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.
I just encountered this article while looking for references to support my argument with someone on a website that their fears of becoming huge were unfounded. She is one of those women who does tend to put on a little more muscle than many of us, and she linked to a page loaded with images of steroid-chunked women as a an example of what she was afraid of.
When best friends and trainers Karena Dawn and Katrina Scott created Tone It Up, no one could have predicted the success of the company’s long-distance coaching methods just a few years later. Unfortunately, a few key factors are not free, such as the highly-praised nutrition plan and yearly workout DVDs. However, it is still possible to be incredibly successful with the shorter—but still dense—workout videos and recipes posted on YouTube. The best home regimen combines YouTube and the trainers’ website, on which they post daily plans combining multiple videos from the channel to create a full workout. To take it a step further, connect with the TIU community on Instagram for daily check-ins and challenges—such as the yearly Bikini Challenge.
How her body has reacted: Besides losing 8 pounds (which I couldn’t do before for the life of me with just jogging) in just three weeks, I’ve noticed I am starting to look cut again. There is definition in my abs and arms, which I’ve not seen in a long time. I feel tight, and my skin feels better all over, has better texture. I’ve also increased my normal running speed on the treadmill from 4.2 to 5.5 miles per hour in just three weeks. I feel stronger all over, and can run up and down the stairs in my house just doing chores!
Caffeine inhibits phosphodiesterase (PDE), causing a build-up of cAMP levels and greater effect of NE on fatty acid lipolysis. PDE blunts lipolysis; therefore inhibiting PDE allows lipolysis to proceed at an accelerated rate. The end result is there are more fatty acids available for oxidation after consumption of caffeine. Caffeine increases the release of fat from body fat stores so it can be burned, leading to fat loss.

