Jenna Dewan in Two-Piece Workout Gear Shares "My Secret Weapon"

Jenna Dewan is showing off her pregnant body while doing pilates. In a new social media post the actress shows off her baby bump in a tight black workout ensemble while on the reformer. "My secret weapon forever," she captioned the Instagram Stories clip. Aside from doing Pilates – which "strengthens the body's inner core while increasing its flexibility resulting in improved overall health," per the Mayo Clinic – how does the actress stay in shape? Here is everything you need to know about her lifestyle habits. 

Jenna maintains that resting is a key aspect of overall health. "Rest is the hardest thing for me to come by, as I'm sure most people can relate, but I try to get as much as I can," she recently told Shape magazine. "Making time for myself within working, within family, within all of that is very, very important for me and not the easiest to do, but I make it a priority."

Dewan is a big fan of taking "me time," she told Shape. One of her go-to methods is taking a bath. How can baths do your body and mind good? They have been linked to better sleep and even found helpful to minimize anxiety and depression. One recent study even found that they may even boast cardiovascular benefits.df44d9eab23ea271ddde7545ae2c09ec

Jenna maintains a plant-based diet. "I've been vegan before and I kind of went vegetarian while pregnant. But I really like [to get] as much vegetables and greens as possible, and then add in on top of that. I try to do an 80-20, 80 percent really good for you, and 20 percent to enjoy what I want to enjoy. But right now, I've been in this cleanse stage, so in the mornings I like a green juice — like a celery juice or green smoothie — and I'll have a cup of coffee," she told POPSUGAR.

Dewan is fully "addicted" to weight lifting. "I'm into variety, so I like to switch it up because I get bored easily. Lately, I started with a trainer, which for me is new because I had been just doing Pilates or dance-based workouts or yoga. The trainer's been great for me. He's full-on — we're deadlifting, we're squatting. But I give him 45 minutes and I'm like: this is the time I have, make it worth it. And it's really helped. At the moment, I'm preferring to sculpt and build muscle, so I'm definitely into weight lifting," she told POPSUGAR. 

Jenna also loved danced-based workouts like Tracy Anderson. "With my career, there will be moments where they want a dance performance, so I end up back in the studio consistently, in different ways," she told POPSUGAR. For example, she learned to pole dance for her role in the movie "Let's Get Physical".
