While these folks were at the gym though, my bet is that they work hard. Possibly harder than they should have worked. That is strike one. Doing to much to soon can destroy long term motivation and it can result in injury. Strike two, a abrupt change in lifestyle and and logistics shocks the system. Strike three may be the idea that we need to see progress immediately.
Patience is key and people new to exerciser or working out would probably do better to place more emphasis on process goals as opposed to outcome goals. What we want to avoid is exactly what seems to happen, our well intentioned folks head back to the bench (or couch) not having realized anything but frustration.
