First, thank you SO MUCH for posting such amazing information! Second, I’m looking to start this 12 week beginner program and just wondering if the weight should be slightly increased between sets, or just week to week? I have previous lifting experience and we would up the weight in between each set, but haven’t lifted consistently in a few years so just curious what you recommend. Thank you!!
Fitness can be intimidating. Even small, mom-and-pop gyms are usually full of weird-looking machines, equipment you don't know how to use, and unapproachable sexy people lugging around milk cartons full of pink water. Most of us new to the world of weights will walk into a gym feeling immediately overwhelmed. There's so much going on it's difficult to even know where to begin!
You need to strength train your whole body. I know you might be thinking, OK, I'll just do lunges, because Wini said lunges are the best lower body exercise. However, when you work your whole body you increase your metabolism and you burn more body fat and it's key as you're getting stronger and defining muscles that you, at the same time, have your body fat drop so that you can see those muscles. So you need to do a strength training workout for your whole body. You can certainly focus on your lower body. In Lean, Long & Strong we have a lower body concentration where you work your lower body a little bit more, yet you still need to work your whole body.
Poor fat: so misunderstood and neglected. Dietary fats got a bad rap due to a major landmark study from the 80s that—very erroneously—concluded dietary fats promote incidences of heart attacks and other illnesses. As a result of this, the government promoted eating as little fat as possible and corporations rolled out their fat-free and reduced fat foods to save everyone from their exploding hearts.

From this we see that active women would benefit from consuming 2 grams/kg of bodyweight, which is about 1 gram/lb of bodyweight. For a 150 lb woman, this means that she needs 150 grams of protein per day. Ideally your protein should be spaced out throughout the day. If you eat five meals a day, this would be 30 grams of protein per meal (continuing with the example above).
I’ll admit I have not looked at any of the individual studies to see what kind of study designs you were dealing with. PEDro is designed for RCTs, and I’m guessing you didn’t have all RCTs, so I agree it wouldn’t be the best tool to use. The Cochrane Collaboration has a tool for non-randomized studies. It’s pretty in-depth but could be simplified. I would most be concerned about tracking potential bias in selection of participants into the intervention/control groups, differences beteeen groups at baseline, adjustment for any differences at baseline, measurements of intervention adherence, and handling of missing data.

Step By Step Strength Training with Petra Kolber is one hour and five minutes and was released on DVD on May 4th, 2010. The video can be broken down to the two twenty minute segments and the two ten minute segments and the five minute abs segment. For me the video is an intermediate level workout. Granted the workouts are great, but goes at a little to fast a pace and there is no step by step instruction. When I first saw the preview videos on Amazon and YouTube they looked easy, but when you put them into practice it is a whole different story. It is for this video and others as well that I am an advocate for labeling the workouts: beginner, intermediate, advanced or something like it. Step By Step Strength Training with Petra Kolber gets a B-.
This is important. Lifting weights on stiff or “cold” joints and muscles will make it harder to move, and you’ll increase the risk of injury. If you’re weight training, warm your body up either with some cardiovascular activity that utilizes the muscles you’re going to work, or do a short set with a lighter amount of weight than you’re planning to use for your workout.
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.
Most people dread the word "diet" because it dredges up images of celery stick buffets and long lists of no-no foods. While it's hard to shake this negative association, it's important to learn that "diet" isn't a bad word. Before the media beat its true definition to a bloody pulp, a diet was simply any and all foods consumed by a person. Your diet, or the food you eat, is a crucial aspect to supporting your fitness goals.
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."
There were 53 comparisons of lower body strength gains, encompassing 2,287 subjects.  In these studies, men got 28.47% stronger, on average, while women got 30.64% stronger.  The average difference was 2.17%, with a 95% confidence interval from -0.92-5.26%. This was nearly a significant difference (p=0.087), but probably isn’t practically relevant and would be considered a trivial effect (d=0.08; 95% CI: -0.03-0.19).
That’s unfortunate: On average, a woman over 25 years old who doesn’t do strength-training exercises loses about one-half pound of muscle each year, or roughly 5 pounds in a decade, research has found. That makes you feel weaker and look flabbier, and results in about a 3% decrease in resting metabolic rate (RMR). Over time, this slowing metabolism can lead to an increase in body fat.
“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.”
The express route to a two-piece starts here: Bikini Body: Absolution. The pair of 20-minute workouts take the burn-and-firm approach to cinching with a cardio-focused session of jumps, squats, lunges and planks, then a toning series of what a reviewer described as "new-to-me ab exercises that kick the typical crunch's booty." Get ready for the wood-chopping arabesque move, one tester jokingly warned. So sore but so sleek!
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.

Some muscle soreness is likely when you start strength training, but you shouldn’t be cripplingly holy-crap-I’m-stuck-on-the-toilet sore for several days afterward. It’s an unfortunate fact that women are often encouraged to seek out extreme soreness, like it’s a badge of honor or, worse, that it’s the only indicator of a successful workout. (This is merely one of many misconceptions of the mind-boggling bullshit of health and fitness.)

This program would be an excellent choice with those goals in mind. In terms of calories, I'd recommend maintenance for the first month, +200 the second, and + 200 the third. Lastly, you can skip some of the optional cardio if you wish or you can adjust your calorie intake to account for the calories burned if you'd like to obtain the cardiovascular benefits.
