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.

During weeks 9-12, you will be lifting in the 4-6 rep range. What this means is that you want to complete at least 4 reps but no more than 6 reps for each set. If you cannot complete 4 reps, then the weight is too heavy and you should decrease the load. If you can complete more than 6 reps, then the weight is too light and you should increase the load.

Strength training by utilizing some form of resistance is a much better approach than focusing only on cardio if your goal is to achieve a toned, healthy physique, and there’s a lot of science to support it. Research shows that adding resistance training as part of your workout routine is a proven method for increasing Lean Body Mass and reducing body fat for women.
I just want to let you know that this article is absolute gold. You’re the real MVP for conducting a meta-analysis on this topic, especially when it’s so hard to find much research out there. More importantly, you’ve paved a way to explain more fully why strength training is so great for women to women and the benefits of it in comparison to men. Research is not only assuring and affirming, but it’s convincing for people who dabble with the idea of something, so thank you! Anyways, very well done and please keep doing what you’re doing!
This cardio could be done on the treadmill, elliptical, bike, running track, etc. We usually recommend the elliptical machine as it is low impact and easy to change speeds. We also recommend doing the Stubborn Fat Cardio Protocol separate from weight training, either first thing in the morning (if training in the evening) or on off days from the gym. To start, we recommend doing the Stubborn Fat Cardio Protocol 2-4 times per week.
"I found Cathe Friedrich on FitTV about seven years ago. I bought her Strong & Sweaty DVDs and fell in love with her workouts. Cathe inspires me because she is in her fifties, but is as fit as ever. Even though I'm a lot younger than her, I still find her workouts to be amazing—and probably the most challenging. Her newer workouts are my current favorites because they are short and intense, utilizing high-intensity interval training and heavy weights. I lost my baby weight (I have three kids), and I've put on 10 pounds of muscle. My kids love that I can do pullups at the playground with them." —Sierra Schwartz, Buffalo, MN

Your cardio will come in a couple different forms. On each day you train with weights, you'll do 20 minutes of high-intensity intervals. Choose an interval scheme that's challenging, but not impossible. Thirty seconds of all-out work, followed by 1 minute of recovery is usually a good place to start. One day per week, you'll do 30-45 minutes of low-intensity cardio. On these days, you can jump on your favorite cardio machine for some extra fat-burning.
While your body naturally produces vitamin D when you're under the sun, you're likely vitamin D deficient, especially if you have an office job or live in a region in which sunshine is a rare luxury. This deficiency affects overall health, and some studies suggest it may even hamper athletic performance and recovery from exercise. If you can't get enough vitamin D from the sun or from your diet, taking a supplement would be the next best thing.

I’m sure there are some people in a state of mild disbelief as this point.  After all, men have more testosterone, and testosterone is anabolic; therefore, men should be at a huge advantage when it comes to building muscle and gaining strength, right?  An implication of this analysis is that, assuming a given woman and a given man start with similar amounts of muscle mass and strength, they’d be likely to gain the same amount of muscle and strength if they both started lifting.  That just doesn’t sit right with some people.
Stand holding medium-weight dumbbells at your sides, feet hip-width apart, core braced, knees slightly bent. This is the start. Hinge at your hips and push your butt backward, lowering your torso. Hinge until you feel a slight stretch in your hamstrings; focus on keeping your core braced as you do this. From this position, squeeze your shoulder blades and row the dumbbells to your ribcage. Pause, then lower the dumbbells and stand up, squeezing your glutes. That’s 1 rep. Do 3 sets.

With that out of the way, this article is going to start with a review of the research comparing strength and muscle growth in men and women.  After that, I’ll focus just on the research using participants with prior training experience, and then I’ll review the inferences we can draw from sex differences in strength sports.  At the end, I’ll discuss some other sex differences and female-specific considerations beyond rates of strength gains and muscle growth.
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.
As we said before, women need to lift heavy, challenging weights in order to gain muscle. Lifting heavy weights will not cause women to get big and bulky like men because women produce a fraction of the testosterone that men do. When women begin working out, their goals are to tone up and gain shape/curves and following this program will accomplish just that! In this 12-week program, you will decrease the number of reps you complete and increase the load you lift as you progress. The number of sets per exercise stays the same, but the rep range changes.

I recommend exercises that simulate what you do in real life, exercises standing up using your body weight, for example. These exercises not only use the muscles you're targeting, for instance when doing a lunge you're working your legs, they also challenge your core muscles, which are the muscles of your abdominals and lower back. And they challenge your coordination, which you need in real life.
Men are, in the vast majority of cases, both stronger and more muscular than women.  They also gain both strength and muscle mass at a higher absolute rate.  That much is obvious.  However, relative rates of muscle growth and strength gains are, I think, the more interesting comparison since we largely tend to compare our progress to our own starting points.  If a man gets 10% stronger in response to training, can a woman also expect to get 10% stronger after training, or should she instead expect to gain strength at a faster or slower relative rate?
I enjoy these workouts. They're straightforward and good for beginners, not too complex or exhausting. My only complaint is that the 10 minute lower body workout is done without holding weights. After she says bigger muscles should use heavier weights, she doesn't show any weights with the legs, which are pretty big muscles. Bodyweight is fine, but this isn't advertised as a bodyweight workout. I think a beginner video should show basic squats and lunges with weights. Other than that, it's great.
I have always loved lifting, but I only started doing it regularly about 9 months ago. I needed to lose a bit of weight (fat), and I had no desire to sacrifice essential body parts to do so. After talking with some guy friends, I decided that lifting might be the answer. It was. I have lost two sizes, and 28 inches over all. I haven’t lost tons of weight, but I look like I have, and I did it without going on an excruciating and unsustainable diet.
Sandi! Congrats on your pregnancy — that’s so exciting!!! Honestly, my best tip for exercising while pregnant is to listen to your body! If you’ve been active stick to your normal routine (it will help you feel more normal too) and just listen to your body, pull back and modify when needed. I didn’t really start adjusting my workout routine till around 20 weeks and I slowly started modifying and now in the third trimester I’m doing lots of modifying. But pregnancy is so different for everyone so just listen to your body (it will tell you what it likes and doesn’t), stay hydrated and just try and keep moving! I stopped doing exercises on my stomach after 12 weeks, but I still do some stuff on my back if it feels ok. The main thing with bridges on your back is more when you’re at the end of second/beginning of third trimester and you want baby to be head down and doing bridges can confuse babies positioning. Again your body will tell you what it likes and doesn’t like! Hope that helps and happy #fitpregnancy! xo-Lindsey
