need ideas on building muscle at home....

i am looking for some ideas of things i can do at home to build muscle.    i know i can do push-ups and sit-ups , but after some time, that gets boring.

what are some things you do at home?

Maybe get some DVDs and free weights or resistance bands?

I love P90X--been doing it for a year now.  If you are just starting out, try Power90--it is the beginner version to master before P90X......they are available at beachbody.com

OMG, try to get some workout bands. They normally come in a box with 4 to 6 different resistances/colors and run around $10. They can be easily found at places like Walmart or sporting good stores. I never thought they were really very good for much until my physical therapist for my bad knees had me start using them recently. Boy was I surprised at how much you can do with them...and how much they actually make you work! lol
