The brunette star and former model was spotted keeping fit and still looking fab yesterday (25 February) at Sutton Park in Birmingham, along with her personal trainer Jamie Reynolds.
While being put through her paces by Jamie, Danielle showed off her toned figure in a pair of leggings and her red Sport Relief T-shirt, which matched her footwear.
She also opted to keep her long brown locks down instead of tying them back, while getting to grips with some stretching exercises on a nearby tree.
Danielle - who is married to footballer Jamie O'Hara - will be cycling a mammoth 25 miles on 23 March in a bid to raise money for the famous charity event.
And it's been all go at home too.
In between her gruelling workouts and Sport Relief prep, the 30-year-old has still been busy looking after her adorable three sons Archie, Harry and George and spending lots of quality time with the trio for half-term.
Last week, Danielle took her boys for a family day out to London and posed for a cute selfie with eldest son Archie.
She also uploaded a sweet snap of the tiny tots hanging out at home over the weekend and wrote: "My 3 little men drive me crazy but best thing to ever happen to me."
