What do you mean by “seeing results”? If you mean building muscle/gaining definition, then 3 times a week might be slower than lifting more often a week, but the largest obstacle is going to be nutrition/rest, regardless of workout frequency. If you mean improving your lifts by following a program and overall mental/physical health benefits, 3 times a week is plenty and a great start.
