Even the arguments of not having time or having to do low-impact exercise don't hold up. I purchased this elliptical ($200) and paid a college kid $20 to build it. There's even cheaper ones than that on Amazon, down to a bit less than $100. I got myself up to the point where I could walk for an hour while watching TV, then began increasing the weights. 2.5 years later, I'm on a 5/8 with its weights and can go for 90 minutes.  None of these fat fucks have a legitimate excuse.
