Hi Kerrianne91-
Congrats on getting thru that!!! Just go basic and easy to get some
core strength back.
Crunches
Twisting crunches
Go easy at first, work up to 25 of each. When you can do that without discomfort, increase to 2 sets of 25 of each exercise (work up to 25 on that 2nd set- it may not come immediately, but you WILL get there if you have a positive mindset) .
Once you can do that, add another exercise such as reverse crunches.
Just take it easy at first- work within your comfort level for a while before pushing yourself. Your strength will come back rapidly, so nuthin' to worry about!!!
Then just work from there- adding new exercises, or a few more sets. If you get stuck or need more advice, feel free to post back.
Oh yeah- welcome to DF.com!!!
