Best exercises for core strength?

Ahrena

That I can do at home?

I have 1.5kg weights, that it for equipment.

Basically I'm an aerialist and struggling with a couple of moves for a routine I'm doing in April. Increasing
My core strength is key, I have about 6 weeks (that's when the routine needs to be sorted).

What sort of things can I do at home, and how often, to increase my core strength as much as possible?

I have a decent amount of core strength; ride horses and pole dance/silks 3-4 times a week BUT I need to improve it to crack these moves!
