Getting in shape for hockey?

so i have been out of hockey for about a year and i am looking for ways to get back into shape. There is snow all over the place so i cant skate around outside and jogging is out of the question as well bec of the snow. I have weights at home that I am gonna start lifting but what should I do to gain stamina if i cant skate. I cant afford to go to the gym so any ideas on what i should do to get into shape? would jump roping help stamina?
