I'm already at a great weight (101 pounds) and very happy with my body.
I could certainly stand to tone my muscle up a bit but I'm very comfortable in a bikini :P
I have a long distance boyfriend coming into town tonight and I'm a little bloated today :/
I noticed that when I go to the gym I leave feeling a little bit tighter and look a little bit slimmer.
I was wondering if there was a way to tighten up temporarily for tonight.
I heard cold showers or ice packs work but it sounds kind of fishy lol.
So I guess I'm going to do some basic ab and leg workouts and then take a cold shower after and see how that works.
If you have any input or experienced answers that would be awesome!
I'm not looking for some crash diet to lose weight, just a little trick to tighten up fast.
Thanks in advance for your answers!

I'm telling you! do this it works!
squat rows (squat and lift dumbells up to your chest)
tricep curls
bicep curls
regular squats
running
decline crunches
bicycle crunches
I swear by it! do these exerdises everyday and you'll look like daisy duke!
(you said just a flat stomach, but this also works wonders on your legs and arms!)
