This is confusing. It seems like somehting a good rationalist should not have any problem with. And you're supposedly the greatest rationalist around. Are you sure you've actually applied your rationality skills and done stuff like sat down for 5 minutes (each) and thought about questions like "What exactly am I trying to accomplish with exercise, and is there any other way to accomplish it", "How can I find out what kinds of exercise will give results" , "can I replicate what a fitness trainer does myself, find the information online, or find someone willing to act as one for free?", etc.

There are probably a decent number of people with medical knowledge here, who knows these things. Heck, if a few things (like living on the wrong continent) were different I could've just given you my athlete sisters number.

Edit: Also, why is everyone talking about expensive equipment? I'm pretty sure you only need equipment for advanced training if you want to compete or because it's easier/more comfortable, general fitness and health I can see no reason to do anything other than running and stretching and push-ups and such. I'm also pretty sure you can use normal stuff lieing around even for the things you need props for. I'm no expert thou.

... goodness I can't believe I just typed this. -_- Feels like heresy telling Eliezer what to do, especially in an area I consider myself to know nothing about. I'm fully prepared for this to be down-voted to oblivion.
