Most people should do both kinds of exercise for the biggest gains. But if you had to choose one, Clark advises, pick strength training. “Cardio is more digestible, it’s less intimidating, but people also get less and less out of it over time,” she says. As you grow fitter, you have to do more and more aerobic exercise to see the gains, she explains. Strength training, in her view, is the most efficient exercise for those with limited time.
Third, men and women may respond differently to low-load training.  At this point, there’s a tremendous amount of evidence showing that low-load training (i.e. sets of 20+ reps) can build muscle just as effectively as heavier training (though just because you can build muscle effectively with low-load training, that doesn’t mean you should).  However, only one of the studies comparing high-load and low-load training was done with women.  It found that women training with higher loads (6-10RM loads) gained way more muscle than women training with lower loads (20-30RM loads).  This stands in stark contrast to similar studies performed on men, suggesting that women may respond to normal, heavy-ish training the same way men do (mostly doing sets of 5-15 reps), but may not respond as well to low-load training.
Why: "This move is one of the number-one strengthening exercises that physical therapists use for back health," says Perkins. "It strengthens your ‘posterior chain' muscles that guide nearly every move you make, including your core, glutes, back, and shoulder muscles all at once, while helping to open the hips and shoulders." (Try these 12 hip-opening yoga poses for even more strength and flexibility.)
Put simply, "strength training means using resistance to create work for your muscles," says Hannah Davis, C.S.C.S. and author of Operation Bikini Body. So even if your mind jumps straight to those hardcore machines and massive weights, there are a lot of ways to create this resistance that require minimal equipment (or none at all). Bodyweight workouts can be an incredibly effective way to strength train. Squats and push-ups FTW. You can also use tools like dumbbells, medicine balls, TRX bands, resistance bands, kettlebells, and slider disks, to help get the job done, explains Davis. But if that sounds like gibberish don't worry about it. Keep it simple and focus on equipment-free routines first. No matter what you do, the most important thing is to find something that challenges you, says Davis.

One popular recommendation for weight loss is going "low carb." The range for what exactly constitutes low-carb varies among different individuals, but in general the target range runs between eating fewer than 50-150 grams of carbs per day. Fifty grams of carbs is equal to about one cup of raisin bran cereal or two slices of bread. It's not difficult to hit that target in one meal, or even a snack. To replace your carb-noshing habits, you'd have to include higher amounts of good fats and protein in your diet.

Strength training is a good idea for everybody. For the best results, try intermixing the strength training exercises with bodyweight exercises, and do them three times a week at most. More isn’t necessarily better when it comes to strength training – in fact, too much training can damage your strengthening process. If you also want to improve your cardiovascular health or lose weight, consider adding cardiovascular exercise, such as walking or running, which helps you burn fat.

In this case, most of the comparisons were nonsignificant, so if there are more unpublished null results floating around out there, they’d just reinforce the main finding here (and, in point of fact, there were; I also came across about a dozen studies stating that there were no significant differences between men and women in either strength or hypertrophy, but they didn’t report enough number or have figures to actually make a quantitative comparison). And for the significant differences, I don’t mind too much if they’re potentially overestimates because a) I’m very confident they’re true differences (I calculated how large of a true null would be needed to get below the significance threshold – it would take a study with anywhere from 3,000-11,000 subjects, depending on the comparison) and I’m not too hung up on the actual magnitude and b) I think the differences are probably only applicable for short-term training responses anyways (no differences in studies lasting 20+ weeks) so a misestimation of magnitude for short-term differences wouldn’t impact long-term implications to any real degree anyways.
Thank you for covering women for a change! As an older women I am always looking for information on both groups. I have found that I do better with higher reps simply because heavier weights end up causing me injuries. I think it may be because we start so much weaker (especially me!) that we are more likely to have imbalances if we miss a muscle. Does that make sense? I also get into situations often where I can do one weight many times but can’t really do a higher weight at all. (ie 10# 16 times but 12# not at all with decent form.) So I am now using weight gloves to achieve in between weights. I usually use weights I can lift 12-15 times to (or almost to) failure, doing 3 sets total but in rotation so I have some time to recover. Is that a reasonable approach?

