OK. Time to fess up. Have you ever stifled the urge to chuckle while at yoga class? You have to admit that, when you take a sweeping glance around the room, you and your classmates sometimes look less zen and more like twisted pretzels that have gone horribly awry.

Yoga is wonderful for strength and flexibility, not to mention what an awesome stress reliever it is. But it does open itself up to a fair share of jokes. If you're looking for a quick laugh, take a look at Fun Tuna's post Drunk People Yoga Positions. Don't worry, yoga, we only poke fun because we love you. And, hey, maybe a few extra drinks is the answer to finally being able to hold Plow Pose.

If you're looking for more information about yoga -- sober yoga, that is -- check out yoga on AOL Health.

You've just finished a tough workout. You're hot and sweaty so you reach for ... celery? It's long been known that water-rich fruits and vegetables can contribute to your hydration needs. But recent research shows that beyond contributing to hydration, some fruits and vegetables may hydrate your body twice as effectively as a glass of water.

Water is cool, refreshing and calorie-free, but certain types of produce have a leg up on H2O. Why? Because they provide nutrients like mineral salts, amino acids and vitamins as well as hydration.

When exercising, your body can lose electrolytes through sweat. Replenishing lost electrolytes is the whole premise behind sports drinks. But certain fresh fruits and veggies can replenish your body, too -- without all the artificial colors and flavors.

A steaming bowl of oatmeal is a great start to your day. Oatmeal is a whole grain so it fills you up, and it's a great source of slow-burning energy that will keep you fueled throughout your morning. What's more, the soluble fiber found in oatmeal helps to reduce low-density lipoproteins (the "bad" cholesterol). And who doesn't like a heart-healthy start to the day?

But despite all the health benefits and the low cost (old-fashioned oats cost approximately $0.13 per serving), is oatmeal a calorie-friendly choice for breakfast?

Have the pharmaceutical companies finally found the magic pill for weight loss? While it's not magic, Orexigen Therapeutics Inc. has had positive results in their recent trials for Contrave, a new obesity drug.

In one trial, 48 percent of obese participants who took a higher dose of Contrave lost at least 5 percent of their body weight; only 16.4 percent of control participants (who were taking a placebo) lost comparable weight. In a second trial, 56.3 percent of those taking Contrave lost weight compared to 17.1 percent taking a placebo.

With a more than 7 percent difference between Contrave takers and placebo takers, the trials were above the FDA guidelines for weight loss drugs. (FDA guidelines state that there must be at least a 5 percentage point difference.) A lower dose of Contrave also showed positive results in trials.

Instead of blocking fat absorption like Orlistat (found in the over-the-counter drug Alli) or controlling appetite like Meridia, Contrave tackles weight loss from another direction. Contrave is a combination of Wellbutrin, a common antidepressant, and naltrexone, a medication used to treat addictions.

Existing weight loss drugs have some nasty side effects. Fat blockers, for example, can cause diarrhea and/or anal leakage. Orexigen states that Contrave was generally well tolerated by trial participants. However, possible side effects include gall bladder inflammation and seizures.

Orexigen plans to seek FDA approval for Contrave next year.

A little soreness after a good workout is expected. That slow-developing ache that comes knocking a day or two after a good workout is called Delayed Onset Muscle Soreness. As long as it's just a mild discomfort, it's normal. In fact, you should almost expect it, especially when you're starting a new activity.

But sometimes we go a little far and the aches and pains are a bit much. Non-medication treatments like ice packs, hot showers and massages can provide some relief. And medication certainly can help, but NSAIDs (such as Advil and Aleve) can lead to stomach upset and acetaminophen (as found in Tylenol) has been linked to liver damage. Though, as That's Fit recently told you, taking small doses of painkillers for exercise-related pain isn't that harmful.

Still I wonder, when you overdo your workout, how do you treat the aches and pains?

Remember, mild aches after working out are expected. But if the pain you're experiencing is sharp or severe, it may indicate an injury and you should see your doctor. Speaking of workouts, have you ever considered working out at the beach?

Poor knees. They carry around our full weight every day. And knees that are attached to an overweight body are working overtime.

In addition to heart disease, diabetes, and other conditions, obesity can put you at risk for knee injury and conditions like osteoarthritis. Osteoarthritis is a degenerative musculoskeletal disorder that usually develops slowly, but obesity can cause rapid deterioration of the cartilage in the knee. Once you develop osteoarthritis, there's not much doctors can do; treatments revolve around managing the pain, and severe cases may require knee replacement surgery.

