Squats

The gluteals — your butt muscles — are the largest and strongest muscles in the body. Their function is hip extension, or driving the upper legs backward. I cannot overstate how important it is to make sure these muscles are getting their workout. Activities that engage this muscle group include walking, running, jumping, and climbing. Lunges, leg lifts, and squats are all great for exercising the glutes. Here's the lowdown on some of my favorite squats.

Traditional squat (good if you're a newbie): Stand with your feet hip-width apart, with your weight on your heels. Keep your abs tight and your shoulders squarely over your hips. Sit back and down as if you were going to sit on a bench. Keep your back straight. Then stand up, straightening your legs, and repeat.

Sumo squat (good if you're a little more advanced): Place your feet as wide apart as you can and point your toes outward. Lower your body until your thighs are parallel to the floor. Hold for a beat, then exhale and press back up to the starting position. Repeat. This squat modification places a greater emphasis on the inner and outer thigh muscles.

One-legged squat (good if you're a hard-core exerciser): Stand with your weight balanced on your right leg. Lift your left foot an inch or so off the ground. Keep your head up, and don't lean forward; abs stay tight, and the right heel stays on the ground. Don't let the knee extend over the toe. Slowly lower yourself as far as you can comfortably go. Exhale and stand up straight, still balancing on the right leg. Continue for a full set on the right leg, then switch to the left leg and repeat. This modification requires tremendous balance and allows you to strengthen each leg. 

Squat Right

Don't let good form slip when you're busting your squats. Be mindful of the following:

Keep your eyes focused forward.

Don't lean forward or let your heels come off the ground.

Don't let your knees travel forward over your toes or turn inward as you lower or rise.

Keep your belly button sucked in toward your spine as you stand back up, being careful not to arch your back.

Can You Drink and Lose Weight?

Whether it's cocktails on ladies' night out, a beer at the bar, or a glass of wine with dinner, most of us enjoy a drink (or two!) every now and again. But remember what I've been teaching you: In addition to being aware of the foods that are good for you, you need to know which ones are not so great. And let's face it — alcohol is in the latter camp.

Simply, alcohol can sabotage your weight-loss efforts. It releases estrogen into your bloodstream, promotes fat storage, and decreases muscle growth. As soon as you have a drink, your body eats up all the glycogen (stored glucose) in your liver, makes you hungry, and reduces your inhibitions, so you're more likely to grab that chicken wing or stuffed potato skin at happy hour. Plus, alcoholic drinks contain many more calories than most people think — a 20-ounce serving of beer can pack 250 calories, a 6-ounce glass of wine contains 120, and a 1.5-ounce shot of liquor contains about 100. And that's without any sugary mixers.

If you're serious about losing weight, it's best to put alcohol aside until you're in maintenance mode. If you are going to have a drink, choose wine, which may protect the heart and help lower inflammation, or a drink with clear alcohol and no sugary mixers, such as a vodka and club soda or a Patron on the rocks with lime. One drink a day probably maxes out the benefits, though, so keep a cork in your alcohol consumption.

Water Intake

How Much Water Should I Drink?

Q: How much water should I drink each day? I hear all kinds of answers, including 1 ounce of water for every pound of body weight, and six to eight 8-ounce glasses. Which is right?

A: Water is a vital part of any diet and exercise program — not to mention life in general — because it aids every aspect of bodily function. Water is a huge component of muscle and is important for energy production, so if you want to make the most of your workout, make sure you're well hydrated.

There is no real one-size-fits-all approach to water consumption. As a general rule of thumb, men should consume 128 ounces of water daily, and women should consume 88 ounces, but this doesn't mean you need to drink this amount of water every day. Other beverages, as well as the moisture content of foods, also count toward your water intake. The following factors affect how much water you should consume:

Exercise: If you exercise or engage in any activity that makes you sweat, you need to drink extra water to compensate for that fluid loss. Drink 12 ounces of water two hours before a workout, and another 12 ounces 30 minutes before you begin. While you are exercising, you should drink 4 to 8 ounces every 15 minutes. You should consume an additional 12 ounces within 30 minutes of the end of your workout. During intense exercise involving significant sweating — say, during a marathon — you may need a sports drink rather than plain water, to replace the sodium lost in sweat.

