Workout Description

One of my coaches once told me that my genetic gift is my legs. I am lucky that I am blessed with long, naturally lean legs. However, they once attached themselves to the typical “white girl butt”…flat. They were also “skinny” once the body fat was stripped away. I used to buy into the belief that training heavy would make me bulky, so I did light weights or bodyweight exercises whenever I trained legs. When I decided that I wanted to transform my physique into that of a figure competitor, I was told repeatedly that I’d have to grow my legs and start lifting HEAVY.

I have since become a huge fan of heavy leg training and high volume to achieve lean muscle growth. I like a keep-it-simple approach, basic, compound exercises that work multiple muscle groups at a time. Effective. Efficient. In my opinion, the foundational exercises of a solid leg routine include: the squat, straight-leg deadlift and leg press. I build my leg training around those foundational exercises, focusing on strict form, high volume and heavy weight. I always cringe when I see women on the abductor and adductor machines doing light weight and high reps. I feel compelled to enlighten them and lead them to the squat rack, but I resist the temptation.

I’m also not a big fan of machines for any kind of training, but especially for legs. I think that barbells and dumbbells can provide an extremely effective, efficient and challenging leg workout. However, I still make use of the leg extension or leg curl machine from time to time.

Nutrition Tips

I like to eat higher carbs on the days I train legs. I will typically increase my starchy carbs by 50-75 grams and always follow the workout with a protein shake made with Whey Protein and 2 tablespoons of Gatorade powder. During contest prep, this usually changes with less carbs before the workout and I’ll substitute BCAAs in the post-workout shake for the Gatorade.

My female clients love this workout and always happily complain that they can’t sit down for a few days afterwards. The following leg workout is one that, if done right, you only want to perform once a week, giving your body ample recovery time before hammering the legs hard again the next week.

The Workout

Workout Notes

  • Squats - I typically do back squats (I do not use a Smith machine and don’t recommend it if you can use a squat rack or dumbbells) but there are several variations you can substitute to change things up.
  • Squat and Leg Curl Supersets - Rest 60 seconds between each squat and leg curl superset. For example, perform 10 reps of squats immediately followed by 10 reps on leg curls. Rest 60 seconds, then perform this superset again. By the time you finish your 20 sets of squats and leg curls your legs should be pretty fried. I like to finish off the workout with 10 last sets of lighter weight exercises to finish off the legs.

Keep the rest periods short and the weight as heavy as you can go without sacrificing form. I like to keep rest intervals at 60 seconds-2 minutes max!

Whatever you can do without sacrificing form. It should feel challenging, but not impossible. The number is going to be up to you because I have no idea how strong you are.

I work out at home and need a work out plan for building strength using dumbbells. Which work outs do you recommend on your website?

Are they adjustable dumbbells or fixed, Cat? You can do this one with heavy weights on the lower rep ranges. You can even go as low as five or six reps per set if you want to get stronger.

Hi Trainer Julie,
I'm 18 years old and weigh 92 lbs. Although people say I look healthy, I really want to gain some weight and build curves. Do you think this program would be appropriate for me, or am I too young? I ask because in a previous comment someone mentioned they were 15-18 and you told them to use light weights instead.

I'm 30 yr old healthy female, 135lbs, and about 21% +/- body fat......
I don't care so much about the weight as I want to drop my body fat % to about 14%, tone current muscle, and build more muscle.

I do not have a gym membership and right now can't afford it so all my workouts need to be done at home & I don't have any weights at home either. Like I said I'm totally new at this I don't know what exercises to do and what sort of diet I should be doing (high protien low carb or vise versa or...???).
Please help me????

Hey,you can achieve whatever you want with your body without a gym membership. If you want to manage weight ensure that you have low carb and high carb days to avoid hormone misfiring. I am not talking about the bad carbs,the good carbs.Utilise protein and protein shakes to especially if you want to build muscle and do not forget to drink water. Trust the process more importantly ❤️

I totaled my car a few years ago and injured my knees pretty badly. I have tried doing squats before but my knees always end up hurting after about 7 or 8 reps. Is it still okay for me to do this exercise or should I look for other ways to strengthen / grow my glutes?