2) I think how often you go to failure should primarily depend on a) how frequently you train a muscle/exercise and b) how much fatigue/soreness an exercise causes. If you’re just doing an exercise/training a muscle once per week, you can probably go to failure a bunch and be just fine. If you’re training the same muscle again 48 hours later, it probably wouldn’t be a good idea to go to failure very often. If you’re doing an exercise that causes a lot of soreness and fatigue (like DLs), you probably shouldn’t go to failure very often. If you’re doing an exercise (like biceps curls) that doesn’t cause much soreness/fatigue, you can probably go to failure more often.

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. 

How: Using 8- to 15-pound dumbbells, stand behind a chair. Place your feet under your hips and fold forward so that your head can rest comfortably on the chair or surface. Keep your knees slightly bent and your neck relaxed. Begin with your palms facing each other directly under your shoulders. Bend your elbows and pull the dumbbells towards you until your palms are next to your ribs. Draw the shoulder blades together at the top. Pause for two seconds, then slowly release back to the starting position. That's one repetition. Aim for 12 to 15 reps.
I am a 47 year old woman that has been athletic all my life. I love to tinker with my own training – my training goals are somewhat contradictory – faster 1/2 marathon times and stronger lifts. I just discovered your content a few months ago (MASS subscriber as well) and have found it extremely helpful in trying to create plans that achieve both without over training. But I really appreciate the attention and info for female athletes – this article in particular. There is much more work to be done by the research community – but anything that continues to educate women about the value of resistance training is a needed step to a healthier community
What she does now: I signed up with a personal trainer to help me learn more about weightlifting and strength training. Sometimes I think people don’t realize the value of having someone holding you accountable and helping you with form, education and motivation. I was determined enough to make the change that I went and purchased several months’ worth of sessions and committed to it. Little did I know that I would fall in love with how lifting made me feel.
Both BCAA and Glutamine oxidation/demand is increased during exercise. In order to meet this increased demand for BCAA and Glutamine, the body breaks down muscle protein. The goal of weight training is to increase protein synthesis. In order to gain muscle mass, protein turnover (protein turnover = protein synthesis – protein breakdown) must be positive. An increase in protein synthesis from weight training can lead to an increase in muscle mass. If we are increasing protein breakdown during training, we are decreasing the training session’s overall anabolic effect and limiting muscle growth.
And regarding when to switch from the beginner routine to the intermediate routine, the short answer is simply whenever the beginner routine stops working. Whether that’s after 4 months or a year… just ride it out for as long you’re progressing. I’ll actually be a writing a post in the next few weeks that will answer this question in more detail. Keep an eye out for it as well.
I just finished with the 12th week and I feel amazing. For the first time (IN MY LIFE) I feel muscle on my arms and can see my legs getting more defined. I lost around an inch on the narrowest part of my waist and lost 4 pounds! I'm not sure what I gained in muscle.... but either way, I'm pretty happy! It's not a "dramatic result" that lots of people notice, but it's enough to make me proud of myself!
This: But, there is still no difference whatsoever in terms of the approach. The same things still have to be done. The only difference is, when someone only looking to build a smaller amount of muscle reaches that goal, they stop right there and just maintain from that point on. The person looking to get “bigger and bulkier” would just keep on going.

If you’ll harken back to the beginning of this article, you’ll recall the two camps I mentioned:  1) people who claim that the process and outcomes of strength training for men and women are really dissimilar, and 2) people who claim that the process and outcomes of strength training for men and women are basically identical.  As I’m sure you’ve figured out by now, I think that the people in the second camp are closer to the truth than the people in the first camp. However, I think they miss the mark to some degree as well, since there are sex differences that extend beyond average results.

