Pas' candidate Dr Zulkefli Mohamed remained a good sport over jokes that his stocky frame might tire him fast during the campaign trail.
He said he was used to work long hours when he was a doctor at government hospitals in the past.
"There were times when I had to work over 36 hours on a stretch, then. I think I can keep up with the hectic campaign schedule now," he said.
Dr Zulkefli, 44, will be up against Barisan Nasional's Abdul Aziz Yusoff, 49, in the Galas by-election on Nov 4.
Some segments of political watchers have been heard making comparisons between the two candidates of their physiques.
Such light banter follows an absence of substantive issues to debate since campaigning started on Nov 26.
Dr Zulkefli said he was feeling alright even when there were many places to visit over the past three days.
To keep fit, he said he took a lot of water and sufficient rest.
When a reporter asked about his weight, Dr Zulkefli said: "I do not know. Let us keep it as a secret."
In jest, he said he could take on Aziz in a running or tug-of-war competition.
