What's more, increasing that afterburn is as easy as upping the weight on your bar. In a study in the journal Medicine & Science in Sports & Exercise, women burned nearly twice as many calories in the two hours after their workout when they lifted 85 percent of their max load for eight reps than when they did more reps (15) at a lower weight (45 percent of their max).
How her body has reacted: The strength and confidence I’ve gained through powerlifting has changed my life and my perspective on fitness. There’s a stigma about women and powerlifting — the fear of gaining bulk. No, you will not bulk unless you have a strict meal plan that purposefully makes you bulk. You will gain definition and curves, which is what I believe many women who work out strive for. In addition, I’ve revisited running. I’ve noticed that I’m not tired as quickly. I also run faster and can run a longer distance without stopping. The fat I’ve lost and the muscle and strength I’ve gained through powerlifting have helped support my running milestones. If there was a zombie apocalypse, I think I’d be able to survive!

How to do it: "Every woman should do a full-body strength-training routine—such as this one—two days a week," says Perkins. "Then, on top of that, you may add the other components of fitness like yoga, dance, walking, or swimming." (Add one of these 3 new walking workouts that blast fat to your exercise routine.) You can complete all of these moves in one workout, or you can split them up if you're short on time. The key is consistency. Aim to complete 3 sets for each move, and choose a weight that makes it challenging to complete the final rep of each set.
You're right about one thing, though: training with weights will increase your lean muscle mass. That's a good thing! The more muscle you have, the more calories your body will burn. The more calories you burn, the leaner you'll get. Increased muscle mass will also add shape to your arms, take inches from your tummy, and even add some roundness to your booty! When women's magazines talk about "tone," they're really talking about strong muscles.

These cardio workouts are intended to be tough. If you can't complete your entire cardio session in the beginning, don't get discouraged. Push yourself a bit further each day until you can do the entire session at the pace listed. It may take a few weeks of building endurance to be able to complete the entire session.  You know you are working at the right level if you are not able to talk on the phone, or read a book, Dey says.
Hi! Thank you so much for this plan, it has helped me so so much. I used to just stick to cardio, but after a year of no weights, I realized that the volume in my body was depleting as my weight dropped. I even started to gain as time went on, so I decided to go to the gym and lift, but I had NO IDEA how to use wights or what to do. Then, I found this program!

I’d be doing you a disservice if I didn’t mention my own workouts that are available here at Make Your Body Work. Every single workout will challenge your entire body and will include elements of cardio, strength, and core conditioning. The uniqueness of these workouts are the “difficulty levels” that provide up to 4 distinct options for every single move. This makes each workout very accessible for newbies, yet challenging for super-fit users.


The hormone testosterone is responsible for the large increases in muscle mass seen when men lift weights. Women’s testosterone levels are a fraction of men’s testosterone levels. Normal testosterone levels in men are 200-1200 ng/dl while 15-70 ng/dl are normal in women. As you can see, men’s testosterone levels are SIGNIFICANTLY higher than women’s. Even if a man is at the LOW end of the men’s normal testosterone range (200 ng/dl), he still has more than twice the amount of testosterone as a woman at the HIGH end of the women’s normal testosterone range (70 ng/dl). If we look at the median or mid-range testosterone levels in men and women, men = 700 and women = 42.5. So on an average, men have 16.47 times more testosterone than women! It is clear that women do not have the hormonal support (testosterone) to gain muscle mass like men. Therefore, the fear of becoming big and bulky and looking like Arnold Schwarzenegger with a ponytail is unwarranted.

“There are so many misconceptions about strength and resistance training,” says Larry Tucker, a professor in exercise sciences at Brigham Young University. “One is that you’ll become muscle-bound”—so bulked up that your body becomes rigid. That myth was somewhat dispelled when athletes who started strength-training saw that they could hit a ball farther, jump higher and run faster, Tucker says. “Gradually we started realizing there are benefits beyond sports.”


Lose yourself in the high-energy rhythm of the Pound Rockout Results System, a five-disc sweatfest in which you wield drumsticks (aka Ripstix) instead of weights. "The drumming takes your mind off your muscles hurting!" one tester marveled. You'll "constantly tap the sticks" in each routine—core, upper body, lower body, intervals, tune-up and jam session—for a "totally unique" cardio blast.
Tired of sweating all over every piece of cardio equipment at the gym and still getting zero love from the scale? You need more iron. Not in your diet—in your hands. According to the National Center for Health Statistics, a mere 21 percent of women strength train two or more times a week. What you don't know: When you skip the weight room, you lose out on the ultimate flab melter. Those two sessions a week can reduce overall body fat by about 3 percentage points in just 10 weeks, even if you don't cut a single calorie. That translates to as much as three inches total off your waist and hips. Even better, all that new muscle pays off in a long-term boost to your metabolism, which helps keep your body lean and sculpted. Suddenly, dumbbells sound like a smart idea. Need more convincing? Read on for more solid reasons why you should build flex time into your day.

