FORMER fattest man in the world Paul Mason pumped iron in a gym for the first time this week - and said: "I could really get into this!"
The super slimmer has lost 46st of his 70st bulk and aims to shed more by working out four times a week.
He praised The Sun for giving him the confidence to visit the health club by telling the story of his amazing weight loss last week.
Paul, 51, tried exercise machines as he toured the David Lloyd fitness centre near his home in Ipswich, Suffolk.
He said: "I'd been thinking of joining a gym for a while - but I only decided to go for it after my story appeared.
"I am grateful to The Sun for giving me the confidence to be here today. I want to come here regularly and get really fit."
Ex-postie Paul, who ballooned after eating 20,000 calories a day, needs his doctor's permission to take up gym membership. But he said: "I'm sure he'll be OK. I feel I have a very fit body inside me."
Paul slimmed to 24st after a gastric bypass and has set a new target weight of 14 or 15st.
But he says he now needs a £30,000 (F$85, 500.68) op to remove loose skin.
