The groups, run by Step into Life Glenbrook owner Justin Lavender, have been moved on by the council three times since February following the complaints.

Mr Lavender and his group have become exasperated by the continued relocations.

“It’s not like we’re going round throwing beer bottles at places and music up loud or anything, we’re trying to all get fit and do something right,” Mr Lavender said.

Sessions have so far been moved from Glenbrook Oval to Glenbrook Park then to Lennox Park and now back to Glenbrook Oval.

The set of portable lights stand at about 1.5m and Mr Lavender said they generally cover an area of around 30m by 15m. He said the sessions are finished by 8.30pm.

“Honestly, it’s not all that bright . . (and) it’s not like they’re facing in towards the houses.”

Mr Lavender is confident after speaking with the council and Glenbrook Oval’s other tenants that he will be able to continue having sessions at that ground.

“(The council) said they want me to keep going because I am doing something for the community and (my clients) are obviously seeing the benefits of coming down and doing it too.”

One of Mr Lavender’s regular clients, Michelle Gawthorpe, said she was disappointed by the complaints.

“It was an inconvenience, always having to move just because of lights that weren’t even directed at people,” she said.

A council spokesperson said following the complaints against the Step into Life groups, it had asked Mr Lavender to modify the way the lights are used and said they will continue to monitor the situation.

In response to the relatively new phenomenon of commercial operators running training sessions in Mountains parks, the council is introducing new policy to regulate the practice.

The spokesperson said the council does not object to personal trainers using the parks but that the new policy will formalise the use by asking operators to make bookings and also pay a fee.
