Britney Spears is putting her fitness first, even when she's on holiday.
The 40-year-old pop star revealed her fierce workout ethic on Tuesday evening, as she pumped iron in the gym, sharing a video to her 39.2m followers on Instagram.
However, Britney - who is currently in Hawaii with her fiancé Sam Asghari - confessed her struggles with staying motivated, telling her fans that she 'hates' running, but it's good for her abs.

She danced around in the barely-there bikini to the tune of Calvin Harris' How Deep Is Your Love.
Her newly-dyed purple hair was seen swinging behind her in a lengthy ponytail.
Though she's since changed the caption, she originally remarked that her bikini was from Target and that it used to be her 'favorite' but some unflattering
