No wonder she has a flawless bikini body!

Sports Illustrated swimsuit star Leticia “Tish” Martinez took to social media to flex her impressive core muscles, modeling athletic wear including a bright red sports bra and low-hanging joggers that flaunt her enviable ab muscles.

The fitness and workout guru and entrepreneur finished the look with sunglasses and a black sweatshirt draped over her shoulders.

“Out & about ✨,” she captioned the Tuesday, September 23 Instagram post. “wearing the new @oneractive Accentuate capsule…So obsessed with this drop.” She also gave a discount code and detailed the sweatshirt, joggers, seamless shorts (which appear as a coral strip under the joggers), and strappy sports bra.

She shows off her cut physique in a second photo as well, and a video of her walking.

“Hello abs,” wrote one commenter, immediately zeroing in on the trainer’s cut physique.

“Body goals,” agreed another.
