Katharine McPhee showed off her toned tummy while sharing a glimpse of her workout routine on Instagram this week.
The 40-year-old singer, who is married to 74-year-old David Foster, used the app’s Stories feature to upload a video of herself undergoing a rigorous Pilates workout.
She was wearing a black Alo sports bra with white trim and matching skin-tight leggings.
The songstress wore white and black Alo Yoga socks and used the fitness equipment without shoes.
“Thank you @marymillermethod @alo. The socks are my favorite,” McPhee captioned a mirror selfie.
Katherine sported a loose bob hairstyle with blonde highlights that fell over her shoulders while hitting the gym.
She also wore jewelry that included a gold chain necklace and matching small earrings.
The mother-of-one, who has three-year-old son Renee with Foster, accentuated her look with stacked gold bracelets.
The star was makeup-free even as she sweated through her challenging classes.
The footage showed her squatting, lunging and stretching, using her core muscles to maintain balance.
Last fall, the entertainer admitted that she and her husband sometimes disagreed when it came to raising their son.
“I want to start being disciplined. [Rennie] “Kat’s not into that sort of thing,” her music producer husband told People magazine in November.
McPhee explained, “No, that’s not true. I just want to discipline my kids my way. I just have a different approach. I think he was raised in a different era than I was.”
She explained: “There are also more traditional methods of discipline, including time-outs.”
“In my opinion, we can parent more mindfully rather than simply assuming that a two- or three-year-old can have time alone to reflect on their mistakes.”
The singer-songwriter added: “I think the newer way of parenting is understanding that there’s only so much a child can understand intellectually.”
The two met in 2006 when Foster served as a guest mentor on American Idol.
The two began dating in 2017 and married in June 2019.
