Telling them to take a deep breath in could also work - just have to make sure that their expression is still good.

I don't really care if someone tells me to suck it in (as long as they're not rude about it. ex. Suck in your gut) - I normally do anyways so I don't need to be told.

Agreed.  Although I don't get offended when photographers ask me to "suck in my tummy," I think it's always best to direct with positive rather than negative language.  Another example could be saying, "lift your chin," rather than, "don't look down!!"  When photographers give positive directions rather than telling me what they don't like, the whole mood of the shoot becomes more collaborative and less stressful.  Also, I don't particularly like cute or childish language like "tummy," especially if I'm naked and trying to look regal or sexy.  If you want to make a model feel like a sexy, empowered woman, treat her like one.

Leave out the tummy.  Just say "Suck it in for a moment." [click] "yeah, awesome, thank you.!"

If they get hurt, I suspect then that perhaps they are a bit delusional or playfully giving you a hard time.

If you have to say anything beyond gentle coaching you have:

A) Casted the wrong model

B) Casted an amateur model who doesn't have a good idea of her body and posing

Here is the thing though...are you certain it's the model and not you...asking her into positions that make her look big or sloppy?

..the same way you ask for no cheese on the hamberger

for beginning models, showing the difference on camera also works wonders. Often they don't know yet how much a difference a little change in posture can mean. So show them a shot where they were a bit slouchy and not sucking it in, and then show them a shot where they elongate their body and let the tummy stick out a bit, and the difference between the 2 shots will be very motivating . After that just say "remember the tummy" everyone once in a while, or "tummy!" or "stand up straight!"

This works for me, makes me laugh a little, humour always makes a shoot easier anyway.

I'm just honest with it. I usually say "Come on...suck that belly up, poke the girls out!"

Sometimes I say "Tits up!" (only if I really know you!)

I use, "tighen your core". It's not just about sucking in. Most models with good abs want to show it off and tightening it shows the definition better.

I always tell the ladies, if you're shooting swimsuit and after the shoot you don't feel like you just had an ab workout, you're not doing it right.

Me too. I sometimes do it subtly by asking the model to arch her back or put her hands behind her head or something 'as it's flattering to your tummy' - once a model knows you're working with them to show them in the best way - they are usually well on board.

Book models that do not have one?  If it's so important to you, book the 'right' model.

Beyond that, just say 'can you draw your tummy in a bit please?'
