Experience working with LDD has shown, quite often, they don’t feel comfortable in a gym environment.
Also, through discussions with people with LDD, they felt overwhelmed or the personal trainers didn’t cater for their needs
Therefore, the charity I volunteer with, decided to help someone with LDD, in their own homes, to get fitter due to health issues.

The person involved has improved their health, and their progress will be shared. Also the charity is looking to expand this service.
