Another limitation is that, in studies on untrained subjects, we can’t necessarily assume that their backgrounds are identical prior to the start of a study. In other words, it’s possible that the “untrained” men in these studies had previously undertaken more activities outside the gym that required high levels of muscular exertion than the “untrained” women. If that were the case, you’d expect women to have faster initial relative strength gains simply from catching up with the male baseline.
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.
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.
Get in pushup position with a light dumbbell outside your left arm. Tighten your core and squeeze your glutes. Doing everything to keep your torso steady, grab the dumbbell with your left hand, lift it an inch off the ground, and move it so it’s now on the outside of your right arm. Return to plank position, then repeat the process with your right arm. Work for 40 seconds, then rest for 20 seconds each set in Week 9. In Week 10, work for 50 seconds, and rest for 10 seconds each set. Do 3 sets.
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.
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.
I started training when I was about 17 years old.I’ve always loved weight training! And despite all the warnings my friends, family and “MOM” gave me about bulking up & looking like a man, I never listened to them – not because I knew all the amazing effects of progressive overload back then. But lifting weights (and increasing them over a period of time) gave me a sense of euphoria. The 5 lb dumbbell that was so hard to lift in the beginning seemed like cotton – 2 months into it! I guess I’m trying to say is – I’m so glad I did not be “girly” and lift pink dumbbells! 🙂
"I tried many home workouts but I always end up going back to ShaunT. Insanity Max30 is my current favorite. At 30 minutes it feels like the perfect length and it's a very well-rounded workout. It's crazy intense and easily the hardest workout I've ever done! I did three, 60-day rounds of it last year and lost some weight. I'm down a clothing size and have been able to maintain my weight loss. I've also gained muscle. But perhaps my favorite benefit is that all the interval training has really boosted my cardiovascular fitness. My resting heart rate has dropped by 10 beats per minute!" —Katie Stumpf, Milledgeville, GA
Most of the time, there are meta-analyses to answer questions like this. A meta-analysis is essentially a “study of studies,” pooling the results from many different (smaller) research projects to make some sort of comparison. Meta-analyses are useful because individual studies may have skewed results, and a single study can’t possibly hope to answer every facet of a general research question like “how do relative gains in strength and muscle mass differ between men and women?” (What if they used different exercises? What if they used different training programs? What if they manipulated diet differently? What if they used people in a different age range? What if the study lasted twice as long? etc.)
What’s more, when you strength train, you get more calorie-torching bang for your buck. Working with weights keeps your body working long after you’ve stopped lifting. This is the process commonly called “after-burn.” There is much talk in exercise circles about the body’s ability to continue burning calories after exercise, called “excess post-exercise oxygen consumption,” or EPOC. A study reported by the University of New Mexico (UNM) reports that the body takes between 15 minutes and 48 hours to return to a resting state after exercise. This means you can continue burning calories after you exercise. The UNM study reports that the intensity of the workout has the most effect on how long the after-burn effect lasts.
We're going to mix it up this week! Instead of Straight Sets, you're going to complete your workout in a circuit style. This week, you'll complete 1 set of each exercise for 15 reps, then you'll immediately move on to the next movement with no rest in between. For example, on the Day 1 workout, you'll perform your first set of leg presses for 15 reps, then you'll immediately go to the goblet squat and perform 15 reps and then continue on to the next exercise with no rest in between movements. At the end of these four movements, you'll rest for one minute, then complete the circuit two more times.