Posted on: Fri, 09/20/2013 - 10:52

Hi, Although its called the Butt Builder is this a sufficient routine for lower body leg exercise performed once a week. Also I have been doing it for a month now. How will I up the game on it? My main aim is to improve muscle and tone and lower body fat.

How many times a week I have to do thise workout to grow my butt and legs

Posted on: Mon, 06/17/2013 - 17:15

Hi Julie,

I did the workout on Friday and loved it! It was super challenging and I used heavy weights for the squats. Sadly, I didn't feel much in my glutes and legs the day after and 48 hours post workout. I started with 35lbs dumbbells and finished the final 3 sets with 40 lbs. I am fairly fit and my form was spot-on, so I'm wondering why I didn't feel it. Increasing the weights could potentially throw off my form. Any suggestions?

Training to failure means performing repetitions until you aren't able to complete one more with proper form.

Hi, I started two months ago just working out.. I am trying to build slight mass, but mostly firm and tone up. How long till you see results like firmer/ less cellulite legs and glutes? Granted I am 42. Anyother helpful hints.

Posted on: Sat, 03/09/2013 - 08:07

I'm a total gym rat and I'm a huge fan of free weights and body weight. I work out twice a day: cardio in a.m. and lifting in the evening. I happen to love the Smith machine and won't join a gym without one. I'm a very serious lifter (not what I call a "PPW" (pretty pink weight) gal). The Smith machine allows me to 80+ pounds to do squats. This would be a VERY difficult weight for me to hoist over my shoulder / do my squats / and then hoist BACK over my shoulder and gently put the weight down.

Completely agree with you that transforming the body requires H-E-A-V-Y weights. I've done for my shape in 9 months of HEAVY lifting than I have done in 17 (seventeen) years of cardio. You are dead correct on that. I have more muscle than many of the women in my gym and I totally love the pumped up look. I don't care what a scale says and it has allowed me to work out freely - uninhibited - about keeping up with Mrs. Mass Media who says I should be a size 4 an 100 pounds.

I find it easier to just let my body do it's thing and lift heavy and "try" to eat right. Your exercises are all ones I do (heavy of course) and gals need to get off the light weights. I saw two girls (early college) giggling and lifting the 5 pound weights to do curls. I'm 45 and look better than they do. I'm not smaller than they are but I am stronger and my body shows I work out.

Great article.

Posted on: Tue, 02/05/2013 - 09:25

i have been jogging and lifting forever. not with any guidance, however. not a wimp at all, but i couldnt get through ten sets of squats. my legs are killing me today. i am going to run with this for a while.

Posted on: Sat, 02/02/2013 - 15:10

I guess, this may sound like a silly question, but I'm not a native English speaker and I am wondering what failure means? It says Leg Extensions, 3 sets, Failure reps? Does this mean descending or something? Thanks for the answer!

Posted on: Fri, 02/01/2013 - 17:55

On the row titled Leg Extensions, what does "Failure" mean? Also, on lifting (rather than cardio) days, I still like to get at least a mile of cardio in, do you recommend doing it before or after the workout?

I am not able to do the supersets 10 times. I am trying to build muscle. Is six sets fine and still get results? Also should I be doing thr lunges with weight?

Posted on: Wed, 01/09/2013 - 15:53

I love this workout! My butt got bigger by 1/2" in 3 weeks. Only problem is that I had to switch gyms, my new gym has the seated leg curl and not the one where you lay on your stomach. It feels different. Is it much different or is it in my head? The other thing that changed; I always used free weights for the squats, I was intimidated to use the barbell.. but I really want to try it. How much weight should I use and any tips on how to do it? (i used to hold 15 lb weights in each hand for the free weight, but I started at 12 lbs.)

Start with a weight where you can complete the recommended reps with great form. Perfect your form and slowly add weight so that you struggle to complete the reps. Once you're able to complete the prescribed reps, you should add weight the next time you squat. Again, your form is very important with squats. You may want to start with only the bar.

Hey, I really want to tone up my legs/bum, i already have really muscly legs naturally, they have always been big. I don't want them any bigger, although at the same time I would rather not lose muscle whilst trying to lose fat. Should I be doing workouts this intense on my legs, or should I do lighter workouts on my legs? :)

While losing weight, you'll still want to encourage your body to hang on to as much muscle as possible. You won't want to ease up on the legs!
