training abs with a single dumbell

[yeayead]

I got a 30 pound dumbell, no spare change and I want a six pack

What should I do? I tried doing bicycles holding it up behind my head a bit but it felt really awkward

If anyone could help me out here I would seriously appreciate it

thanks a ton guys.

p.s.
I know I know you need to have low fat to see abs
I want to bulk the abs

If you hold it high up on your chest you can do crunches with it. That works pretty good.

This ^^^^ and also if you have somewhere you can hang from you can put the weight between your feet and do leg raises or knee raises.
