You’re exercising regularly, pushing yourself to your maximum, adding more weight each time for one more round of heavy squats, lunges and/or HIIT.
But, it seems like your legs are just getting bulkier and bigger instead of smaller.
You’re finding it difficult to fit into your skinny jeans and shorts.
What is going on? Why are you getting bigger, instead of slimming down?
First of all – I understand this frustration. A couple of years ago, I was in this exact same situation and struggled with adding too much muscle for my liking.
But, there is a way around it.
This is why I decided to give some advice on how to lift weights without getting bulky – especially in your legs.
Most personal trainers will tell you that women cannot really get bulky.
If you have already tried talking to someone about your fears of getting bulky, there’s a good chance that you were told you’re just imagining things, or have a wrong mindset.
Or, that you should stick with lifting heavy because you will get a lot bigger before you get smaller. Well, not really.
While working out with personal trainers, I was a bit conflicted, ’cause every trainer always pushed me to lift heavy (especially more heavy weighted squats and lunges), but I didn’t like what it was doing to my body.
It wasn’t just my legs that were getting bigger, either.
My upper back was really broad and my crop tops and gym singlets didn’t fit anymore.
Overall, I felt like a bigger, bulkier version of myself. I just didn’t look slim and lean like I used to.
And no matter how many times I tried explaining that to my trainer, I just ended up getting frustrated or feeling guilty, because I am not happy with my ”strength gains.”
I couldn’t understand why some of my friends got amazing results from lifting weights, while I almost ended up hating heavy weights because they made me too bulky.
But then I started learning about different body types.
There are 3 main body types – ectomorph (Kendall Jenner, Karlie Kloss), mesomorph (Jessica Alba, Gigi Hadid) and endomorph (Kim Kardashian, Jennifer Lopez).
And, actually, 2 out of 3 female body types can get too bulky.
You must understand your body type to know how to build muscle without getting bulky.
If you are not sure about your body type, I have created a special Body Type Quiz that is completely free.
It will help you determine your body type in just 2 minutes. This is your starting point.
Ectomorphs are naturally very slim (think Victoria’s Secret models) and find it difficult to gain weight (both muscle and fat).
This body type can lift very heavy weights without getting bulky and often get amazing results from heavier weight lifting.
However, a lot of models do not lift very heavy because of the fear of getting too muscular.
Everyone’s body is different, and some models may be a combined ectomorph/mesomorph body type, and do have the ability to get too muscular.
Having big legs is something that no model wants, so they are very careful about this.
If you are a true ectomorph, heavy weight lifting will make you toned, and it’s very unlikely that it will make you bulky.
If you are a combined ectomorph/mesomorph body type, you still have the ability to get bulky if you do the wrong type of exercise.
Mesomorph girls can be slim or overweight, but they have the ability to lose and gain weight (both muscle and fat) very easily.
I am a mesomorph.
Mesomorphs need to be careful not to do too much weight lifting and high-intensity interval training (HIIT) because this can make them too bulky for their liking.
Endomorphs have a curvier body type, with shorter arms and legs.
This body type has a much harder time trying to lose weight, and they find it very easy to gain muscle, especially in their legs.
I would suggest that endomorphs avoid any HIIT and heavy weight lifting because this will just make them bigger and focus instead on doing more cardio with lighter circuit training (that doesn’t focus on building up too much of the leg muscle).
I know a lot of personal trainers say that lifting heavy weights is the key to slimming down, but for endomorphs, this isn’t really true.
I know you might think that you should just avoid any type of weight and resistance training and only do cardio, right?
Well, I’ve done that before, too!
I only did cardio, and yes, I’ve drastically slimmed down. But, I still always had fat around my hips and belly that I found hard to get rid of.
I ended up being more skinny fat than lean.
It wasn’t until I started lifting weights and building some muscle again that the fat really disappeared and I finally had abs!
Any type of resistance training will build muscle – even if you’re lifting low weight and high rep, doing bodyweight or endurance-based workouts, Pilates, or even yoga – these will all build muscle.
But the thing is, you need muscle to give your body tone and definition.
There is a certain way of exercising, including lifting weights and building muscle without bulking up, which I will talk about, below.
Having muscle also helps with keeping your body fat levels down.
A lot of women (and men) who only do cardio and avoid lifting weights will end up looking “skinny fat.”
Skinny fat is a term used to describe people who appear slim or skinny (in their clothes), but actually have quite a high percentage of body fat.