Environment: In hot or humid weather, you need to drink additional water to help lower your body temperature and to replace what you lose through sweating. You also need additional water in cold weather if you sweat while wearing insulated clothing. Heated indoor air can cause your skin to lose moisture, increasing your daily fluid requirement. Additionally, altitudes higher than 2,500 meters (8,200 feet) can affect how much water your body needs — higher altitudes may trigger increased urination and more rapid breathing, which use up more of your fluid reserves.

Beat the Heat

5 Tips for Beating the Heat


Summer is in full swing and the mercury is rising. When you're exercising or playing outdoors, it's important that you take care to keep yourself cool. My fitness plan is tough enough — you don't need to add heatstroke to the equation! Follow these tips to make sure you stay safe in hot or humid weather.

Time it right. The hottest part of the day usually falls between 10 a.m. and 3 p.m. Do your workout early in the morning or in the evening, when the sun isn't directly overhead and the temperature is a little cooler.

Dress for the weather. Your body cools itself in part by perspiring. You'll help the process if you wear lightweight, somewhat loose-fitting clothing that allows the sweat to evaporate from your skin. Choose lighter colors because they won't absorb as much heat from the sun, and consider a hat or a visor to keep the sun out of your eyes.

Wear sunscreen. The last thing you want is a sunburn — it'll keep your skin from cooling off and sap precious fluids. Choose a sunscreen free of oxybenzone, a chemical that has been linked to hormone disruption. Use Skin Deep, the Environmental Working Group's cosmetics database, to see if your sunscreen is safe, and apply it at least 30 minutes before you head outside.

Drink lots of water. Sweating can dehydrate you very quickly, so it's important to keep drinking water. Drink 4 to 8 ounces every 15 minutes while you work out. If you exercise for more than an hour, you may need a sports drink or a snack to replace the salt and other electrolytes you lose as you sweat.

Watch your heart rate. In reaction to heat, your body increases blood flow to your skin in an effort to cool you off. The result is less blood for your muscles and an elevated heart rate. If you're not used to working out in the heat, you might find that you'll reach your target heart rate with less intense exercise than usual. Take it slow at first, and gradually increase your intensity.

Know the Warning Signs


What can happen if you get too dehydrated or exert yourself in the heat too long? Here are some possibilities, from the least to the most severe:

Heat cramps — muscle pain or spasms

Heat exhaustion — a state of elevated body temperature that's a precursor to heatstroke

Heatstroke — a life-threatening condition in which your body temperature rises above 106°F

If you experience muscle cramping, dizziness, fast and shallow breathing, cold and clammy skin, or nausea or vomiting, get out of the heat immediately and get some water. Heat-related illnesses are no joke, so don't take any chances!

HGH

The Hormone You Always Want More Of


Growth hormone (sometimes referred to as HGH, for "human growth hormone") is something we all want more of. It builds muscle, burns fat, helps you resist heart disease, and protects your bones — among many other health benefits. By increasing your muscle mass, growth hormone raises your resting metabolic rate and gives you more power for your workouts. It also helps you tap into your fat stores for fuel and discourages your fat cells from absorbing or holding on to any fat floating around in your bloodstream.

In addition to these amazing feats, growth hormone helps your liver synthesize glucose, and it promotes gluconeogenesis, a really cool process that allows your body to create carbs out of protein. This helps you lose fat faster while providing your brain and other tissues with the energy they need.

As with so many other beneficial hormones, production of growth hormone declines with age, and many things we do speed the decline:

1. We deprive ourselves of good-quality sleep. Growth hormone is released in adults in an average of five pulses throughout the day, the largest of which happens during deep sleep. Shortchange yourself on sleep and you'll shortchange yourself on growth hormone.

2. We eat too many low-quality carbs. Refined carbs, such as those in white bread and white rice, keep our blood sugar and insulin levels high, which suppresses the release of growth hormone. Protein, on the other hand, can facilitate the release of higher levels of growth hormone.

3. We don't exercise enough. When you don't exercise and your muscles become insulin-resistant, you increase your level of circulating insulin, which further suppresses growth hormone. We need to get off our butts and capitalize on this incredibly healthy hormone! One surefire way we can turn our bodies into growth hormone factories is with intense exercise. During intense exercise, and especially during interval training, growth hormone encourages the body to use fat as its fuel instead of glucose. Not only does this help you burn fat while you exercise, but it stabilizes your blood glucose level so that you have the energy to keep exercising.

