Jessica Alba back to the gym after delivering third child!

Actress Jessica Alba is back in the gym six weeks after giving birth to son Hayes.

The actress and entrepreneur, 36, posted a photograph of herself, red-faced and sweating, next to her trainer Aaron Hines, here on Monday online, reports people.com.

"Got back in the saddle ... ish was hard. #6weekspostpartum thanks Aaron Hines, Cycle House and Tracy Dawn for motivating me," she wrote in the caption.

Hines also posted the same picture, writing, "First class back post-kiddo and she crushed it...Jessica Alba."

Alba and her husband, Cash Warren, welcomed their third child, son Hayes Alba Warren, on December 31. The newest member of the family joins Alba and Warren's two daughters: Haven Garner, 6, and Honor Marie, 9.

The action film star, and mom to daughters Honor and Haven says the key to balancing it all is just saying no to being burdened. "Don't be hard on yourself," she told Parents Latina.  "Doing your best to be present wherever you are is what's important." Amen!

The Girl Boss also recommends working mamas take some time out for themselves on the regular. "It's worth it to recharge once in a while," she explained. "Get sleep, have a girls night out." 

Truly inspiring for working-moms!
