rograms like Rushfit, Insanity and P90X aim to offer a comprehensive program that will help consumers successfully reach their health, fitness and weight-loss goals. There is no question that these are ambitious goals, particularly when you consider how many variables are involved, such as diet, exercise (activity and non-exercise activity) and behavioral change. After all, these are the foundational principles for achieving that elusive physical metamorphosis so many desire, but they must never be offered at the expense of good science and safe programming appropriateness.
While each of these programs possesses both merits and drawbacks, it is important to consider the bigger picture. What happens after the immediate workout that leaves a person out of breath and lying flat on his or her back? Or after the short-term extreme diet that promotes unhealthy weight loss? How do these experiences change the way people think and feel about their health and well-being, and how will it influence their choices in the future? A program that leaves an experienced exerciser exhausted and elated at the notion that muscle soreness is merely a forthcoming adaptation means something completely different to an individual who has been told by his or her physician to get into shape.
To that end, we hope this evaluation provided greater insight into the strengths and weaknesses of these popular programs. If this review helps you serve the needs and desires of your clients and the public with whom you engage in fitness dialogue more effectively, then we have accomplished our primary goal with this endeavor.
