Did you spend all your money on summer clothes, but want a star’s body? Try this simple (and free) park workout!

If you’re like me, the last thing you want is to spend your hard-earned money on a gym membership. Luckily, the weather in the summer is perfect for using the great “outdoors” as your fancy gym. All you need for a workout fit for the stars is 15-45 minutes, some workout clothes and — if you’re ambitious — a jump rope!

In addition to some new cardio moves, this week I also focused on heart rate. You always hear about “target heart rate” zones, but did you realize if you push too hard — or not enough — you’ll not burn the maximum amount of fat? Since I wasn’t on a machine that could help me count my heart rate, I tried out the MIO Energy Pro watch, which gave me my heart rate with just a touch. Check it out here.

From January Jones to Pink and Bethenny Frankel to Selma Blair, all the A-list moms and mommies-to-be in Hollywood agree: prenatal yoga is the hot new pregnancy trend! We decided to talk to an expert to see exactly what this new workout craze is all about! 

“Prenatal yoga classes are more popular than ever,” Lisa Druxman, fitness expert and founder of Stroller Strides, tells HollyBaby.com. And there’s a good reason the stars choose yoga to keep the weight off! “Moms are looking for ways to stay fit during pregnancy and yoga is an excellent choice.”

Since the needs of a pregnant woman are constantly changing, one of the best aspects of prenatal yoga, Lisa says, is its flexibility. “Clients appreciate knowing that their instructor is well versed on what they can and can’t do and can modify for different stages of pregnancy.”

Not only are there health benefits, “prenatal yoga helps with strength, flexibility, balance and circulation – all which are important during pregnancy.” There are also social benefits!

“I think prenatal yoga and other prenatal classes are excellent because you meet other pregnant moms,” Lisa says. “They help you know what to expect and you benefit from instructors who are knowledgeable about your pregnancy.” We know that’s true! That’s the reason Selma and Ali Landry have grown so close!

Yoga also pays off in the long-run, the breathing exercises used during yoga can also be applied during labor.

So there you have it HollyMoms! What do you think? Is prenatal yoga something you’ll be trying?

Kids? Whatever. These celebrity mamas have never looked better — they have abs of steel! But whose are the best?

41-year-old Jennifer Lopez showed off her rock hard six-pack last night, May 5, in a performance of her hit song “On The Floor” on American Idol. So we decided to put her abs to the test! It’s time for a mommy face off — who has the best toned tummy?

From workout-aholic and mom-of-two Gwen Stefani, 41, to Victoria Secret Angel mommy Gisele Bundchen, 30, to Sex and the City star Sarah Jessica Parker, 46, we found some of the best sets of mom abs in Hollywood.

But tell us, who sports the best abs?

Like every woman, Gwyneth Paltrow has a trouble area on her body that always drives her nuts. For Gwyn, her butt has never been to her liking — until the day she met her trainer Tracy Anderson!

“My butt! My butt, butt, butt,” the 38-year0ld actress turned country singer complains when SELF magazine asks her where he problem area lies.

But Gwyn’s wish of fixing that problem has finally came true. “When Tracy met me, she said that I had a long, square butt that she was going to redesign, and I was, like, ‘Yeah? Good luck,’” Gwyn remembers. “The amazing thing is, she was right! And it’s still changing!”

So how does Gwyn keep her amazing bod in shape? “I do 45 minutes of cardio five days a week, because I like to eat,” she says. “I also try for 45 minutes of muscular structure work, which is toning, realigning and lengthening.”

And when she’s getting ready to do movie or an appearance, Gwyn’s workouts get more intense. “If I’m prepping for something or I’ve been eating a lot of pie, I do two hours a day, six days a week for two weeks,” she admits.

“I’ve found what works for me,” she continues. “I know if I put in an hour and a half, five days a week, I’m good.

But like everyone else, sometimes Gwyn slips up. “If I’m on vacation and, like, ‘F**k it, I’m not working out,’” she confesses. “I know what to do when I get back.”

“I never thought that I’d be considered to have a good body,” Gwyn says. “I was bony up top and kind of dumpy on the bottom. But my trainer, Tracy, completely changed my legs, butt, arms and stomach. I feel better than ever, too.”

And Gwyn encourages women that they can get past that invisible brick wall that holds them from reaching their potential.

“A lot of women think, ‘Oh, my God, I could never get there,’ but I don’t think that’s true,” says Gwyn. “It’s simply relative to how much you put into it.”

