Loved this weight training video! I am 70 years old and have been working with your videos and DVDs for about 5 years. Although I have always worked out, I really like the consistency of your workouts. I do everything from yoga to weight training to aerobic workouts 6 days a week. I had open heart surgery to remove a benign tumor from the ventricle of my heart a couple of years ago and know that your workouts before and after surgery helped me to a quick recovery. Many thanks!!
Strangely, however, I couldn’t find a meta-analysis comparing strength gains and muscle growth in men and women.  I say “strangely” because there are meta-analyses covering damn near every facet of strength training under the sun.  Typically, once there are around a dozen studies on a given topic, someone’s going to do a meta-analysis. However, there have been 70+ studies comparing strength gains and muscle growth in men and women over the past 44 years, and no meta-analyses.
Take this a couple of times during the rest periods of your workout to monitor your heart rate. If you don’t have a stopwatch handy, think of this as a perceived effort of 6 to 7, on that 1-10 effort scale described above.  You should be breathing heavily, find some difficulty in holding a conversation (speaking just a few words or a sentence at a time), and on the verge of becoming uncomfortable.  
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.
This entire site is awesome. I have very little fat on my body besides my boobs and butt, and I’ve been wondering whether I “need” cardio or not to help build muscle/tone since losing weight is not something I need or am interested in. It sounds like I do NOT, which is what I wanted to hear. I’m down with dancing around and walking around the block and doing cardio “naturally”, but treadmills and other machines bore me to death and always made me feel like a quitter. I’m so glad to know I can basically skip that crap and just focus on weight training. I’m going to send this article to every chick I know.
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.
High Intensity Interval Training or HIIT is training where you alternate between intervals of high-intensity and low-intensity exercise. An example would be sprinting all-out for 100 meters then walking for 100 meters then repeating. One cannot sprint at full intensity for a prolonged time because sprinting and any other form of high-intensity cardio utilizes the anaerobic energy systems, specifically the Phosphocreatine system, which power short-term activity. After going all out, one must rest and give the Phosphocreatine system time to “recharge”. Additionally after sprinting all-out a couple times you are going to start feeling fatigued. After 10 sprints you are pretty much worn out. While you might not be able to sprint at full speed anymore you can still walk and jog as the intensity is not as high as sprinting and other uses the aerobic energy systems.
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.
I have all these cutouts from magazines, newspapers, etc with all kinds of great exercises. But this book has it all & in color. It has three level of exercises; beginners, intermediate and advanced--plus extras for different problems at each level. I was loaned a copy from my physical therapist to learn some exercises specific to my problems. After one week, I knew I needed to puchase my own copy, so I did and am delighted with it. It has all the exercises I need to do, inclluding use of stability balls of various sizes, weights, therabands, and others. I am able to exercise in my home, on my schedule, when I need, which giives me flexability. Great book for any woman who needs to start or maintain a good safe exercise program.
Why: "The muscles of your upper arms are very small from a volume perspective. Due to the muscle loss that has occurred since your 30s (sarcopenia), these muscles are atrophied," says Perkins. "It's critical to keep your biceps muscles strong so that you are able to carry objects safely and easily. It'll also make your arms look great." (For more moves for sculpted arms, try this at-home workout.)
We didn’t start with the fear that they felt was holding them back, we broke the fear down, and found lots of little obstacles that had been deemed as “life” and “unchangeable” and “that’s just the way it is” by developing awareness to the little steps on the road to their obstacles to happiness and success they were able to tackle them in a different way.

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.

Though BeFit is another company that provides the majority of it’s content via paid downloads, subscription services and DVDs, it can still be a great resource for free, at-home workouts. It boasts a plethora of videos in the 10 to 20-minute range, done by top fitness trainers like Denise Austin, Jane Fonda and Scott Herman, to name a few. While this channel is perfect for those who want to raise their heart rate in a shorter amount of time, there are a handful of longer videos sprinkled throughout the lineup for those with more time available. Unlike a few in this list, this channel is definitely not aimed specifically at women and has many workouts that would be suitable for men looking for a challenge.
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.
How her body has reacted: I’ve noticed that I’m so much stronger, I have more energy and I’m less tired. My body fat is lower and I’m much leaner, and you can really see the muscles. Wearing dresses and skirts in the summer and feeling confident is when it all pays off. I love my routine and I love the results. I am constantly preaching to friends and clients about squatting and dead-lifting and how great it is. People always ask me if I’m a runner and I respond, “No I’m a squatter.” It takes dedication and, for me, working out is a way of life, not a temporary fix.
It’s for those reasons that I champion these diet and fitness strategies.  These are the same techniques that we’re building our foundation around in our flagship course, The Nerd Fitness Academy: we understand that all women are different, which is why we present multiple training options for multiple environments, and diet advice that allows for flexibility based on one’s situation.
