Una Healy has admitted her fitness is ‘absolutely shocking’ nearing the end of summer as she made a pledge to get ‘back on the fitness buzz.’ The former Saturdays singer turned solo star took to Instagram on Tuesday evening to document her first 5-kilometre run ‘in a long time.’ The Tipperary native shared that her children returning to school on Wednesday was giving her motivation.

‘I don’t know about you all but my fitness is absolutely shocking at the end of the summer,’ she said while out and about, ‘Kids are back to school tomorrow so I made a start to do my first 5k in a long time.’ Unfortunately, it wasn’t as easy as just getting out for the 5km, with Una telling her followers she ‘got to 1.3 kilometre’ before having to stop with a stitch.

‘Back on the fitness buzz now,’ she shared, revealing her plan for the rest of her run was to walk for a bit and then try and complete the run. The singer followed up to give an update on how her second go of running went simply saying: ‘No’ before revealing a second stitch had caught her. ‘It’s terrible to be unfit,’ she said, ‘Now, I’ve been going to the gym here and there but there’s no consistency so anyway.

‘Hopefully we’ll be back to fitness soon and yeah, watch this space.’ A post shared by Una Healy (@unahealy) ‘Maybe I shouldn’t have had lunch before I came out..