I’m a woman and I totally agree with what you’ve said. Guys at my gym look at me as an outsider, giving me what-the-hell-are-u-doing-in-the-mens-territory looks. I never leave the gym unless my shirt is SOAKED in sweat. I lost so far around 50 lbs (I weight around 170 lbs now). I do challenge myself.. A LOT and I AM noticing changes. The problem is, I feel like my trapezious muscles (is that what they’re called?) are getting bigger and I hate that. I do shoulder press and that seems to bulk up my trapezious muscles. I don’t know what I should do. Maybe women can only bulk up in that area? I’m thinking maybe I should stop the shoulder press workout? But I do want my arms to be toned and my deltoids to show.
Essential fatty acids (EFAs) are vital to the proper functioning on your body. Dietary fats got a bad rap due to the diet fads of the 80’s and 90’s, which promoted eating as little fat as possible, but in reality EFAs are needed by the body and are part of a healthy diet. Eating fats does not equate to getting fat. In fact, most EFAs help support the fat burning process and maintaining a lean body. Do not be scared to eat good fats. EFAs are not the enemy. Also, be sure to supplement with a QUALITY EFA product, such as Scivation Essential FA.
How her body has reacted: Since making the switch, my body composition has changed drastically. It is something I didn’t notice right away and I truly still don’t understand how drastically it has changed until I look at pictures and see how much leaner my body is and how much stronger I am. I have more energy outside of training, which leaves me in a good mental space to focus on eating healthfully to fuel my body properly.
Insulin is the “storage” hormone. When it is secreted fat burning is blunted. By controlling insulin secretion by choosing low GI carbs you can decrease fat gain/increase fat loss. Stable blood sugar levels also improve energy levels and ones mood. All of our diets as based around insulin control, leading to leaner muscle gains with little to no fat gain.
And remember to fuel your workout properly. Too many dieters make the fatal error of cutting back on crucial muscle-maintaining protein when they want to slash their overall calorie intake. The counterproductive result: They lose muscle along with any fat that might have melted away. Sports nutritionist Cassandra Forsythe, Ph.D., co-author of The New Rules of Lifting for Women, recommends that you eat one gram of protein for every pound of your body weight that does not come from fat. For instance, a 140-pound woman whose body fat is 25 percent would need 105 grams of high-quality protein. That's roughly four servings a day; the best sources are chicken or other lean meats, soy products, and eggs.
Hi Jay.Your site is a breath of fresh air.I’m 67 and have loved working out with weights for years.Started with library physique books as they were called when I was a boy.Common sense books that taught progressive weight training.Thank you for bringing back that common sense for today’s people.I will send this information about training to my daughter. She will appreciate your advice. Best regards
How: Hold a 5-10 pound dumbbell in your right hand, and place your left hand on a chair or sturdy object for balance. Shift your weight onto your left foot and lift your right foot off the floor. Stand with a long, tall spine and allow the dumbbell to hang at your side. Press into the ball of your left foot so that you move upwards onto your toes. Keep your left knee fully opened without locking it. Press upward as high as possible, then slowly lower back to the starting position. That's one repetition. Aim to complete 15 reps on this leg, then switch and perform the same on the other.
Certified personal trainer Jessica Smith is showcasing her 15 years of experience in the form of weekly, full-length videos in an organized fashion. From meditation and walking practices to HIIT and barre, the channel is cleanly divided into 13 playlists that are actually maintained (a rare occurrence in the internet fitness industry). These videos have options for those with physical limitations, whether it’s chair-bound status, joint fragility or prenatal/postnatal body changes. And her adorable dog that frequently makes an appearance is an added bonus (is it just us, or is he much easier to identify with?). For those just getting started on a weight loss journey, we recommend the HIIT for Beginners series and accompanying free four-week plan.
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.
Many women worry that weight training will somehow transform them into Hulk-ettes, so they spend hours doing cardio in order to maintain their "feminine" figure. The truth is, women just don't have the hormonal support to gain muscle mass like men. The hormone testosterone is responsible for large increases in muscle mass. Women's testosterone levels are a fraction of men's. That means you can bench press without concerning yourself about how much chest hair you might grow.
Get in position for a kettlebell swing, except this time, as you hike the weight back, take a small step to the right with your right leg. Shift your left leg as well. As soon as the left leg lands, forcefully drive your hips forward, initiating the kettlebell swing. Repeat the pattern, this time taking a step with your left leg. Alternate reps on both sides. Do 3 sets.
The Bare Essentials Produce Extraordinary Results – all too often most people complicate health and fitness. But it’s not that complicated and this articles explain why (and how!) the bare essentials will allow you to achieve (and maintain) extraordinary results. You’ve save yourself a lot of time and frustration too when you harness the power of the essentials.

Want to be strong, healthy, and happy, and feel 10 years younger? Then it's time to pick up the weights. "Strength training is no longer about being buff or skinny," says trainer Holly Perkins, founder of Women's Strength Nation. "It's as critical to your health as mammograms and annual doctor visits, and it can alleviate nearly all of the health and emotional frustrations that women face today. And it becomes even more critical once you hit 50."

Next, bend your arms and slowly lower yourself until your chest is just about to touch the floor. Hold the position for a second. After holding it, straighten your arms again to return to the starting position. This is one repetition. Continue for up to 12 repetitions. To make it harder, try placing a gym bag or textbook on your back to add additional weight.

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.

Unfortunately, for all of us late to the gym game (those that didn’t quite follow through on those New Year’s Resolutions but have big plans to crush them next year), that coveted summer body might not be a reality just yet. So what do you do? Do you get a gym membership and promise that you’ll go every morning right before overspending on a picture-worthy acai bowl?

If you've ever tried to ditch the saddlebags and ended up a bra size smaller instead, you know that where you lose is as important as how much. As great as it might be to see the numbers on the scale go down, when you're on a strict cardio-only program your victory is likely to be empty. A recent study at the University of Alabama at Birmingham compared dieters who lifted three times a week with those who did aerobic exercise for the same amount of time. Both groups ate the same number of calories, and both lost the same amount—26 pounds—but the lifters lost pure chub, while about 8 percent of the aerobicizers' drop came from valuable muscle. Researchers have also found that lifting weights is better than cardio at whittling intra-abdominal fat—the Buddha-belly kind that's associated with diseases from diabetes to cancer.
Start in plank position, shoulders directly over elbows, forearms and hands on the ground, core and glutes squeezed tight. Now lift your right arm off the ground and reach your hand forward. Pause for 1 second then return to the plank position. Repeat on the other side. Work to keep your hips as square as possible as you do this. Alternate reps on each side for 4 sets. Work for 40 seconds, then rest for 20 on each set during Week 3. During Week 4, work for 50 seconds, then rest for 10.
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.
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.
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.

