Okies then..
You don't need anything but bodyweight to get a good workout. The military has been doing it for a couple of thousand years, but you can also use tools around the house.
Pushups - vary the angles
Squats/Knee Bends
Lunges
Chins
Plyometrics - jumping, bounding, leaping, etc.(according to some, plyos can induce hypertrophy to a degree)
What about a chinup bar that screws into the wall? They arent that expensive, maybe 15$. A medicine ball and/or a stability ball would make some good additions. Even without these things, there is plenty to do.
You could also take gallon milk jugs, and fill them with water(water weighs 8lbs a gallon). Do walking lunges, stand on the edge of the stairs while doing calf raises, even overhead presses with them. Sand is heavier, and you could even fill them with that. Get creative
