My DS7 has poor core strength (according to swimming teacher) he also runs quite awkwardly the poor soul. He is not a natural sportsman and can be a bit lazy and would definitely not choose to be active unless I make him. What might help? I’m upping general activity in terms of going for walks etc and will try getting him running with me. He finds it hard to accept that it takes time (and effort!) to get good at things so I worry that obvious things like gymnastics are doomed to fail.
