You don't need heavy weights. Muscle growth has been observed in clinical settings with as little as 30% of your 1RM weight. Just keep repping until it burns like hell. It's much harder to get close to failure this way but if that's all you can do then that's all you can do.

You ever seen Olympic gymnasts? Bodyweight exercises can actually work, and you can get creative with stuff you can find around the house or in your garage; sandbags, water jugs, logs, a pullup bar, exercise bands, all can be used as a temporary substitute for a gym.