Enhance Growth Hormone Naturally

You may have heard about HGH injections, but whatever you do, don't get HGH shots just yet. Taking HGH is controversial and risky, and it may even cause insulin resistance. You should try to change the behaviors that reduce your production of growth hormone before you ever consider injections!

Natural Sweetener

Looking for a Natural Sweetener?


If you've been reading this newsletter, you may already know how I feel about synthetic sugar substitutes. To put it mildly, I really, really don't like them because they confuse your body and mess up your metabolism. If you find yourself reaching for one of those blue, pink, or yellow packets to sweeten your coffee or tea, I want you to stop and try a natural alternative rather than putting chemicals into your body.

Sugar, of course, is natural, but its calories add up. Sugar is also murder on your dental health — the more you consume, the higher your risk of cavities. That's why I want you to try crystalline xylitol or stevia as a sugar substitute. Both are produced from natural sources rather than being chemically engineered: Stevia is made from the stevia plant, and xylitol is a sugar alcohol derived from the fibers of many fruits and vegetables. Xylitol does have a few calories, but it has less of an effect on insulin levels than sugar does. I prefer the taste of xylitol to stevia, but they're both good choices.

A possible benefit of xylitol is that it may help prevent cavities. In a recent study, researchers at the University of Washington gave teething babies and toddlers xylitol syrup and found that it prevented tooth decay. It's theorized that xylitol inhibits the growth of bacteria that can cause cavities to form, and for this reason the sweetener is used in many toothpastes and gums. Like other sugar alcohols, xylitol may cause mild gastrointestinal trouble if you consume a lot of it, but I've never had this problem.

If you like your coffee or tea unsweetened, more power to you! But if you need that little kick of sweetness, don't put your hormonal health at risk with artificial crap. Also, if you chew gum or use breath mints, be sure to choose products that contain xylitol or stevia (which may be listed as rebiana) rather than nasty artificial sweeteners such as aspartame.

Outdoor Workouts

Burn Those Cardio Calories Outdoors!


Does doing the same cardio routine at the gym make you feel like a hamster on a wheel? If so, why not go outside and get a change of scenery? Exercising outdoors can be a hit-or-miss proposition depending on where you live and the season, but when the weather is decent, there should be nothing stopping you. Take advantage of summertime to enjoy the fresh air! Here are some great alfresco cardio options to get you out of the gym.

Hiking: This is an awesome workout that I happen to love. It allows you to spend time in nature and discover your surroundings. Also, because of irregular terrain, you'll work your core muscles more than you would on a treadmill.

Running: Getting off the treadmill and running outside might help you burn even more calories. Try performing intervals by running or jogging in quarter-mile bursts. You can also work different muscles in your legs by doing intervals in which you run backward.

Swimming: Cool off, tone muscles, and get your cardio in. If you're just beginning to exercise, the pool is a great place to get started. Water provides more resistance than air, so it can make your muscles expend more energy than they would on land. Use a kickboard if you have one: Hold on to the board and use your legs to power you across the pool. Run or walk across the pool, tread water, or hold on to the side of the pool and just do kick drills for as long as you can.

Biking: Why not ride your bike to work instead of driving? You can commute and burn calories (not to mention save gas money)! Biking is an excellent means of exploring and a good calorie burner. It can be a great option if you're dealing with an injury, because it's low impact, causing less strain. But remember, a road bike is a totally different animal from a stationary or recumbent bike, so take it nice and slow at first until you get used to being on the open road.

Don't forget your everyday sports either — basketball, soccer, and the like are fun activities that allow you to get together with friends, get a cardio workout in, and enjoy the great outdoors.

Not Sure Where to Go?

Yes, the machines at the gym make it easy to track your cardio workouts by telling you exactly how far you're "traveling." But it's also a snap to plan outdoor runs and bike rides of whatever distance you want. You can log on to Mapmyrun.com or Mapmyride.com beforehand to find a great route. To get an accurate reading of calories burned, use a heart rate monitor. This goes for outdoor and indoor workouts — the calorie-burn readouts on gym machines are almost never accurate, so you don't want to rely on them.
