Weight loss and fitness boot camps can give people who are serious about losing weight the opportunity to try a different approach. Accountability and motivation are two key elements that keep people moving forward, and many resorts and spas have started to add "boot camp" style programs to their list of offerings. A few stand out from the crowd in terms of popularity and results. Boot camps range in intensity from mild to extreme. Although the mentality of a boot camp environment isn't for everyone, the strictness of the routine can sometimes be motivation enough for some to push beyond their norm.