“I go with my instincts,” she adds. “We’re capable of pushing ourselves and doing whatever we want to do. You live one time, so be your best self.”

Kourtney, 31, claims she lost all her baby weight quickly after giving birth to Mason 15 months ago, by carrying her son everywhere she went — even using him as a gym accessory!

“I take Mason on lots of walks. Carrying him around him around is like carrying 20lbs all day,” Kourtney tells Look magazine, adding, “When he was a baby I’d do squats while holding him.” We’d love to see that in action!

But the reality TV star insists her cute tot can’t take all the credit for her fabulous figure — she combined her new fitness routine with a new healthier diet, “I was eating a lot of dried fruit and I didn’t know how much sugar that added. And now I’ll eat raw almonds instead of salted ones.”

But she’s not good ALL the time! “I’ll eat Oreos,” she says, “but I’ll eat two instead of a whole box of them. I think you have to treat yourself once in a while.”

There are many expectant mommies out there who refuse to give up their workout routine — just like Jessica. Good for them!

Jessica Alba may be expecting baby number two (with hubby Cash Warren), but that hasn’t stopped her from getting her sweat on at the gym. It looks like the actress, 29, feels energized and excited about working out throughout her pregnancy — and an expert says that’s good for not only her, but her baby!

“Exercise during pregnancy can alleviate almost every known discomfort of pregnancy,” Fitness Expert and Founder of Stroller Strides Lisa Druxman tells HollyBaby.com. “Your risks of gestational diabetes, hypertension and obsteric interventions decrease with exercise. Your labor is likely to be lessened and you will have a lesser chance of cesarean,” she adds. “Best of all, you’ll feel better if you exercise during pregnancy.”

Lisa encourages pregnant women to workout for 30 minutes most, if not all days of the week — whether it be cardio or yoga.

“Just like the non-pregnant woman, a combination of strength, cardio and flexibility is preferred,” Lisa explains. “Consistency is most important as it is not good for you or the baby to jump in and out of workouts. If you workout a few times a week, then you want to keep that up throughout the pregnancy.”

The only kinds of exercise that expectant mommies should be cautious of are ones where you could fall (such as skiing) or could get hit (such as boxing). Sounds practical!

And the even better news is the post-baby weight will melt off if you keep up a nice fitness regimen.

“Women who workout during pregnancy tend to put on less weight and definitely take it off faster than those who don’t!” Lisa says.

So Jessica has the right idea. What’s your take on this?

Nothing cuter than a dad and his son sporting matching outfits, especially when they accessorize with the gorgeous Gwen Stefani!

All that’s missing in this photo is 2-year-old Zuma! Gwen Stefani, 41, her husband Gavin Rossdale, 45, and their son Kingston, 4½, were quite the trio in Los Angeles, CA on Sunday (March 6). The two dudes looked dapper in denim — they even wore matching shoes!

Gwen, who looked equally as stylish in her harem pants and leather bomber, recently told UK’s Elle Magazine that keeping her svelte figure is “a daily struggle” that comes down to an intense workout regimen.

“I work out five days a week, I can’t imagine not doing it,” the mother-of-two explains. “I’d like to have no rules and eat what I want, but I’ve learned over the years that I’m so disappointed when I can’t wear the clothes I want to wear,” she adds. “And if I let myself down, appear on stage when I’m not looking my best, it’s not fun for me. I just beat myself up about it.”

Well Gwen, you look pretty amazing to us, and so do your matching men!

Family fitness! Look at little Vida doing squats with her daddy. This is the cutest way to burn calories.

Looks like Matthew, 41, won’t be only McConaughey with rock-hard abs! The actor’s tiny tots watched him intently as he began his workout routine. They even mimicked some of his moves! Funny thing is, it looks like Levi, 2, and Vida,1, are into squats. This family loves to feel the burn together!

Matthew McConaughey and his diapered-up beach babes!

While Vida squatted alongside her buff daddy, Levi decided to try out some of his own moves and just go with it. When it came to push-up time, the kids were much happier gazing at their dad’s sculpted body rather than actually participating. Levi figured snack time was much better than workout time. Personally, I think he has the right idea. But we are sad to see that Matthew kept his shirt on for the entire sweaty session.

After a tough workout, Levi and Vida relaxed in their double stroller as Matthew pushed them along Zuma Beach in Malibu for his seaside run.
