There are 7 common mistakes girls make that stop their thighs and legs from changing shape. Plus, some genes and hereditary factors affect fat levels more in some bodies than others.
Reason one : Your expectations are unrealistic
Girls who think going to the gym for just two weeks is enough to see full leg muscles are wrong. In reality, it takes 4 to 6 weeks to see thigh and glute muscles, if you train legs 3 times a week.
Reason two : Your diet isn’t right

A nutritionist says if you want to change your body shape, start by changing your diet. Your diet should include protein, healthy fats, fruits, and veggies. Protein is really important for building muscle and helps burn fat faster.
Reason three : You don’t do enough cardio

If you train your lower body 3 times a week and still see no results, try adding cardio like climbing, cycling, going up and down stairs, dancing 30 minutes, or any activity that raises your heart rate.
Reason four: Don't add the clockwork lounge leg exercise to your routine

The clockwork lounge leg exercise is simple, easy, no equipment needed. It helps coordinate thighs, legs, and butt. It also helps get rid of cellulite. But as women age, they lose more muscle, so all girls should do this exercise.
Reason five: Exercises that hit more muscles than others

Some focus only on certain thigh muscles, but to get shaped and tight thighs, you need to work all thigh and knee muscles like hamstrings.
Working all thigh muscles lowers knee injury risk, so you should also work on your inner thigh muscles like
cossack squat:
Stand with feet much wider than shoulder width, squat down toward the right, bending your right foot forward and keep your left leg straight and extended.
Do this exercise in two sets of 8 reps each, doing both feet for each set.
The sixth reason: You don't train with enough weight

To shape and define your muscles, you must always change the weights you train with. But if you're a beginner, you can train with your body weight, but after a while, you should increase the dumbbell weight. You need to add weight when you can do 12 reps easily.
The weight you carry should challenge you enough to break it, then add more weight.
The seventh reason: You don't do exercises suitable for your body
You can't change your body shape, but you can improve it. For example, you shouldn't run if you have thin legs and want to increase their size and shape. Instead, focus on muscle-building exercises. Also, you should always increase strength training because it helps your health and fitness.
