What is the best way to get and keep a good looking body (male) at home without buying anything?

Bodyweight exercises are one option available to all: http://bit.ly/bc-bw. Another would be putting some weight in a backpack and going for a walk: http://bit.ly/bc-ruck (that site will sell you stuff to do it, but you probably already have things that would work). Or, because I’m really not an expert in human physiology, you could talk to someone who is. The BC Rec Center has personal trainers who can help you set up a program that works for you: http://bit.ly/bc-recpt
