Ab Excercises?

Hey,

I'm up to day 2 of the beginner cycle and I'm not sure what to do for abs? I don't have the strength to do hanging leg raises so I was thinking of doing Rollouts, however I'm not sure of how to do this at "75%". If anyone can give me a hand I'd appreciate it. :)

I should note I'm following the beginner program in the app.

You can do the roll-outs and record a fraction of your body weight. Whatever weight you use will be remembered for the next time. If you move on to another variation of roll-outs, say without your knees touching, you can increase the fraction you record.
