You may be able to get some dumb bells on line dante.
I only have 25 lb and use them for high rep shoulder presses and curls.
To be honest, the last thing you want to do is injure yourself at home with heavy weights and not be able to get medical attention. I have to really watch my lower back. A gym is a much more controlled environement and a lot of machines are very isolated to one specific muscle. I miss the gym big time. If i could hit the gym 3 or 4 days a week for only a half hour, this lock down would be a walk in the park.