"Start with two days for two to three weeks, then add a third day," says Davis*.*"Ideally, you should strength train three to five days per week, but work your way up—starting off at five days a week might shock your body." Here's a comprehensive three-day-per-week plan to get you started. Aim to complete 20-minute sessions, then gradually add on time in ten-minute increments until you're working for 45 to 60 minutes, suggests Davis.

There were 32 comparisons of strength gains in young people, encompassing 1,745 subjects.  In these studies, men got 30.87% stronger, on average, while women got 45.71% stronger. The average difference was 14.84%, with a 95% confidence interval from 10.26-19.42%.  This was a significant difference (p<0.0001) and would be considered a medium effect (d=0.56; 95% CI: 0.39-0.74).  On average, strength increased about 48% faster in young women.
Ha cruising around your website and thought I would read this one for fun. Thankfully you didn’t state anything I have already come to terms with in order to get results (btw love your beginner routine, yay!). It’s crazy the amount of weird looks you get from people when you tell them what you do at the gym, including my own husband. Poor guy cringes when he asks what I’ve done at the gym that day, so now I just let him beleive Ive been running on the treadmill or some zumba thing, and thats where my results are coming from lol. Little does he know my butt sits a little higher everyday because of squats <3 <3 Thanks!!!
It wasn’t worth splitting apart the young and older subjects to do formal subgroup analyses for hypertrophy outcomes (I like having at least 20 studies to pool), but just looking at simple averages, it seems that men and women gain muscle at a similar rate regardless of age.  In the studies on young participants (N=8), the men increased muscle size by 13.1%, while the women increased muscle size by 14.1%. Similarly, in the studies on older participants (N=17), the men increased muscle size by 11.9%, while the women increased muscle size by 11.8%. Both of these differences are clearly trivial.
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.
In medical school, she’d counsel patients on the importance of exercise and feel like a hypocrite, she says, since she did little but shuttle from home to the hospital, spending her rare free time catching up on sleep. “My body didn’t feel good, and my mind didn’t feel very good either,” she says. But once she started taking her own advice, as a resident at Loyola University Medical Center, Dena quickly became a hard-core strength-training fanatic. Within a month of learning how to lift weights, she noticed she had more energy without needing as much sleep, she felt far less stressed out, and she saw her body tone up fast.
Wow I stumbled upon this site YEsterday and have come back home from work today to read more. I train the wife 4 times per week to loose fat and the training I MAKE her do I always get the “but I don’t want to build muscle” and as many times I tell her you won’t she moans so I then try my hardest to punish her with clean and presses, she hates me for this but I am really glad I found this site so much good reading.
Getting comfortable with a steady running routine is definitely something to be proud of, but when you're on that cardio grind day-in and day-out, you might be ready to change things up and take on a new challenge. Time to throw some strength training into the mix. It can be a little intimidating at first if you don't know where the hell to start, but understanding the basics can help you feel confident in your refreshed fitness routine.
Stand with feet slightly wider than hips, turned slightly outwards. Pull shoulder blades down and back. Keep chest lifted and chin parallel to ground. Tighten core and abdominal muscles, then shift weight to heels. Push hips back as if you’re about to sit on a chair and lower yourself until thighs are parallel or almost parallel to ground. Feet should be firm on ground and knees aligned with second toe, without going past toes. Extend forearms forwards to stabilise yourself [shown]. Avoid tucking tailbone or arching lower back. Return to starting position by pushing through heels.
