This is going to be a massive task and will require training that I have not been able to take since the 1980s.
It will require me to contact every local Gymnastics club that has an evening in the week that they allocate to adults who want to come in. Usually, it seemed to be free-running people the last time I tried to train. If I can find 4 clubs with one night in each, I can manage to get 4 lessons in per week.
Ideally, I would be able to find a coach that I could hire for 1 or 2 of those nights to give private instruction, but I wouldn't think that many coaches would want to take on an adult student in their 50's lol.
