Muscle Building For Skinny Women

We've been helping naturally thin people build muscle full-time for the past fifteen years, with over fifteen thousand members, including athletes (high school, college, professional, and Olympic), fitness models, celebrities trying to look better for TV appearances, and most of all, regular people ranging from teenagers to grandmothers.
If you're a skinny woman who wants to gain weight, build muscle, and become stronger, I think you'd love our newsletter. It kicks off with a 5-part series that covers:
- How to lift for muscle growth
- How to eat for lean weight gain
- How to thrive with skinny genetics
- How to get stronger, healthier, and better looking
After that, we'll send you 1–2 newsletters per month to keep you updated on the latest muscle-building research, methods, and workouts—all of it 100% focused on gaining muscle and strength as a naturally thin woman.

We Help Skinny & Skinny-Fat Women Gain Muscle
For the past ten years, we've specialized in helping naturally thin people gain weight, build muscle, and become stronger. We've had clients ranging from everyday women all the way up to our Canadian Olympic women's rugby team. If you're finding it hard to gain weight, build muscle, or become stronger, this is the site for you.
This isn't a general site where we help the average person become fitter. Those sites are great, but if you're anything like us, they also drive you kind of crazy. They tend to assume that we're overweight and eager to get thinner—that we have a natural propensity to overeat. But we don't. We're naturally thin. We find it hard to gain weight. We don't need weight loss advice mixed into our strength training advice.
Here at Bony to Bombshell, we write about how to eat more calories, not fewer. About how to train for muscle mass and strength. About how to overcome the struggles of being naturally thin. And we help our clients make "bulking" transformations like these:




You may know us as the founders of Bony to Beastly (for skinny men) or Outlift (for everyone). Bony to Bombshell is our site for naturally thin women. I'm Shane Duquette, and I gained 55 pounds in a little over two years. I was lucky. I had the help of my business partner, Marco Walker-Ng, BHSc, PTS, PN.
Marco is a naturally skinny strength coach who had already gained 63 pounds. He'd also coached clients ranging from everyday people all the way up to college, professional, and Olympic athletes.
Before I met Marco, I felt lost. Whenever I would try to exercise, I would lose weight. I found it so frustrating that after every failed attempt, I would spend years festering in inactivity before I could muster up the motivation to give it another go.
When Marco taught me how simple this could be, I was blown away. And I gained 55 pounds while keeping my abs. I then reproduced those results with my roommate, who gained 45 pounds.
I also married a naturally skinny nutritionist, Cassandra. Not only has she gained 20 pounds herself (as a new mother), but she also helped us improve our nutrition and workout program.
