Michelle Obama has taken to Instagram to share her “self-care”sunday which displayed her famous biceps. 

The former first lady, 55, was photographed holding a large and weighty medicine ball over her head while blaring her abs in matching black sports bra and leggings. 

The mother-of-two says she is all about having a “no pain, no gain” mentality in order to succeed. 

“It doesn’t always feel good in the moment,” she explained while talking about her work out. 

“But after the fact, I’m always glad I hit the gym.”

The post has raked in over 1 million likes and had over 21,000 comments filled with supportive bicep emojis. 

“You put me to shame,” wrote on admirer, while another said: “Come on mama!”

“So proud of you Michelle,” another fan wrote before adding: I’m going to plank because of this post.”

While many praised Michelle for her “inspiring” body, others joked their #SelfcareSunday looked a lot like a big hearty breakfast and a good sleep in. 

In her memoir Becoming, Obama wrote her regular workouts and healthy eating allowed her to maintain a work-life balance as a working mother.
