Laura Prepon transformed her life and health since overhauling her diet (and writing a book about it!). Prepon, 44, shared a video of herself wearing black leggings and a gray sweatshirt, doing a variety of low-impact, gentle strength training exercises at the gym. "I always try to get in a sweat before work… what gets you ready for the day?🏋🏻‍♀️ #GetYourPrepOn #PrepOn," she captioned the post. "Thank you for showing us your exercise routine, you encourage us 💕😍❤️," a fan commented. Here's what Prepon's wellness routine looks like. 

Prepon and integrated nutritionist Elizabeth Troy wrote a diet and wellness book called The Stash Plan. "It was one of those kismet things where I knew she was going to heal me and that's what happened," she told PEOPLE. Under Troy's guidance, Prepon switched to organic, gluten-free food to help her liver and gallbladder. "As long [the food] hasn't been altered I'll eat it. I put brown sugar in my tea. There's nothing wrong with sugar. You have to be able to have fun and live your life."

Prepon swears by her Vitamix blender for healthy food prep and cooking. "I love this blender for soups and smoothies," she told Equinox. "It's so easy and you feel like a professional chef when you use it. I'll take the broth I've made in my slow cooker and throw it in my Vitamix with steamed butternut squash or other veggies and make yummy pureed soups. Or I'll throw in a bunch of raw fruit, ice, yogurt and blend up a great smoothie."

Prepon likes to go old-school when it comes to her workout routine. "My friends make fun of me because I still use my iPod Shuffle…haha!" she told Equinox. "But I love this thing. I don't like having a bulgy iPhone to carry around or put in my pocket when I'm at the gym. I get 10 hours of music and it's great for working out."

Prepon makes her own home-made bone broth. "I love my slow cooker," she told Equinox. "When I get home to L.A., the first thing I do is get a bone broth cooking. This is an essential part of my lifestyle. I always have a broth in my fridge and my slow cooker is the key to that."

Prepon replaced her high-intensity gym sessions with stretching workouts. "I'm in the best shape of my life," she told PEOPLE. "Once we had the breakthrough with the stretching in combination with the food, it legitimately changed everything for me. I worked out more than anyone I knew! Now [stretching is] the only workout I do."