Start in pushup position, hands directly below your shoulders, feet slightly wider than hips-width apart. Now lift your right foot off the ground and place it just outside your right hand. Bend your right knee as you do this and try to keep your left leg straight. Feel the stretch along your hips, then return to plank position and repeat on the other side. Thats 1 rep.
Change up your workouts. Making even small changes to your strength workout can go a long way. Try altering the order of your exercises, or incorporate new pieces of equipment for the exercises you’re already doing, such as using free weights instead of a machine. You can also replace some or all of the exercises you’re doing with moves that work the same muscle groups. For example, instead of the chest press on a weight machine, switch to push-ups.

Tracking lifestyle markers improve can also be really motivating. They also give you valuable information about your progress.  For example, if you’ve been losing fat at a steady pace for six weeks, and suddenly, during the past two weeks, you’ve hit a plateau, take a look at your sleep and stress levels.  If your sleep has been poor for the last two weeks, there’s a good chance you’ve found the culprit.

How can one express that this is not the case any more clearly than explaining relative gains, different baselines and even addressing the implications of the results (the very fear of getting as big vs not getting any muscularity) at great lengths like Greg did? Hey, this is strongerbyscience, the home of strong-nerds, not the clientele for a …dumb-sized pink message sticker or fitness catchphrase in a glossy lifestyle magazine. I expect the audience of this blog of having above average interest in and knowledge about the topic and reading comprehension (only their written English becomes bumpy at times as a non-native speaker like me…). I fully trust the overwhelming majority to understand the article the right way and even educate others about it.
Thank you for this article – it confirms what I’ve read a few times, though sadly not often enough. I had this discussion with my sister that was at an all-girls gym – they ONLY have crappo machines, and you’re only allowed to use the free-weights if you’re working with a PT!! I shit you not… ANYWAY, I digress. I did have a question to ask – with regards to progression training, at what point do you decide to maintain, rather than constantly upping the intensity, or is that a really noob-y question??? =)
Paying attention to your form is definitely important when you’re doing bodyweight workouts, but the risk of injury goes up when you add more weight. Be sure you’re stretching regularly, and whenever  you have the opportunity, work with a trainer, physical therapist, chiropractor or structural integrationist who can help keep your bones and muscles working together and lined up.

Fast forward to now and I’m incredibly proud of where I’ve gotten in the past few years. I’m a personal trainer and group fitness instructor in NYC. I went from zero strength to being able to dead-lift over 200 pounds, doing several pullups in a row, and can clean and jerk almost my body weight. [Editor’s note: “Clean and jerk” refers to a weightlifting movement in which the barbell is pulled up to chest and shoulder height and then hoisted above the head.] I tell every woman I meet to stop being shy and get in that weight room! If you don’t know where to begin, hire someone. You will never realize what your body is truly capable of until you start picking up real weights.
Now bring yourself into a standing position by simultaneously straightening your back and legs. Remember to keep your back straight – do not let it slouch, as this can cause injury. Once assuming the straight stance, stick your chest out and contract your shoulder blades. This is one repetition. Do at least five repetitions to build strength and muscle. Once you can do these repetitions easily, add weight to the bag.
Why: "Due to gravitational pull, we are constantly fighting a battle to keep our body upright with good alignment," says Perkins. "This move strengthens all of the muscles in your back improving both bone density of the spine and proper integration of the spinal column. It also helps to fight off the decrease in bone that occurs over 50 and will keep your posture upright."
What she does now: Now I spend more time on weights than cardio. Your body actually works harder and longer during and after weightlifting than cardio, so you get a bigger bang for your buck. As a working mom, it’s hard to find time to get to the gym, but I make an effort to lift three to four times a week. I focus on different areas each day — legs, back and biceps, triceps and chest, and shoulders. I try to incorporate a short abs workout into every session, too. I never do the same workout routine twice. I want my body to be surprised, and challenge my muscles in a different way each week. I do a mix of machines, free weights and body weight exercises. In addition to lifting, I still do cardio about two to three times a week. I’ve been teaching Zumba for six years and I love it. I’m able to burn upward of 750 calories a class. I also walk a lot with my family.
Tbh, I think bias assessment is a bit different here vs. topics where the hypothesis is that there are differences between two things (you generally wouldn’t state a hypothesis in a meta-analysis, but there’s generally one there implicitly). The primary bias in research is publication bias – you slice and dice data to get significant findings, and significant findings are way more likely to get published than non-significant findings. So, if there’s high risk of bias and significant differences, you should probably assume the actual mean effect is smaller than the one you came up with.
How: Lie on the floor with your knees bent and feet flat on the floor. Hold a 10- to 15-pound dumbbell by one end so that the other end is on the floor when you extend your arms overhead. Begin with your core engaged, and draw your shoulders down away from your ears and toward your hips. From there, lift the dumbbell off the floor, keeping your arms long, and make a big arc over your body until the dumbbell is over your chest. Slowly lower the dumbbell back to the floor making the same arc. That's one repetition. Without fully releasing the dumbbell to the floor, immediately lift it again and complete 12 to 15 repetitions.

