Maria M. Kang-Casler (born 1980 in San Francisco, California), is an American fitness advocate, coach, blogger, and founder of the No Excuse Mom movement, a nonprofit organization which promotes a healthy lifestyle, centered on diet and exercise, for mothers.

In January 2014, Kang founded No Excuse Mom and made appearances on local and national media to opine on lifestyle issues.

Kang's mother, Caroline, the daughter of Philippine diplomat George G. Aducayen, Jr., from Cagayan[2] married at 16 and had four children, one boy and three girls, by the time she was 22.

Kang's Malaysian Chinese immigrant father, Francis, was a police officer while Caroline worked full-time managing a state-owned parking garage.

[3][4] As Kang grew up, her mother Caroline suffered from numerous health-issues related to her being overweight, including diabetes, heart attacks, a stroke, and kidney failure.

Soon after, at a photo shoot at a pool in Los Angeles with other bikini models, Kang felt that the atmosphere and presentation had crossed the line into softcore pornography.

[3][2][7] By 2012, Kang had given birth to three sons and appeared several times on local TV programming as an advocate for fitness activities and healthy diets for children.

[6] She had continued to lead the free workouts at the park and publicized her fitness group to about 50 followers on a Facebook page on which she made frequent posts with advice on exercise and diet.

In an effort to gain a wider audience and motivate people to make fitness a priority, on August 25, 2012 Kang had a professional photograph taken of her posing in a sports bra and exercise shorts with her three sons.

[10][11] On September 26, 2013, Kang reposted [12] the photo on her Facebook page with a non-apology apology for the original post and added a short editorial on the obesity crisis.

[13][14][15] This time, the photo went viral, being reposted, shared, or linked to on thousands of other Facebook pages and over other social media mediums and forums, resulting in 16 million views within a few weeks.

[16] Several editorials that accused Kang of fat shaming or being an unfair beneficiary of privilege were penned in The Huffington Post and feminist blog Jezebel.

Said Kang on her Facebook page: I woke up this morning to news stories about how overweight, nearly obese women should be proud of their bodies (as they posed in lingerie).

[33] Both Kang and Bougon were subsequently invited to give their respective side on the disagreement by speaking or being interviewed on CNN,[36] Good Morning America, Access Hollywood,[33] and The Dr. Oz Show.

[41][4][7] Through her website, Kang sells fitness-related instructional and workout DVDs and calendars featuring photos of "fit moms" from her program.

[3][42][43][44][45][46] Kang has made further appearances in the media, including as co-host for a periodic segment on KXTX's News10 called "What's Buzzing," usually to comment on living a healthy lifestyle.

[3] Her husband, David Casler, who suffered a combat-related traumatic brain injury while working as a private security contractor in Iraq, volunteers for Team Rubicon.
