I've been lifting for about two months doing a ppl routine 6 days a week but I haven't been doing any an work. It says put your own in but I'm not sure what to do.

I did do planks for a couple of weeks doing 3 sets of 45 seconds but I know my abs are very weak. I was thinking of hanging leg raises and something else.

I'm just looking for a good beginner ab routine I can incorperate and how often should I be doing it would be helpful.
