According to the Ministry of Health New Zealand has the third highest adult obesity rate in the OECD, and rates are rising. Almost one in three adult New Zealanders (over 15 years) is obese, and one in ten children.
Obesity leads to numerous health problems which can ultimately be fatal.
Mr Vaeoso intends taking the demonstration around the country following its debut in Whanganui on February 11.
Then in November, on the anniversary of Lomu's death, an attempt at a world record will be made at Eden Park for the largest aerobics class. The target is 48,000 people and will feature a host of New Zealand sporting legends.
"The Onyou challenge is the first event on a journery to beat obesity and build a healthier New Zealand," Mr Vaeoso said.
"Our plan is to create a movement led by New Zealand's sporting heroes to start lifting ourselves up by our bootstraps to create a healthier New Zealand for current and future generations - and have some fun along the way."
All Blacks, Warriors, Silver ferns and Black Caps, will put their bodies and reputations on the line and brave the stage carrying out choreographed aerobics routines, inviting all participants to join them in an attempt at the record.
Convincing the "Big fella" about aerobics was easy, Mr Vaeoso said. "We both love music and movement." He said Eden Park was a suitable venue for the record attempt as not only was it large enough but also paid tribute to Lomu.
Another All Black great, Michael Jones, had stepped up as Patron, following Lomu's death.
Rotary district govenor Bob Smith said Rotary had taken on the Onyou challenge as a national project.