You see, we all build muscle the same way. We all require the same muscle building fundamentals to be in place in order for muscle growth to occur. We all need and benefit from similar amounts of weight training volume, frequency and intensity. We all need to force progressive overload to happen and lift heavy weights that are truly challenging for us. We all need to ensure certain dietary requirements are in place.
Don’t worry about what everyone else is wearing around you – this isn’t a fashion show. For shoes, look for a minimalist shoe with a hard, non-compressible sole.  Chuck Taylors are my personal favorite, but Steve wears Vibrams or Merrills. While there are some great shoe options specifically for weight lifting, as a beginner, the above multipurpose shoe will serve you just fine!
Why she switched: One day, I overheard another instructor say, “If you’re trying to lose weight, you need to incorporate weights into your workout routine, not just cardio.” That was the first time I’d really heard that. After a while of just cardio, I hit a plateau and didn’t really see any changes in my body, so I decided to start lifting. The biggest motivator for me was having a lifting buddy who was also just starting out, so we could keep each other accountable.
There’s nothing that says you have to pick one type of resistance training and stick with it. Versatility is the name of the game here, so you can rotate between ALL styles if you like – I personally do. It just depends on where I am, what’s handy, and what I’m working on. No matter which form of Resistance Training you choose, you’re going to love what what it does for you!
Slowly, bend the straight leg down into a squat, making sure the knee doesn’t go past your toes on the chair. The leg propped up on the chair or coffee table should also bend and lower. Continue squatting down until the knee portion of the leg on the chair or coffee table almost touches the floor. Hold it for a second. Return back to the starting position by straightening your front leg. This is one repetition. Do this for at least five repetitions.

My Free Yoga is pretty much exactly as it sounds – if offers free yoga classes for you to enjoy! It is a little different than other yoga options on this list in that it is really a hub for yoga instructors to post their free yoga class videos. The video library is huge and you can search for classes that focus on your specific problem areas. For example, there is a category for those suffering from hip issues and another for those experiencing back pain.

Start standing, then bend at the waist, working to keep your knees as straight as possible (it’s OK if they bend though), and place your hands on the ground ear your feet. Keeping your core tight, walk your hands forward until you’re in pushup position. Pause for 1 second once you’re in good pushup position, then walk your hands back toward your feet, again trying to keep your knees as straight as possible. That’s 1 rep.
Second, women may recover from training a bit faster than men (one, two, three).  When I’ve mentioned this in the past, the counterargument I typically hear is that women don’t create as much force, so of course their muscles won’t sustain as much damage, and will therefore recover faster.  However, that doesn’t make much sense when you think about it. For starters, I’m not aware of any evidence showing that people who are stronger or more muscular at baseline experience more muscle damage, more soreness, or larger/longer performance decrements than people who are weaker or less muscular, all else being equal.  More importantly, what each of your muscle fibers “feel” is the tension on that specific fiber; the contractile force of the entire muscle shouldn’t matter, as long as each fiber is being recruited to a similar degree and experiencing a similar amount of tension. I think the more likely explanation is that estrogen may exert a protective effect on muscle, limiting damage and potentially accelerating repair.
During weeks 1-4, you will be lifting in the 8-12 rep range. What this means is that you want to complete at least 8 reps but no more than 12 reps for each set. If you cannot complete 8 reps, then the weight is too heavy and you should decrease the load. If you can complete more than 12 reps, then the weight is too light and you should increase the load.
It’s no secret that Beyoncé is a crazy-good performer, and while we could never mimic her vocals, with some coaching, we thought we could pick up her dance moves. That’s why we were so excited to discover this video series featuring choreographer Frank Gatson, Jr., who breaks down every portion of Beyoncé’s Let’s Move! campaign, which features a remix of “Get Me Bodied.” Watch the first instructional portion and then the second one to learn the entire routine.

Some commonsense strategies are increasing your water intake, logging your food and something called "closer to the source." What I mean by that is when you're deciding what to eat and what to feed your family, ask yourself "Where did this come from?" We know where an apple came from, we know where an egg came from, but I'm not too sure where cheese doodles come from. You want to try to eat closer to the source. For instance, cheese is better than cheese doodles. There are lots of good commonsense strategies like that in Lean, Long & Strong .

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.
These simple weight exercises are an effective method of strength training for women that have proven results. How do we know? Just take a look at the toned body of TV and radio presenter Caroline Flack, who, in addition to practising yoga, is a fan of free weight exercises. When WH found out that the Love Island presenter enlisted the help of PT Sarah Lindsay of Roar Fitness, to devise free weight workouts for her to follow, we were keen to find out exactly what free weight exercises for women she recommends. And we did.
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.
