Oh, here's the forum!
I couldn't find it for the last two days.
Good one, Swantje! Tips from my knung fu instructor:
a) you'll ache more 48 hours after excercise than 24 hours, so have a day off inbetween gym visits: don't overdo it.
b) Fresh orange juice is good for muscle aches.
I really like exercise now I'm used to it; I feel really good afterwards.
