Derek, who shot to fame as a pro hoofer on Dancing With The Stars, showed off his sculpted body as he lifted weights shirtless.

The 35-year-old beefcake wandered among the exercise machines that were strewn around the open garage where the group hung out.

Brooks could be spotted modeling a yellow tee as he worked out amid the group of friends, who have been spending time together lately.

The dashing ex-hockey player was previously self-isolating in Idaho but has since returned to Los Angeles and spent time with his friends.

Cory could be seen shirtless giving himself a grueling workout as he rode an exercise bicycle, clearly short of breath by the end.

Meanwhile Kristy was in a color-block pastel look that Brooks called the ‘workout outfit of the year’ and prompted Derek to refer to her as ’80s Kristy.’

Hayley, who also rose to prominence as a Dancing With The Stars pro, showed off her athletic build while exercising with her hair ‘blowin’ in the wind.’

Over the weekend Brooks was seen without his ring as he and a couple of pals including Cory stopped off at a house with a realty sign out front.

Brooks is still sporting a mohawk he recently got in Coeur D’Alene, the lakeside Idaho town where he and Julianne got married.

Last Thursday he, Cory, Derek, Hayley and Kristy all appeared on Insta Stories hanging out in the same garage they worked out in this Tuesday.

Meanwhile in the wake of her marital separation the formerly blonde Julianne died her hair pink this month and then went brunette.

‘Julianne’s not doing great right now and feels like her brunette hair is a reflection of her feelings. She is super upset,’ claimed an Us Weekly insider.

Julianne and Brooks announced their separation at the end of last month less than three full years after getting married.

The pair had been beset by rumors of marital problems ever since they went into lockdown separately amid the coronavirus  pandemic.

‘We have lovingly and carefully taken the time we have needed to arrive at our decision to separate,’ Julianne, 31, and Brooks, 36, told People together.

An insider told People they ultimately decided to split after discovering they were ‘perfectly happy and fine being apart’ while self-isolating in different states.

Two days before the separation announcement, Brooks posted ‘THIRST TRAP!’ shirtless photos from Idaho and Julianne commented that they were ‘awesome.’ 

A People source said Julianne is a ‘deeply different person than she was when they got married,’ and is ‘proud of those differences and changes she’s made and she doesn’t want to go back. He is the man he is and he shouldn’t change a thing. But they shouldn’t spend the rest of their lives together – not as spouses, anyway.’ 

During an Instagram Live interview with Oprah Magazine in April Julianne said of being in lockdown without Brooks: ‘I don’t feel lonely, but I definitely feel alone.’

Julianne, who has described herself as ‘not straight,’ was glimpsed in mid-April on a stroll with dashing 38-year-old English actor Ben Barnes who is an old pal of hers.
