The Desperate Housewives alum took to Instagram on Tuesday to show off her progress with two revealing, full-body bikini shots after taking part in an eight-week fitness program ahead of her 55th birthday.
"Exercise has become a source of well being not a means to look good naked," she captioned the shots of herself in a brown two-piece suit, flexing her biceps. "This is my truth and being in this 55 year old body actually feels liberating. Here’s the thing. I’ve finally figured out how to be comfortable in my own skin. Maybe not every day but a lot of them."
Hatcher added that she "may not ever wear" a bikini again, but noted, "Being open to others, open to life... finding glorious connection and community. No filters, no makeup, no airbrushing, no negativity. Be strong enough to be vulnerable."
Hatcher first announced her eight-week fitness challenge back in October, working with the F45 gym to "get in great shape for my upcoming 55th birthday."
Another project Hatcher could possibly tackle at 55 is a Lois & Clark revival. Back in September, ET caught up with her former co-star, Dean Cain, who said he'd spoken with Hatcher about a possible reboot of their hit series.
"She agrees that it would be a great idea. I just don't know if we agree on what should be happening, which is perfect for Lois and Clark," Cain admitted at the time.
