Why: "The chest muscles (pectorals) for all women are particularly weak and underdeveloped," says Perkins. "By increasing the mass in this muscle group you are adding a substantial percentage of lean mass towards your overall health. Additionally, the chest muscles are responsible for supporting breast tissue. This move will bring a bit more lift to your chest."
I was fixated on this path, focusing mostly on HIIT workouts, until Instagram started showing me a different kind of inspiration: More and more girls I follow were getting into weightlifting. It is crazy how the strangers you decide to follow on social media have such an impact on your life. Suddenly, the “Strong is the new skinny” mantra that women were spreading started to really speak to me. Shifting the goal from having a thigh gap to being able to challenge your body in new ways just made so much more sense. I also began to realize that my strategy for eating “clean” was just actually putting my body and mind in a dangerous place. 

Because of all of the muscle groups engaged simultaneously, this one is a calorie torcher! We estimate that in the 33 minutes of this video, the vast majority of the population will expend 8-12 calories a minute. That’s roughly 264-396 total. Here’s the thing; you can easily step up the burn even more by grabbing weights that are heavy & challenging for you to lift. Just make sure that you don’t ever sacrifice form for a heavier weight.
There's a longer-term benefit to all that lifting, too: Muscle accounts for about a third of the average woman's weight, so it has a profound effect on her metabolism, says Kenneth Walsh, director of Boston University School of Medicine's Whitaker Cardiovascular Institute. Specifically, that effect is to burn extra calories, because muscle, unlike fat, is metabolically active. In English: Muscle chews up calories even when you're not in the gym. Replace 10 pounds of fat with 10 pounds of lean muscle and you'll burn an additional 25 to 50 calories a day without even trying.
I just stumbled onto the Muscle and Strength website, and I'm really pleased with all of the information. I am 54 years old and frustrated with the 10-15 lbs gained since my full hysterectomy 4 years ago. I have always been active, have lifted weights for over 30 years, and have been an aerobic instructor for in past years. I am well educated in weight loss and weight lifting but can't seem to get back into shape after my hysterectomy. My doctor says that I should focus on programs that emphasize muscle growth as more muscle will burn more calories. In your opinion, would this program be the best fit for me? Thanks for your help!

My husband has just sent me this article, after listening to me bitch for years about wanting to be more “toned” but never wanting to join him at the weight bench for fear of getting manly muscles. The smugness on his face right now is nauseating, but I can admit the error of my judgement. (Not to him, obviously, but to myself, at least.) Thanks for the no-bullshit approach, I needed to hear it.
I appreciate such a thorough synthesis on this topic. As a systematic reviewer, my main concern would be a lack of systematic assessment of risk of bias in the individual studies. I see you did a funnel plot to see any bias by study size, but there are so many other things involved in study quality (study design, selection of participants, statistical adjustment for potential con founders, etc). I would be interested to see how many of these studies were fair or better quality (there are several well accepted quality rating tools available for various study designs). I would also be interested to see a sensitivity analysis to see if the pooled results differ when high risk of bias studies are eliminated, for example. Thanks for an interesting read.
"I find I have so much more success when I work out at home. You don't have to worry about what you're wearing, what your hair looks like, or what anyone will think of you. It's also my only alone time during the day. I do high-intensity interval training workouts from FitnessBlender.com. For my strength-training workouts I use Body Pump from Les Mills on demand. And sometimes I just make up my own lifting workouts based on things I've read online and podcasts I listen to. After I started working out at home, I also switched to a Paleo diet. The changes have been slow, but I've lost more than 20 pounds and put on some serious muscles. I can actually feel the muscle in my arms now." —Ami Paulsen, Denver, CO
Start standing, holding light-to-medium-weight dumbbells at your shoulders, chest up, core braced. Step your right foot back, then bend at both knees, lowering your torso until your left thigh is parallel to the ground. Press back up to standing, then press the dumbbells straight overhead. Lower them back to your shoulders and do a lunge rep with your left leg. Alternate legs on every rep until time’s up. Do 3 sets.

If you're looking to get as toned as 49-year-old Jennifer Aniston, here's the workout you've been searching for. Yogalosophy was created by the celebrity's long-standing yoga instructor, Mandy Ingber, "This workout will change your body and your mind," Aniston says on the DVD cover, as it combines resistance training and traditional yoga to build muscle and burn fat.
If you got something out of this article, I’d really appreciate it if you’d share it with your friends, your gym buddies, and anyone else who you think might benefit.  Since women are so underrepresented in strength training research, I find that this is a topic with so much misinformation swirling around.  I hope this article can serve as a small beacon of sanity.
What she does now: I’m really new to the weightlifting, and I love/hate it. I hate it because it is so foreign to me, and I have all sorts of preconceived ideas about who should really be doing weightlifting. Since it’s new to me, and I’m already experiencing a significant shift in the body in terms of inches, I have cut back on my other workouts. I’m doing hot yoga to stretch out and continuing with the swimming.

However, I am not stupid and I know that most moms just do not have that extra time to make it to the gym everyday-this is why I created my very own and affordable 12 week home workout program that uses barely ANY equipment! Instead, the program uses your bodyweight and one pair of dumbbells. It is absolutely perfect for busy mommies who want to workout when baby is asleep, for when it is super cold or super hot ouside, or just want to workout in the comfort of their own home.

Calorie counting should not be a life-long endeavor. It just doesn't effectively work in the long term. Studies show that calorie counting is prone to inaccuracy by upward of 25 percent—even if you triple-check your calculations and sources! The discrepancy arises from measurement errors on food labels, serving sizes and measurements which are impossible to reproduce consistently, different food quality, and a whole lot of guesswork.
“I think the most important thing about any athletic pursuit for women ... is the general sense of competence you get from knowing that your body can do whatever you need it to,” says Karen Ko, a Toronto-based strength coach and personal trainer. “This is huge for women. We’re socialized to defer to men in areas of physical activity — they are the experts, they are inherently stronger than us. Strength training challenges this narrative and is extremely empowering.”
When you strength train, your muscles are broken down, and then rebuilt over the next 24-48 hours. While your body is rebuilding those muscles, it’s recruiting more calories and energy to make the process happen (generally referred to as the ‘afterburn’ effect).  What this means is that your metabolism operates at a faster level even while you’re sitting on the couch after a workout.
