Ab Exercises: The Plank

im 15 yrs old and tried it for my first time and lasted 4minutes 53seconds

@bati555
work on your deltoids

@bati555: Same thing happens to me...

Keep going. Shows you need to work your shoulders.  Eventually your shoulders will develop so that they can hold you in the plank

How long should a beginner, intermediate, and expert be able to hold it? I'm in decent shape, tried it for the first time and made it just over a minute.

@rudysmustache for beginner do it for like 60 to 90 secs if you get better hold it for 2 to 4 minutes if you want to be even better try 5 minutes and up

you have to add to your regime as plank becomes too easy, just look around for some good excersices :) pallof press can be good, situps on a ball where u basicly lay on the ball, arch ur back all the way back so that it curves over the ball and then just lift ur body up till u crunch the top part of ur pack. I see many people trying to do situps/crunches and instead they just damage their neck and so on by holding hands behind, ball is a better option. U got many other options aswel, look around

Basically yeah, But you can't just cut off weight and gain a six pack, you need to work your whole upper torso, try weighlifting and pushups, sit-ups ect, and the plank will help too.

work your ams (deltoids)

surely that isn't obvious?

sounds like you need to add some more pushups into your routine :)
