Too Tired To Exercise? How To Boost Energy For The Gym


Want to get fit, but frequently find yourself with no energy to work out? When you’re feeling tired or run down, the last thing you feel like doing is using up precious energy to head to the gym. For the occasional days where you’re feeling off, taking a rest day can be a great way to aid recovery. But if you have more days feeling off than on, this can be a sign that you need to make some lifestyle changes that will help to boost your energy so you can work out.

Here, PureGym Birmingham based Personal Trainer and Behavioural Change Specialist Suzy Quinn shares tips on how to create energy so you can get to the gym.

You probably already know that exercise has mental benefits and physical benefits, but did you know that it can boost your energy both short- and long-term?

Short-term energy boost from exercising

Logically, you might think that exercising would drain your energy, but it actually has the opposite effect. In fact, post-workout fatigue is a sign that something is not quite right. There are two main reasons exercise boosts energy short term:

  • Endorphins
  • Increased blood flow

Exercising produces endorphins, which are known as nature’s mood boosters. They can reduce stress and discomfort, and improve mood and pleasure[1], all which can help boost your energy levels.

Exercise also increases blood flow[2], which circulates fresh oxygen and nutrients to the muscles and brain to be used for energy.

Long-term energy boost from exercising

Exercising regularly can massively benefit our energy levels in multiple ways. It can increase the number of mitochondria in the muscles[3] – these are the organelles responsible for producing almost all of the energy in our bodies, so more mitochondria means more energy. It also builds up our cardiovascular health and endurance[4] which means daily tasks are less likely to fatigue us, and it can help to improve sleep[5], so you feel less tired during the day.

How to find energy to exercise

In order to get the energy boosting effects of exercise, you need to have the energy to exercise in the first place. In this blog, PureGym Personal Trainer and Behavioural Specialist Suzy Quinn shares some practical tips on how to boost your energy for the gym.

  1. Make sure you are eating and drinking enough

    As the saying goes, food is fuel – without adequate nutrition, you’re not going to have the fuel needed to move your body.

    Make sure you have eaten enough high-quality food during the day before your workout. If you’re exercising within 2-3 hours of a big meal, that should be enough to keep you going. If you’re planning on working out outside of that time frame, aim to have a snack 30-60 minutes before. You can learn more about how food provides energy here.

    The best pre workout snack for energy is one that is carb rich, with a little bit of protein. Carbs are your body’s preferred energy source for exercise, while protein helps repair and synthesis muscle growth. A banana and Greek yoghurt, egg on toast, or a low-fat cereal with milk are all easy to eat options, but you can find your own combinations. 

    Eating before a workout will give an energy boost, but it’s important to make sure you’re eating enough nutritious food and drinking water throughout the day too. One of the first signs of dehydration is fatigue, so if you’re not drinking enough water, you may feel low on energy no matter what you eat. Having too big a calorie deficit can also cause low energy levels, so make sure you’re not eating too little. While it may feel counterproductive to up what you eat so you can work out, especially if you’re trying to lose weight, but it’s better to have the energy to exercise so you can get the health and energy boosting benefits, while burning calories!

  2. Sort your sleep schedule

    When it comes to good health and having enough energy, the importance of sleep can not be overstated. When we sleep, our bodies use less energy – so the more time spent awake, the more energy we need. Our bodies also use sleep to repair and recover from stress, exercise, and more – without enough sleep we don’t get the recovery needed.

    Plan a sleep time routine that allows enough sleep (around 6-8 hours) before you have to get up and stick to it. If you struggle getting enough good quality sleep, check out our tips for improving sleep here.

  3. Have a coffee

    If you prefer to work out in the morning, having some caffeine 45-60 minutes before your workout can act as a pre-exercise energy booster[6]. There are plenty of pre workouts and energy drinks catered for the gym, but a coffee works just as well. You can learn more about what pre-workout is here.

    If you go down this route, make sure that having caffeine isn’t the only way you’re upping your energy levels – getting enough food and sleep is still important!

    You should also avoid having caffeine in the afternoon as this can impact your sleep, and leave you feeling more tired the next day.

  4. Find a workout time that works for you

    No matter how hard they try, some people just aren’t destined to be morning gym goers, while others struggle to get energy to work out after work.

    Rather than working against your body, find the time of day you feel most energised and plan your workouts for then. For example, instead of asking how to get energy to workout after work, ask yourself if there’s a time you could work out earlier in the day – could you get your stuff ready the night before and fit in a short workout before work? Maybe you could do a HIIT session on your lunch.

    Most PureGyms are open 24/7 so you can be as flexible as you want!

  5. Train with a friend

    When you’re low on energy, it becomes nearly impossible to motivate yourself – so even if you make it to the gym, you might not have a good session. Training with a friend adds external motivation and can boost your mood, which can create the energy needed to help drive a good workout. 

    If there are days you know you might be low on energy, why not plan to train with your friend in advance?

  6. Book a fitness class

    Booking group exercise classes is a great way to make sure you train when you really aren’t feeling it. It’s much harder to bail on a workout when you have something physically booked in – there’s no pushing it back until it’s too late to go! Being in a group, surrounded by other people’s energy, with an instructor and music to motivate, can also be very energising.

  7. Turn on the tunes

    Listening to upbeat, high energy music can actually give an energy boost and help you achieve more at the gym. Choose songs that you energy and have good rhythm, and focus on how the music makes you feel – this tactic won’t work if you glaze over the music and think about how tired you are!

  8. Plan in shorter workouts

    A workout doesn’t have to be 60+ minutes to be effective - doing just 20 minutes can be enough to boost your mood (and get those exercise health benefits too). Why not factor in some shorter workouts you can turn to when you’re feeling tired? HIIT workouts are a great way to improve your cardiovascular fitness, burn calories, and get your blood pumping – you can find some of our favourite short HIIT workouts here. You could also opt for a low intensity bodyweight workout, or a yoga flow.

Hopefully these tips will help to give you the energy needed to get to the gym, so that you can get more energy from your workout. If you need inspiration, check out our free workout videos here or download the free PureGym app. Ready to get started? Find your closest PureGym here.
