Gym users turned out in force and flexed their fundraising muscles to help the family of Jacob Jenkins.
Members of Crossfit Telic gym, on Hartlepool’s Parkview industrial estate, raised more than £500 for the cause which has touched the whole town.
They pushed themselves to the limit in a punishing three-hour sponsored workout session.
Non-gym members also went along to offer their support.
Crossfit Telic Hartlepool co-owner Lee Howe said: “The charity day was a huge success and we raised £583 for the Jacob Jenkins charity.”
The gym held the community day when non-members were invited to get a taste of the facilities with a free induction and fun workout, and also support the fundraising.
Crossfit combines numerous exercise disciplines including weights, rowing, gymnastics and jumping.
During a similar event last year the gym raised £300 for bowel cancer support, which was then doubled with match-funding.
