just get under the weight (or over in the case of rows/deadlift) and find a 5 rep max (the most weight you can do for 5 reps) once you find this subtract about 10-15% of that and start there. just remember to start really low when finding the weights you should use, you dont want to get hurt before you get going. also remember to add atleast 5 pounds to the bar everyworkout untill you cant get the 3x5, after you get there we'll tell you what to do after that.
