If you’re wondering why you experience weight gain after leg day, then you’ve come to the right place.
In this article, I cover reasons why you weigh more after leg day, reasons why you might actually lose weight after leg day, and more.
3 Reasons Why You Weigh More After Leg Day
Increased Calorie Consumption
To gain weight, you need to be in a calorie surplus.
At a simple level, this means that you consume more calories than you burn.
Well, many people eat more calories on leg day as it helps improve performance, recovery, motivation, and muscle growth.
So by eating more calories, you’ll be in a bigger calorie surplus which will do wonders for helping you gain weight.
More Water Weight
Many people eat a lot more carbs on leg day.
Your body stores carbs in the form of glycogen, which is converted to glucose as a source of energy when you’re working out.
Now, for every gram of glycogen your body stores, it needs to hold an equivalent 3g of water. (Source)
So by increasing your carb intake, not only do you increase your glycogen stores, but you also gain a lot of water weight.
Increased Muscle Mass
When you train your legs, your muscle fibres experience micro tears.
Your muscles respond to these micro tears by repairing them and adding more muscle fibre in a process known as hypertrophy.
In simple terms, you get bigger muscles.
(Which is the aim of the game, right?)
Now, since the leg muscles are the largest muscle group, when you train your legs, you add even more muscle fibre compared to when you train other body parts.
As a result, you gain more weight on leg day.
Reasons Why Leg Day May Make You Lose Weight
Increased Calorie Burning
Generally speaking, leg day burns the most calories.
One reason is that leg day typically includes compound exercises like squats and box jumps.
Since compound exercises work out multiple muscles at a time, they burn a ton of calories.
Another reason is that the leg muscles are the largest muscle group.
As a result, they require the most energy (calories) during exercise.
You May Be Sick On Leg Day
Whether it’s because of eating a big meal before training, taking a massive dose of pre workout, or drinking too much water mid workout, many people feel nauseous after leg day.
And in some cases, this can lead you to actually being sick.
Without getting into the nitty gritty, sick has weight, and therefore if you are sick, you’re bound to lose weight.
4 Tips To Gain Weight After Leg Day
Increase Your Carb Intake
As covered earlier, increasing your carb intake helps you gain weight for 2 reasons.
First, every gram of carbs has 4 calories, so by eating more carbs, you’ll be in a bigger calorie surplus.
Also, eating carbs results in glycogen storage which adds some water weight to your frame.
Do A Low Volume Workout
In order to create micro tears in your leg muscles so that they grow, you need to be working at a high intensity.
So every set you do should be a big challenge.
However, each set you do will burn more calories which could take you out of a calorie surplus.
So it makes sense to limit the amount of sets you do.
This way, you can still grow your leg muscles without burning too many calories.
Increase Your Protein Intake
Eating more protein helps you gain weight for a couple of reasons.
First, your muscles need protein to help repair the micro tears and grow.
So to maximize muscle growth, you need to be eating plenty of protein.
Also, each gram of protein has 4 calories, so by eating more protein, you’ll be in a bigger calorie surplus.
Drink Plenty Of Water
As mentioned earlier, each gram of glycogen requires 3 grams of water.
So by drinking plenty of water, you’ll allow your muscles to store glycogen without taking water from other vital bodily functions.
This way, you can gain water weight without risking dehydration.
