idea to get support from a mental health professional. Services like CAMHS, YoungMinds, and The Mix can help you find the right support.

Final thoughts

Exercise can be brilliant for your body, your brain, and your mood. But just like anything, it needs to be balanced. Yes, you can exercise too much and when that happens, it stops being healthy and starts being harmful.

The key is to listen to your body, focus on how you feel, and remember that rest, food, and fun are just as important as movement. Exercise should never be about punishment or pressure it should be about feeling good in your own skin and living a life that's active, balanced, and positive.

Move because it makes you happy, not because you feel like you have to. And if something doesn't feel right, speak up because your health, at every level, matters.

How are you feeling?

It is really important that when we need help, we feel able to ask for it. This could be speaking to a parent, a close friend, a teacher or someone else you trust. Sometimes it can be really hard to share our feelings with other people but if we are feeling low or don't know where to turn, sharing with others is really important. Teachers will always take you seriously and listen to your problems in confidence if you approach them for help. Likewise, parents, siblings or friends will help you if you reach out to them.
