I know, it is infuriating. I assume that they see the power lifter guys, who do high weight/low reps, and think that is how you lift for fitness. But of course, being fatties they half ass it. They would benefit far more from low weight and actually moving.  Having said that, it amuses me that they even think weights are what they need to be doing. They need to hit the treadmill/bikes/stepper and eat clean daily, for at least a year, before even touching a barbell.
