It depends on the exercise program.

I'm currently doing a Texas-method-based lifting program: three-days, medium-light-heavy. The "medium day" is mostly volume with (e.g.) 5x5 squats at 90% for example; I'm zonked after. My light/recovery day I'm only doing 70-75%. The heavy/intensity day it's 1x5 100% (or trying to reach five reps).

Of course if you're going an HIIT program, then yes, you should probably fairly drained afterwards.
