The 'foodless snack' trend is about doing sort bursts of movement every 30 minutes or so through the working day to both break up desk-time and put you on target to reach the recommended 150 minutes' moderate exercise each week.

Federation University lecturer and exercise physiologist Matthew Wallen said being in isolation or restricted from a pre-pandemic fitness method did not mean giving up physical activity.

Dr Wallen, speaking in Compassionate Ballarat's webinar series, said doing some physical activity was better than doing no physical activity in a bid to stay healthy and as a therapeutic tool to help a range of chronic conditions.

"Something no-one had seen coming was the fluctuations in lockdowns - it's handy to always have something in your back pocket you can do at home," Dr Wallen said.

"Yes, it's fantastic to go back to the gym, but if there is still fluidity about gyms opening you need to have other options about Ballarat."

Lockdowns sparked sparked new waves of traffic running and walking about Lake Wendouree or cycling about neighbourhoods.

Dr Wallen said you did not need expensive equipment for a great workout and people should also aim to be as active as they can in as many possible ways about the house.

His suggestions included steps for strength and cardio exercises, laundry baskets for deadlifts, couches for bench work and hills for a good workout outside - but also to do something you enjoy.

But Dr Wallen also stressed safety and understanding your own body - consulting a GP or exercise professional if need - to ensure correct loading and intensity for your body.

Compassionate Ballarat's series continues on Wednesday with Creative City coordinator Tara Poole on the good and bad of COVID-19 on Ballarat, how to grow our social and creative lives.
