Tips for improving my position

[ChestnutConvert]

It was pointed out to me that i have been tipping my pelvis forward in the saddle, i can't say i've noticed but become paranoid over it now.
Does anyone have any tips for staying more upright or exercises to strneghten 'my core' etc...?

pilates or exercises using one of those giant swiss balls- you can get videos with a routine on them

a couple of private lessons with a good instructor?
