biggest loser

I have a love/hate relationship with the biggest loser. I love it because it's inspirational and it shows how hard people work to lose weight and to reach goals that they set. It does get people off the couch and into gyms anytime it is on and it gets businesses,gyms or otherwise to hold their own competition among members or employees. I also love it for its entertainment value. I know there's always one contestant I'm rooting for or one contestant that I know will look great at the end. My favorite episode is always the makeover episode just because its such a huge change for them. You do get sucked in.
That's why it has lasted so long.
I hate it because it shows ridiculous weight loss that's just unattainable by someone in the real world. These contestants work out 7 hours a day. On the ranch that's their full time job. Nothing else. 1-2 lbs a week is attainable and safe.
I also hate it because many of the exercises the "trainers" give to the clients are unsafe. Take the leg extensions alone. It's a bad exercise for the knees based on pure physics but then throw in Bob pressing down on it to "push" the person to the limit. That is just asking to blow out someones knee. It's high school physics. I know they don't and can't show everything but at least show safer exercises and exercises where form is somewhat emphasized.

In the end it is a great show and I love watching it but its hard not to pick out things that worry me or disappoint me.
