Weights and dryland weekly workouts?

I am swimming 3 days a week around 3000-4000 yards each day for 1 hour. The days I do not swim, I run 3-4 miles. I would like to go back to do some weights/dryland workouts. I am 49-year old male ; 5’7” ; ~150 lbs Is there any place where I can find some weights training plan? I was thinking to start doing something the same days I swim (Mo, Wed, Fri). I swim at 6am, so I was thinking to do the weights at noon/afternoon Any hint/thoughts/workouts/links will be appreciated Thanks Bernardo
