Riverdale Star Madelaine Petsch Shares Swimsuit Photos of "Summer"

Riverdale star Madelaine Petsch is already missing the summer sunshine, judging by her recent social media posts. Petsch, 29, shared highlights of lots of summer fun spent with friends, traveling and enjoying delicious food. She also posted a selfie where she's posing in front of the mirror in a black and white bikini and black skirt. "Summer imy [I miss you] 🥲," she captioned the post. "Can we run it back?" a friend commented. Petsch earns her fun by working hard the rest of the time—here's how she does it.

Petsch works out with a personal trainer who puts her through her paces. "The body part I love exercising the most is my abs," she says. "I think that my abs feel the most pain and I love the feeling of being sore. My trainer does this thing called six-minute abs, which is honestly deathly. They are the hardest thing ever. He doesn't tell me what it is, every minute or 30 seconds he'll switch to a new thing but he'll never tell me because then my brain can't anticipate it. I can still feel my workout in my abs and that is *chef's kiss* a beautiful thing."

Petsch enjoys vegan red lentil pasta for protein and taste. "Protein is something I really have to be aware of in every meal or else my energy levels just go completely downhill… I really like protein pasta because I'm such a carb fan," she says. "I need to hit my salivary glands and I also need to hit my protein."

Petsch was raised in a vegan household. "I've been plant-based my whole life. Being vegan keeps my body fueled and running smoothly," she says. "I exercise for an hour and a half: a 2 to 3 mile run, and then muscle training. I eat [overnight oats] everyday! I'm not always able to plan ahead. My diet works for me because I can be very flexible about what I eat in a day. I eat clean and non-processed food, which helps me avoid feeling fatigued on long workdays."

Petsch always makes time for self-care. "I have a personal trainer out here in Vancouver, and I love training with her," she says. "And then afterward, I'll come home, I'll put my phone on 'do not disturb,' I'll put on one of my favorite playlists, I'll light a bunch of candles, I'll make a bubble bath, and I'll bring a book in there—it's a whole thing. I have my robe on, I have my diffuser going—I really love my alone time as well. I also like to go to bed early—it's a treat to me. Or even making a YouTube video and editing it."

Petsch keeps her looks as simple as possible when she's not working. "I think I always had the idea that less is more when it came to makeup," she says. "I remember watching my mom getting ready in the morning, and she would put just a little bit of gold eye shadow on her eyelids and a little bit of mascara and that was it. You know when you're young, you look up to your mom, and I remember always wanting to do whatever she was doing when it came to her makeup."
