Pool exercises

Hey guys, I have a small above ground pool that I use for exercise, because it is low impact on my joints. I do all kinds of exercises in there targeting different areas but I haven't found one for my stomach muscles... any suggestions?

Thanks

If it's not too deep, do knee lifts while standing up [hold your core muscles in while doing them]. If possible, do the bicycle / crunches by sort of floating on your back while hanging on the side of the pool. Also, if you have a floating noodle, do the crunches in a stand up position by not letting your feet touch the bottom and bringing you knees up in a bent position as if you were trying to jump. Have fun!

Those are excellent suggestions and I'll be able to do all of them! THANK YOU!!

I do aqua fit and we do the crunches with the noodle, by laying out straight on the noodle (it's under our armpits) and then lifting ourselves to a sitting position.
Another one we do is, laying on the noodle as before, bringing our knees up to our chest, then kicking them out straight to one side, then bring your knees up to your chest again and kick out to the other side. It works the sides of your stomach.
If you have foam weights (or I guess you could do it with a noodle), lay flat out on your stomach and push the weights/noodle to the bottom of the pool - a bit like push ups.
You can also do this one..... Stand straight up, slowly bring your knees up (it should look as if you are sitting in a straight backed chair), then slowly lower your legs - feet should be together throughout - this exercise needs to be really controlled and slow - you can use a noode behind you, to help with balance.
Another one that is similar tothe previous one, same movement - but.... Do it with your legs apart and straight (it should look like you are sitting in a straight backed chair, with your legs apart and straight). This one takes a lot of control.

I need to update ( been to aqua fit today)..... The exercise where you lay on the noodle, bring your knees to your chest and then kick out to one side, knees back up to your chest and then kick out at the other side. I forgot an excellent stomach extension of this (called a tuck through). Lay on your back, bring your knees up to your chest and propell your head and shoulders forward and your legs back (you should then be laying flat out on your stomach). You then bring your knees to your chest and kick forward, head and shoulders back (you should then be on your back).... You get a great pull onyour stomach. You can then alternate - kicking left, then right, then forward, then back. We do it about 30-40 times. Very tiring.
