"Has anyone ever had any negative feedback?"
Patrick Sometimes someone will write in saying they did not get faster. We then review how to do the exercises with them to make sure they are doing them properly. Sometimes that helps.
Usually people who have negative feedback have never really tried the program properly themselves or don't understand it.
They may have the idea that the program is to help them get stronger and they think there are better ways to get stronger - which is understandable;
O r else they may teach other methods to get faster and don't want to introduce new techniques that would change what they have been teaching all along - that is to be expected.
Or they may have had some success getting faster using other methods and it makes them feel good to think they have the answers - that can happen too.
Drinking lots of water is commonly espoused in weight loss regimens and is regarded as healthy; however, few systematic studies address this notion. In 14 healthy, normal-weight subjects (seven men and seven women), we assessed the effect of drinking 500 ml of water on energy expenditure and substrate oxidation rates by using whole-room indirect calorimetry. The effect of water drinking on adipose tissue metabolism was assessed with the microdialysis technique. Drinking 500 ml of water increased metabolic rate by 30%. The increase occurred within 10 min and reached a maximum after 30-40 min. The total thermogenic response was about 100 kJ. About 40% of the thermogenic effect originated from warming the water from 22 to 37 C. In men, lipids mainly fueled the increase in metabolic rate. In contrast, in women carbohydrates were mainly used as the energy source. The increase in energy expenditure with water was diminished with systemic beta-adrenoreceptor blockade. Thus, drinking 2 liters of water per day would augment energy expenditure by approximately 400 kJ. Therefore, the thermogenic effect of water should be considered when estimating energy expenditure, particularly during weight loss programs.
If you are recruiting a person who needs or demands more money or better terms than you can offer, then deal with the matter properly before the candidate accepts the job - changing pay or terms after this is very much more difficult. If you encourage a person to accept pay and terms that are genuinely lower than they deserve, by giving a vague assurance of a review sometime in the future, then you are raising expectations for something that will be very difficult to deliver, and therefore storing up a big problem for the future.