I used to be skinny fat, and whenever I avoid resistance training, I go back to being skinny fat.
There are SO many other benefits of strength training such as improved sleep, reduced stress, and anxiety, improved mood, lowered risk of heart disease, diabetes, and osteoporosis, plus lots more.
It really does benefit you both on the inside and out!
As you can see, lifting weights does provide a lot of health benefits, and if you know how to do it according to your body type, it can have great results.
The key to being able to lift weights and build muscle without getting bulky is:
Most bodyweight exercises will help you get lean and toned.
But there are some that are known to cause bulkiness, especially in 2 out of 3 female body types (these are discussed, below).
By lighter weights, I mean 1-2 kgs dumbbells, a resistance band, ankle weights or just your own body weight.
Lifting lighter weights with higher repetition (15-20) will not bulk you up.
Below you have my FREE Train Like a Model video course. These are full-length videos that will help you get toned without becoming too muscular.
Also, on my blog, you can find a lot more workouts that are designed especially for women who want to be able to lift weight without bulking up.
Here’s one example, below. :)
Pilates is exactly what I have been talking about. It’s often done using your own body weight, ankle weights or lighter weights that you can lift without bulking up.
I’ve also been to a few reformer Pilates classes, and these are great for toning up and slimming down!
The reformer machine uses resistance bands and a moving platform – it’s fantastic for your core.
In these classes, you will sometimes also use very light dumbbells for your upper body.
Swimming is great for toning your arms and doubles as cardio!
When I used to do cardio only, I also did some swimming. My arms were really toned, and I didn’t do any weights or boxing.
Yes, professional swimmers have bigger arms and shoulders, but they train twice a day, 6 days per week, and that is why this happens.
Swimming 1-2 times per week won’t cause you to become bulky.
Boxing is amazing for toning your arms really quickly, but not making them bigger. It’s also great for your core, too! And I know that a lot of Victoria’s Secret models do boxing.
I always notice a significant difference after just a few weeks of boxing. But just be careful about what type of boxing class you attend.
I’ve been to a few classes that do more of a boxing circuit, which includes a lot of squats, wall sits, burpees, etc. So, try to attend a boxing class that mainly focuses on boxing.
I know a lot of personal trainers won’t like to hear this.
The following exercises are great for your body (and mind), but they do build a lot of muscle and can make you bulky.
Also, I am mostly recommending this for mesomorphs and endomorphs. Most ectomorphs can lift heavy weights without getting bulky. But for the other two body types, these exercises should be avoided
Any time you lift heavy weights to failure, you will most likely build muscle (granted your protein intake is also high to moderate).
If you want to lift weights without getting bulky, avoid “training to failure” strength workouts.
I can see all personal trainers cringing here.
Yes, these exercises are great for your body and use LOTS of different muscles. But for me – and most of my clients that want to get lean and toned – squats just made legs bigger and chin-ups made their back broader.
Theses build SO much muscle and really change the shape of the body, in a way that I do not like. These 2 exercises will most likely make you bulky.
Other exercises that will most likely contribute to bulkiness include overhead pressing, deadlifts, lunges and burpees.
If CrossFit is your go-to-workout, and you enjoy lifting heavy, by all means, go for it.
But be aware that this type of training includes LOTS of squats and squat variations, burpees, deadlifts, chin-ups, and overhead pressing exercises. And if you are a mesomorph or an endomorph body type, these workouts will defiinitely make our legs and upper body bigger.
These are all exercises that I suggest you avoid if you don’t want to increase your muscle size (and not to mention that I’ve yet to meet someone doing CrossFit that hasn’t had an injury or badly messed up their spine).
Any short bursts of energy using your legs will make them bulkier and bigger, because of the muscle fibers it recruits and the energy system your body uses.
By short bursts I mean around 30 seconds. A lot of people do their sprints by running as hard as they can for 30 seconds, resting for 30-60 seconds and then repeating.
Unfortunately, this type of sprinting will make you bulky.
I do some sprinting (but only when I am already very fit). I prefer to do my sprinting as more of a fast-paced run.
I run faster than normal (but not at my maximum) for 2 minutes, and then rest for 1 minute. By the end of the 2 minutes, you should be so winded that you need to stop.
This type of running will still get you fit really quickly, and won’t make your legs bulky.
Any type of hill sprinting will make you bulky, especially your quadriceps (the muscles at the front of your thighs).
Avoid doing these and always option for a flat surface when doing cardio.
