Weight Gain After Exercise
It takes a lot of effort to get back into the exercise game after a long time off.
If your goal is weight loss, and you’re doing your best to eat right and exercise, feeling like you’re gaining weight can be really disheartening.
However, the appearance of weight gain after exercise is usually normal – and the good news is, it can be solved.
It’s not a matter of body type or luck, but generally the result of not enough cardiovascular exercise (the stuff that gets your blood pumping), plus a lack of core and muscle strengthening. It also can be due to an off-balance between your caloric intake, and what you burn off. So don’t worry – it’s not going downhill!
If you’ve been spending a lot of time on the sofa, or have taken a long rest from a considerably more active routine, then your muscle definition and volume will likely have changed, depending on how long you’ve been away.
Pumping up muscles is a bit like blowing up a balloon. When you perform many sets with high reps, your muscles will start to swell and feel full. This is known as the pump.
If you’ve fallen out of your usual gym routine, your muscles won’t be worked as much as before and will, therefore, shrink in volume. And if you haven’t been getting much cardio in during your time off, you’ll have likely gained in body fat, whilst losing muscle.
Why you may have weight gain after exercise
While at the gym, you’ll be actively working your muscles at the same time as dehydrating. This combination of your pumped-up muscles, dehydration and overworked muscles might make you feel well toned at the time, but a few hours after exercise you may appear like you’ve gained weight.
Essentially, when you get back to the gym and start working your muscles again, you’ll see that balloon like pump happening, but will likely have less muscle definition and more body fat.
Water retention can be another reason you look like you’ve gained weight post-workout. When we push our muscles, we cause micro-tears (in addition to inflammation), and repairing our muscles requires both water and protein.
Muscles hold more water than tissue, and require water to help flush out toxins post-exercise. And of course, whilst we exercise, we’re usually drinking a lot of water, as we should be. Don’t be alarmed by water retention – drinking more helps your body continue to flush it out and lessen water retention over time.1
So, your muscles have pumped up but your excess body fat has remained.
People commonly see this in the abs area, having done several sets of sit-ups and a bit of running, only to find when they sit down exhausted at the end of the day that their physique is the same.
The answer is patience. A toned physique doesn’t happen overnight, and there are a few things to bear in mind if you’re not seeing the progress that you want. So, let’s break this down into areas that you can address: diet, cardio- and toning exercise.
We’re starting out with diet. A common misconception is that you need to go on a fad or extreme diet in order to lose weight.
But your muscles need protein to recover and develop, and your body needs all of the other macro and micronutrients to function properly. Exercising hungry is like a car running on empty. Fuel your ambition, and make sure your body gets the nutrition it needs.
Our bodies require the three macros (carbs, protein, and fat) as well as micronutrients like vitamins and minerals. The most important thing to keep in mind for weight loss is being in a negative calorie balance – burning more calories than you’re taking in each day.
Carbs are our body’s primary energy source – required for a good workout. A rough guide is to aim to get around 45-50% of your daily calories from carbs (although this varies person-to-person). When you’re lifting, your muscles need both carbs and plenty of protein to recover and build – aim for 1g of protein per kg of body weight and the remainder of your calories should come from healthy fats.

If you’re conscious of weight gain, our diet isolate shake will help you stay on track, and absorb quickly into the body. In terms of putting on weight, this is the result of either consuming more or burning off fewer calories – or a combination of the two. Weight loss should be planned over a longer period of time to ensure its sustainable and a healthy rate of weight loss.

While building muscle helps you increase your metabolism and burn more calories over time, the quickest way to get into a negative calorie balance – and lose weight – is through cardio exercise. As long as you’re fitting in adequate cardiovascular training and toning exercises, you will begin to see the progress you’re looking for. Here are a few suggestions to try out three days in a row, with one day rest between the next:
15 minutes running – Stick to a pace that you can see through to the end. This can be a brisk walk, as long as you’re getting your heart rate up.
15 minutes cycling or cross trainer – This is easier on your joints than running, with no impact.

Ab Toning Exercises
Tone up with the following. While all toning is useful, keeping your core strong helps you conquer other exercises in the gym.
Leg raises – 3 x 15. Lie on your back and bring your knees up towards your chest
Planks – 3 x 40secs. With your back and legs straight, support yourself on your elbows for three 60-second sets. When you are ready to move on, rest on a yoga ball, increasing the inclination.

While it can be frustrating to look like you’ve gained weight after exercise, if you’re just starting out with a weight loss journey, or you’ve just come back to the gym after a considerable amount of time off, it isn’t something to be concerned about. Gaining body fat after your lifestyle becomes slightly less active is totally normal and nothing to be worried about.
If you’re eating well, watching your calorie intake and getting enough cardio and resistance training, you’ll start to see results over time. Toning and weight loss don’t happen overnight, but consistent habits will help you reach the results you’re hoping for.
