Proudlock posted a photo to Twitter earlier today (29 January) as he made a new personal best during his morning session at the gym.
Showing off his lean muscles, he tweeted: "Just had savage leg session with @DanCaseypt @thelomaxway. Hit my PB on deadlifts. #130kg."
Proudlock kicked off filming for the BAFTA award-winning reality show last week, joining the likes of Spencer Matthews, Binky Felstead and Alex Mytton for the new seventh series.
Proudlock was very much the voice of reason during series six, giving best mates Spencer and Jamie Laing much-appreicated advice on their relationship woes.
Proudlock's model girlfriend Grace McGovern didn't make an appearance in the show last year, but will she be making her screen debut for the seventh series?
The couple are still going strong, and earlier this week Proudlock shared a cute photo of the pair on Instagram. Serge DeNimes designer Proudlock, who got a tattoo of Grace's initals last year, wrote: "Chillin with my bubby @gracemcgovern."
