And Kourtney Kardashian proudly showed the results of her grueling sweat sessions when she stepped out with her son Mason on Tuesday.
The 37-year-old reality star slipped into a skintight plunging tank that highlighted her enviable figure.

Her low-cut top flashed a hint of her ample cleavage and sun-kissed skin as she walked her eldest child to his lessons.
She went with an effortlessly cool ensemble in distressed jeans by OneXTeaspoon which featured huge holes throughout the front, revealing her bronzed stems beneath.
Rounding out the brunette beauty’s look was a pair of chic taupe suede ankle boots and gold aviator shades.
The mother of three also shares daughter Penelope, aged four, and 20-month-old son, Reign with her estranged partner Scott Disick, 33.
After her mommy duties were complete, Kourtney headed home and shot some hoops with her younger brother, Rob Kardashian, 29.
She cheered the fiancé of pregnant Blac Chyna on as he threw the basketball towards the hoop.
