The ex-couple still spend time with each other
The pair were snapped stretching side-by-side on a hilltop at the Malibu Rocky Oaks Estate Vineyards in Malibu on 14 February.
Both had dressed down for their work-out session, with Kris, 58, donning a black jacket and sunglasses and Bruce, 64, in a dark T-shirt.
They headed off in separate vehicles after exercising together.
Kim Kardashian‘s mum and stepfather announced they were ending their 22-year marriage in October.
They said at the time that they were ‘much happier’ living apart but would always have ‘much love and respect’ for each other and would ‘remain best friends’.
Since their break-up, Bruce has attracted a lot of attention for growing his short hair long, appearing to have plucked eyebrows and undergoing surgery to flatten his Adam’s apple.
A chondrolaryngoplasty – or a tracheal shave – is usually performed on patients in the initial stages of gender reassignment surgery but Bruce insists he ‘just never liked his trachea’.