In a 2011 opinion poll reported by the Centers for Disease Control and Prevention (CDC), less than 20 percent of women contacted said they accomplished the CDC’s recommendations for 2 1/2 hours of aerobic exercise and two periods of strength training weekly. Yet the benefits speak for themselves. Inactive adults experience a 3 to 8 percent loss of muscle mass per decade. Resistance training may increase resting metabolism by about 7 percent and help minimize muscle loss.
I love the format of this video. It gives you easy options for choosing the exercise program you would like to do. Ms. Kolber is specific regarding form and breathing. You also have the ability to increase or decrease the impact of the exercises by changing your weights. I'm just starting an exercise program after years of laziness, and while a couple of the movements cause me a little difficulty, I soldier through and find I do better with each workout. Overall, I'd highly recommend this video.
Different exercises will require different weights, but there are some markers that can help guide you towards the right resistance, whether you're using dumbbells, kettlebells, or a barbell. Go for a weight that feel heavy enough to challenge you, but not so heavy that you sacrifice your form. For example, if you're doing 15 reps, you should feel pretty fatigued by the time you hit rep 15. If you can breeze through all your reps, though, that's a sign you should up the weight.

There were 28 comparisons of indirect measures of muscle growth (i.e. lean body mass), encompassing 1,607 subjects.  In these studies, men increased measures of lean mass by 2.03%, on average, while women increased measures of lean mass by 1.92%.  The average difference was -0.11%, with a 95% confidence interval from -0.40-0.19%. This was not a significant difference (p=0.47).
However, the role of testosterone may be overstated.  My friend James Kreiger recently published a super thorough analysis (note: paywall, but totally worth it) on all things testosterone and muscle growth, including analyses of cross-sectional research on people with different testosterone levels, studies comparing men and women, studies where people are given exogenous testosterone, and even studies where people were put on drugs to totally suppress testosterone production.  The main takeaway was that testosterone levels can dramatically affect the amount of muscle you start with, but they don’t really impact relative rates of muscle growth.

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.
Keeping your right arm fully straight and your core tight, lift your left hand from the ground and touch your right shoulder. Return to pushup position, then repeat the motion on the other side. Focus on keeping your hips square with the ground as you do each tap. Do 4 sets. Work for 40 seconds then rest for 20 seconds during each set for Week 1. During Week 2, work for 50 seconds, the rest for 10 seconds.
The good news is that this doesn’t have to happen! The word “sedentary” is key. Strength training is important for everyone, but after 50 it becomes more crucial than ever. It ceases to be about big biceps or flat abs but rather takes on a tone of maintaining a strong, healthy body less prone to injury and illness. The important benefits of strength training after 50 include:

If you are in reasonably good physical condition and need to lose a few pounds, you can check out our high-power fat-loss program. But if you’re starting from scratch with a lot of weight to lose and not much experience with exercise programs, then this program is for you. It’s based around walking and weights, and also includes one weekly session of what's called a "circuit program."

We learned that NE/E activate the receptors that stimulate lipolysis (fat breakdown). Research shows that NE/E secretion increases with exercise intensity. In addition, as cardio duration increases fat utilization increases while carbohydrate utilization decreases. So we need to perform high-intensity cardio for a long duration of time to maximize fat burning. The only problem is one cannot maintain high-intensity cardio for a long duration.

Most of the time, there are meta-analyses to answer questions like this.  A meta-analysis is essentially a “study of studies,” pooling the results from many different (smaller) research projects to make some sort of comparison.  Meta-analyses are useful because individual studies may have skewed results, and a single study can’t possibly hope to answer every facet of a general research question like “how do relative gains in strength and muscle mass differ between men and women?” (What if they used different exercises?  What if they used different training programs? What if they manipulated diet differently? What if they used people in a different age range? What if the study lasted twice as long? etc.)
