Push Up & Crunch issues

This may seem a really stupid post but I just havesome simple questions.

lately when I have been pushing myself on the push up front and crunches, but i find myself waking up the next day with real tight triceps and arm pits and with the crunches a really sore stomach with the effects lasting 3-4 days. stopping me doing a lot of other exercise.... Now would most on here say its just whats ment to happen? or doing to much or just incorrectly? atsch

 

Lactic acid op

 

Sounds like someone's just started training after a loooong lay off.....

 

Try morphine.

 

DOMs. Basically your body saying "holy ****, I'm not used to this!".

Carry on.

 

Cheers fellas pretty much what I gathered but you never know
