Iron Man Gym

I used to go to a gym, but I had to cancel my membership recently. I want to continue to work on. I am 17 and about 145. I have one of those things fitness iron man, its basically a strange pull up bar and a dumbbell of up to 35 lbs that I can do a lot of repetition because it is. I was wondering if anyone knows a good plan that I can use that uses only two things besides sit ups and pull ups. I'm looking to get big.

Well, I do push ups and crunches, they work with middle and upper body and you can run to improve the problems of weight and lower body muscles
