Age is nothing but a number forMartha Stewart.
The 77-year-old lifestyle guru clapped back at a fan on Friday after sheposted a photo of herself riding a bicycleand was criticized for being “too old.”
Refusing to let her age define her abilities, Stewart directly responded to the fan — and garnered more than 880 Instagram likes in the process.

Back in March 2017, Stewartrevealed her tricks to looking youthful. “A healthy, good life, and good genes,” she said onThe Dr. Oz Show. “I mean, my mother’s skin was pretty smooth at 93.”
“I don’t sleep too much. Every morning at 4 o’clock when I wake up, I put a mask on. Any kind of mask. I have gingko, I have gommage, I have collagen. I have all of those masks,” Stewart continued. “Then I go back into bed, and I leave that on until I get up to go shower. It’s very good for your skin. It’s hydrating. I put it on my décolleté, so you look nice, and on my hands.”

As for what she puts in her body, Stewart explained that she relies on her famously green thumb.
“I drink green juice every single morning,” she said. “And I make it out of vegetables that I grow, in the greenhouse in the winter, in the garden in the summer. And they’re organic vegetables.”
“I eat well,” Stewart shared. “I don’t eat a lot of meat, I’m more of a fish-based diet. And I exercise as much as I can, so this week it was four days so far.”

The author has also previously expressed how shekeeps up with a routine of good eating and fitness— which she said includes hitting her home gym with a personal trainer at 6:30 A.M. daily.
“Convenience food is just not in my vocabulary,” she told PEOPLE in 2009. “Yoga is incredibly relaxing, but strenuous, too.”
But for those who can’t afford their own trainer, she revealed a favorite budget-friendly fitness alternative: cleaning.
“I’ve never had a housekeeper and I never will,” she said. “Cleaning does it for me.”