Walking on an incline on the treadmill will use your quadriceps and may make your legs bigger.
Walking is amazing for slimming down your legs, but it’s best done on a flat surface.
I’m sure you’re getting the theme here – anything uphill will bulk up your legs. The same goes for the step machine.
These are exercises that I am always questioned about. Results from doing workouts, below, vary, depending on the person’s nutrition, body type, genetics and all other factors.
But, I will try to provide some general advice.
If you are an endomorph, I would avoid spinning/cycling because it will make your legs bigger and more muscular.
You probably already have shorter and muscular legs, so there’s no need to increase the muscle size.
Mesomorphs can do it, but just monitor the changes in your legs and see if it makes them bigger.
For me, I can do a spin class once per week without getting bulky. But a lot of mesomorphs can’t (especially if you are a combined mesomorph/endomorph).
I would keep spin classes to once per week – maximum.
This is a tough one, because it’s such a great workout. But if you overdo it on leg exercises (jump squats, jump lunges, burpees, box jumps, etc), you will get bigger legs.
You can still do HIIT, but it’s all about the exercise selection. I still enjoy doing HIIT workouts, but the exercises I do are different.
I have written a blog series of HIIT workouts that won’t make you bulky, so you can use this for some ideas.
This is another tough one, because it is great cardio, especially if you can’t go outside.
Skipping will help you lose weight overall, but won’t necessarily slim down your legs. Skipping will also probably make your calves bigger, as skipping really focuses on your calf muscles.
If you want to slim your calves, it is best to avoid skipping. I personally don’t do any skipping.
I know a lot of women use the cross trainer in place of the treadmill, especially if they have knee injuries.
The cross trainer is a good alternative if you can’t walk, but for slimming your legs, it is not as effective as walking.
The cross trainer will build muscle in your quads because of the pushing down motion, but it will not build as much muscle as cycling or weightlifting.
Also, it won’t help reduce thigh fat as effectively as walking.
I have done a barre class and was surprised at how leg-focused it was.
We did lots of squats, squat jumps, squat holds, etc. It wasn’t really what I was expecting.
I’m sure different teachers have their own different barre routines, but the class I went to would definitely make my legs bigger.
Many women have also told me that they have developed big legs since doing barre.
I don’t think this is the case for all barre classes, or all body types, but just be cautiou
A lot of models don’t do any running because running actually builds muscle. It doesn’t build the same amount of muscle as cycling or weight lifting, but it will still build muscle.
Endomorphs in particular need to be careful with running.
Running is an amazing exercise for slimming all over – especially your legs – but if you build muscle really easily (like an endomorph), I would run with caution.
When you are running, monitor the changes in your legs and see if it makes them bigger.
If it does, I would avoid running. But if not, keep doing it!
Resistance training alone will not make your legs thinner, it will just make them more toned.
If you want to get thinner thighs, you need to do cardio!
I have written a really detailed blog post on how to do the right type of cardio to get skinny legs, so have a read for more information.
Also, you’ll find it very useful to read my blog post on how to slim down muscular thighs.
My 3 Steps to Lean Legs Program will help you slim your legs and tone your body without getting bulky in the process. I know from my own experience how frustrating it is to train hard and end up with results that you didn’t want. I used to work with a PT who trained me in such a way that caused my body to become too bulky for my own liking.
That’s why I created this program – to help women who prefer a more lean and slim look to get toned without having to worry about getting unwanted muscles. :)
”I trained with a personal trainer 3 times a week and while traveling, I used to do Kayla Itsines’ SWEAT program.
However, my thighs continued to be a problem despite exercising like a machine (in fact, I started measuring them and the more SWEAT I was doing, the bigger they became).
With [Rachael’s] program, I started seeing the results almost immediately. I measured my thighs, butt and muffin top and I lost inches after first week!
Here’s my 6-month transformation <3 I never thought I’d be able to lean out my muscles!! I have never felt happier & more confident with my body! Eternally grateful to you and your program!
This is only my 5-week progress, I was too eager to share the results with you. After years of trying other programs and even when I entered fitness competitions, I have never seen my legs this lean! I can’t wait to see my progress at the end of the 8weeks and again at the end of 16weeks after Round 2! Thank you and your lovely team. I am beyond grateful!
My program includes cardio, a complete 8-week meal plan and the style of resistance training that I mentioned in this blog post.
Also, the resistance training part of my program now has FULL-LENGTH videos that you can follow from warm up to cool down.
