Just got my cast removed for my boxers fracture?

ok so 3 days ago i got my cast removed. i had the cast for about a month. the doctor said it wasnt that bad of a fracture. so now that my hand is free the doctor is making me do these hand excersizes for two weeks to loosen up my joint.he said my hands pretty much healed already. i can make a fist now about 85% of the way down but it still feels pretty stiff.will i be able to move normally again?oh and the doctor said i will return in 2 months just to check out how my hand has been after recovery. ps, ima weight lifter so does this mean i cant lift weight until they see me again or can i start lifting again as soon as my joint loosens up??
