Check out this book- http://www.amazon.com/dp/1450419690/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=32UVQXU46FF9V&coliid=I36NTUAS8UY3E9

If you click the picture of the cover, you can scroll through the book and see exercises for free. It has a ton of core exercises you can try! Variations of the plank are helpful. Luckily you don’t need machines to work the core!