Over 300 patients who were at risk for osteoarthritis participated in a recent study. Weight proved to be a big factor in tissue decline; for every one unit increase in body mass index, the chance for cartilage loss jumped by 11 percent.

Odds are, if you've had to lose weight in the past, some of those lost pounds have crept back on at one time or another. That yo-yo cycle of dieting is never fun. Can you imagine if your job actually required you to gain and lose pounds? Many of the Hollywood set have had to adjust their weight for a role, but Renee Zellweger just might be the queen of the doughnut. With the third installment of the Bridget Jones's Diary series in the works, Renee Zellweger is gaining once again.

Zellweger gained roughly 28 pounds for each of the first two movies. Certainly not enough to make her tiny frame overweight by any standards -- in fact, she looks downright cute as Bridget Jones. But gaining 28 pounds probably isn't as fun as it seems. "I had a panic attack with all the specialists talking about how bad this is for you long-term, putting on that much weight in short periods of time," Zellweger told the Daily Mail. In fact, Zellweger has described her body as "whacked" after putting it through the Bridget Jones weight gain. "It doesn't know what has happened because it thinks there's supposed to be a baby and there's no christening," joked Zellweger.

For the first Bridget Jones movie, Zellweger gained the weight by eating as many doughnuts and cheese pizzas as her body could take. Not surprisingly, the junk food and lack of exercise made her feel sluggish. For the second movie, she hired a nutritionist and gained the weight with a controlled, but high-calorie, diet.

Losing the weight again was no bed of roses, either. Zellweger said that she felt like she had a toddler strapped to her back while running around the track. Obviously, Zellweger has the funds for trainers and the expensive Ashram Spa in Calabasas, Calif., but the hard work required to lose the pounds was all hers.

If you could earn a Zellweger-like salary, would you be willing to gain and lose weight repeatedly for work?

Grilled food is simply delicious and compared to other cooking methods like frying, it's generally healthier. But grilled food is not without a caveat. When the high heat from the grill hits the meat, cancer-causing compounds called heterocyclic amines (HCAs) are formed.

According to a post at CafeMom, a tasty trick can minimize the chances of HCAs forming. Just use antioxidant-rich herbs such as rosemary, thyme, sage or oregano in your marinade before grilling. Besides adding a layer of safety, marinading your meat makes it tastier. In addition to the fresh herbs, other healthful ingredients for your marinades include olive oil, fresh citrus and balsamic vinaigrette.

Remember, meat isn't your only option for the grill -- try grilling an all veg dinner or try some of these creative grilling ideas. AOL Health has more tips for safe, healthful and tasty grilling.

Khloe Kardashian after her 20-pound weight loss. Photo: Charley Gallay, Getty

It's not surprising that fans might label the Kardashian sisters in order to tell them apart. After all, they all have "K" names (Kim, Khloe and Kourtney), they all have gorgeous dark hair, they all appear on E!s "Keeping Up With the Kardashians" and they all have attitude. But when fans would stop Khloe Kardashian, they'd say, "Oh, you're the fat, funny one," Khloe recently told Life & Style magazine. Not exactly a label Khloe was looking for.

Weight struggles aren't new to Khloe. After her parents' divorce, emotional eating caused her to gain weight. "You just don't understand stress like that when you're younger," she says. As a teen, Khloe's unhealthy relationship with food went to the other extreme. "I was anorexic when I was 15 -- I'd be obsessed with working out, and I'd never eat," Khloe says in Life & Style. As an adult, emotional eating after her father's death caused her to gain weight once again.

Khloe started working out with her sister, Kim, and they'd work together to keep their snacking habits in check. Recently, Khloe Kardashian lost weight by exercising 45 minutes five days a week and eating healthfully. It sounds like a healthy and balanced approach to weight loss. However, Khloe claims that she lost 20 pounds in four weeks, and that's a bit hard to believe.

Eggs are rich in protein, nutritional powerhouses and considered superfood. While relatively high in cholesterol (about 212 mg in a hard-boiled egg), in moderation, they won't do any harm. In fact, research has shown that eating up to seven eggs in a week doesn't increase your risk for heart disease.

A hard-boiled egg is a convenient and energy-boosting snack. But how many calories are in a hard-boiled egg?
