To get an outdoor gym (like the one in Wester Hailes Quarry Park) installed at Portobello Beach, perhaps at the empty green space at the bottom of Malborough street.
This would encourage children and adults alike to keep fit as they do not have to pay expensive gym memberships, which some people cannot afford, and is in a place that many people visit daily, so they wouldn't have to travel too far to get to it. Also, it would greatly improve the health of people with mental health issues and would motivate people to be less lazy.
This would also encourage more people to come to Portobello, which would help business owners.
