Heather slipped her feet into a pair of fuzzy black slides and carried a her black shirt in her hand after the class.

She shielded her eyes and makeup-free visage underneath a pair of lightly tinted oversized black shades. 

Mrs. El Moussa tied her bright and shiny locks in a messy topknot bun as she toted her phone in one hand.

Before the class she was spotted heading into the studio with a cropped black shirt on and a beverage in her hand.

After working up a sweat with her spouse she reemerged in just her supportive, low-cut bra.

For his part, Tarek, 41, was prepared to hit the gym in a blue T-shirt, black shorts and a black hooded sweatshirt.

He added a black hat and he looked comfortable in a pair of casual black thong sandals.

After their Saturday activity Heather appeared on Instagram to share a selfie with her three million followers.

She and her husband posed inside their vehicle, each smiling while donning black shades.
