Bullz-Eye.com Fitness Editor Mike Furci answers readers questions about water, U.S. hospitals and myths about salt.

…it?s not necessary to drink eight 8-ounce glasses of water a day to maintain optimum health? We?ve been told this arbitrary recommendation for years. There is little evidence for or against any of the supposed benefits of extra water, such as increased toxin excretion, improved skin tone, lessened hunger, and reduced headache frequency. A review of the available research concludes that for average healthy people, more water doesn?t mean better health. (Mercola.com newsletter)

In the case of weight training, the duration of exercise is the volume or number of sets performed. Intensity and duration have an inverse relationship. Meaning, the harder you train, the less time can be spent training. This is because we have a finite amount of fuel available to carry that level of stress. This is not a choice or an opinion; it?s fact.

This brings us to the most common way people train too much; too many sets. Although training hard is the best way to move forward, some people are under the impression that doing more is training harder. Performing anything more than what is optimum, will hinder your progress. Yet, most perform more sets with reduced weight or reduced intensity because of the more is better mentality. Do not get caught in this no win cycle.

Training all out, poses extreme demands on the body’s resources, which are governed by genetics and in limited supply. Because of this finite supply, the body will not allow you to train ?too hard? for too long, and gives clues you are reaching your limits. Once you reach failure performing a set, or run out of gas during a workout, you?re simply not able to train any harder. And because training intensity is the number one stimulus for building srength and muscle does it make sense to do more with less.
