Hold two dumbbells with an overhand grip and let them hang at arm’s length in front of your thighs. Lift your left leg a few inches off the floor behind you; this is the starting position. Keeping your lower back naturally arched, hinge at your hips and lower your torso until it's almost parallel to the floor. Let your left leg stretch out behind you with your toes pointed down to the floor the entire time. The dumbbells should travel straight down toward the floor. Return to the starting position without letting the toes of your left foot touch the floor. That’s 1 rep. Do 2 sets per leg.

As such, we basically have no good research telling us about rates of muscle growth in trained men and women.  My hunch is that relative rates of muscle growth will continue to be similar, but we’ll have to wait on further research to say for sure.As you can see, only one of these studies (Alway et al.) reported a direct measure of hypertrophy, and only one (Garthe et al.) reported an indirect measure of hypertrophy.  Alway et al. is hampered by a very small sample, while Garthe et al. has a couple other confounding factors – 1) the main purpose of the study was to compare different rates of weight loss, so while the groups with differing rates of weight loss had similar numbers of men and women, it’s possible that group allocation affected results and 2) the study included athletes from many different sporting backgrounds, so while all of them did have prior training experience, it’s possible that the women were somewhat less trained than the men.
We learned that NE/E activate the receptors that stimulate lipolysis (fat breakdown). Research shows that NE/E secretion increases with exercise intensity. In addition, as cardio duration increases fat utilization increases while carbohydrate utilization decreases. So we need to perform high-intensity cardio for a long duration of time to maximize fat burning. The only problem is one cannot maintain high-intensity cardio for a long duration.
Cardio history: I wouldn’t consider myself an avid runner, but it was my top-choice workout before I discovered lifting. I would run on treadmills or trails around a lake or hillsides, do some kind of kettlebell workout, followed by whatever diet fad I was on at the moment. One thing was clear to me: I wasn’t getting any results. Sure, running made me sweat like a maniac and gasp for air every second. But I was also injured quite often. I would consistently hurt my hips, knees and ankles.
And while cardiovascular exercises such as walking, jogging or biking are important for heart and lung efficiency, it is strength training that provides the benefits that keep your body younger, stronger and more functional as each year passes by. If you want to be vibrant and independent for many more years, this strength-training workout will help you achieve just that.
I purchased Petra's Beginner Cardio video a number of years ago when I started exercising and go back to it when I need to "get back on the exercise wagon". Her style is very pleasant and the routines very manageable. So when I saw the strength training video, I was excited to try it. I love it. There are 2 10 minute, 2 20- minute and some extra routines, so you have flexibility around how long you want to work out. They are not overly challenging, but offer the attention to strength training that I like. I recommend for beginner/lower intermediate level workouts.
With 24 bodyweight workouts, there's no gym or equipment necessary to see results thanks to this workout DVD. You'll start your 90 days of guided training sessions with intense anaerobic exercise, followed by a period of rest, which repeats until the three months are over. There's three levels of difficulty though, so you're guaranteed to find a routine that works well for you.

Start lying on your back, arms and legs extended. Tighten your abs, pressing your lower back into the floor as you do so. This should lift your legs off the floor; work to keep them straight. Lift your shoulder blades off the floor as well; keep extending your arms back as you do this. Do 3 reps. During Week 7, try to maintain the hollow hold for 40 seconds, then rest for 20. During Week 8, aim for 50-second holds, then rest for 10 seconds between reps. Can’t hold that long? Hold for as long as you can, then come out of the hold and get right back into it until time’s up.
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.

How should I warm up for each exercise? Begin with a weight (or variation for bodyweight exercises) that allows you to perform 10 easy reps. Then add a little weight and perform 5-8 reps. You can perform a third set of 3-5 reps, with a heavier weight, if needed. Use the warm-up sets to find the proper weight/variation to use for the work sets. The goal of the warm-up sets is to hone proper technique and prepare you for the main workout.
Jillian Michaels, the star trainer on "The Biggest Loser" TV series, has a series of workout videos that feature her boot camp style of motivation. "No More Trouble Zones" is a DVD that highlights classic exercises such as squats, triceps kickbacks and lunges with bicep curls. Cathe Friedrich is known for her challenging workouts using an ultra-high step and heavy weights. Her "Butts and Guts," "Muscle Max" and "Core Max" workout videos will challenge even advanced exercisers. Kathy Smith's "Lift Weights to Lose Weight Double" offers seven 26-minute workouts targeting every muscle using a Swiss ball and dumbbells. Master instructor Karen Voight's "Firm Arms and Abs" and "Lean Legs and Buns" are two separate 40-minute videos that will define your entire body. "Maximum Body Shaping" includes 46 minutes of classic dumbbell toning exercises and intense plyometrics to accelerate muscle fatigue.
Place a kettlebell on the floor in front of you, and spread your feet slightly wider than shoulder-width apart. Push your hips back and slightly bend your knees, and grab the kettlebell handle with both hands. Start your swing with a “hike pass” to optimally load your hamstrings, insuring the handle of the bell is higher than your knees. Then explosively snap your hips forward, squeezing your glutes and lifting your chest; as you do this, the kettlebell will swing forward. As it falls back down, guide it back between your legs and, in one fluid motion, perform another swing. Do 3 sets.
If you’re new to weight training, don’t worry. Perkins created this four-week program to help you to build a solid foundation of strength training and shift your body into a new place after all that cardio. The really great news? You only have to do this routine twice a week. Each week, the moves will stay the same, but we'll make the routine harder by changing the program variables (like rest, sets, reps, or load).
