I’m your typical pretty girl until I stand up: ‘OMG muscle mommy!’

She lifts, bro.

Fitness influencer and TikTok user Riley — known as @riley_habel615 on the app — is going viral for her shockingly big arm muscles that have viewers doing a double take.

Earlier this month, the Boise State alumnus posted a video that starts with her squatting down close up to the camera.

Wearing a full face of glam makeup, silver hoop earrings, a black tube top and black ripped jeans, Riley mouths along to the audio that asks: “Do you feel bonita?” — the Spanish word for “beautiful.”

Then she’s seen taking a step back so that viewers can get a load of her formidable upper arms, flexing them for good measure as the audio tracking sings: “I feel bonita.”

“Wonderful,” chimes in the voice of Chris Griffin, of the cartoon comedy series “Family Guy.”

“Because you look bonita.”

The clip racked up 10.7 million views and more than 9,000 comments from impressed viewers on TikTok.

The Post has contacted Riley for comment.

In other clips on the video-sharing platform, Riley has claimed to work out for two hours daily and could bench any man who weighs under 200 pounds.

TikTok users have labeled her a “muscle mommy” — which, according to Urban Dictionary, is slang for “a woman with big muscle and that other girls look up to.”

“Muscle mommy has a whole new meaning,” one fan wrote.

Some admitted they were “not expecting” Riley’s muscles to pop like that.

Another trailed off: “When I say I gasped…”

Her jaw-dropping physique also drew comparisons to superheroes, suggesting she could be capable of anything.

“She gives [the] Hulk homework,” quipped one viewer, pitting her against Marvel’s muscley green giant.

Suggested another humble viewer, “Those jeans weren’t ripped when she put them on.”
