Shah Rukh Khan, who flaunted six-pack abs in blockbuster Om Shanti Om but couldn't maintain them later, is doling out fitness tips to youngsters through micro-blogging site Twitter.
"Six-pack has more to do with diet than exercise alone. You need to be very disciplined. (Do it for) 30 to 40 days...they will start to show," Shah Rukh posted on his Twitter page on Monday.
"Exercise regimen - four times a week. Thirty minutes do a weights or any exercise which makes you sweat. No rice or bread at all with food, grilled food. Lots of water. No alcohol. If you do, then exercise (for) 50 minutes. No music and wasting time during exercise. Just do it like a job...push yourself."
"No desserts, ice creams or colas. No food in between meals like chips, etc. Singlehandedly try and bring the junk food industry to closure," he wrote.
Shah Rukh says he does 100 push ups and 60 pull ups when he is regular. "When I start I can only do five push ups and one pull up. It just happens (later) if you are regular," he posted.
The actor, who was last seen in My Name Is Khan, is strictly against quick fix diets, and says people must make a careful choice about what they eat and drink.
"You make your choices according to your needs. When I work out I don't drink colas myself."
