I only workout 4 times a week (M,T,Th,F) in the mornings. Wednesday and Sunday are recovery days. Saturday is yard work. I do some treadmill running just before (20 minutes on lower body days and 30 minutes on upper body days), after which about 1 hour of weights. In the morning, the gym is relatively empty, so I don't wait around. I often interweave exercises (not quite circuit training) so I don't need much rest time in between sets.

Depends on what I'm trying to get accomplished and/or if it's a two-fer day for me. For example, I lifted at 3 this morning (legs, a little small group work) and that took 1 1/2. I'll go back tonight for 30-40 minutes to knock out cardio, which I like to keep short and intense, and finish up any small group items I may feel I missed. On Thursdays I only ever work out in the morning. I'm scheduled to do chest, so that will take around an hour.

Anywhere from 20 minutes to 4 hours, depending on my level of stupidity. At zero stupidity, I keep it at an intense 20 to 30 minutes. At maximum stupidity, I do an intense 4 hours, and then get sick.

I train around 45mins 3days/week

During the school semester about an hour. Now I'm able to do 1.5 to 2 hours max. Depends if doing longer cardio also. I don't workout 7 days a week. At least not full workouts. Typically 5 days of real workout and anything else would be more of active rest type days.

It is usually three days a week weights for about 20 minutes (4 exercises, 15 reps each, 3 circuits - alternating musle groups and no rest time) then my version of hot yoga for about 15 minutes. Last week was to stressful so tomorrow is first day back. I try to do a lot of walking and stretching on my off days.

Usually around 80 minutes.

With all my old man, falling apart joints rehab and warm up before I can even touch a weight and the fat-burning afterwards... too long!

Never, ever more than an hour and usually 20-30 minutes not counting the five minutes of warm up. I belong to a CrossFit-like gym, so that's plenty.
