Do whitening toothpastes work?

So far I have been extremely impressed by your service. I trust you with a question which I know many people share: Are whitening toothpastes detrimental to the longevity of one's teeth?


What is proper gym etiquette?

1) When you are at the gym exercising do you need to wipe down each machine that you use even if you are not sweating?

2) I'm looking for some helpful pointers you might have on the subject of health club etiquette (i.e., don't wear perfume because others will leave workout equipment wearing your perfume). I would appreciate anything you have to offer on the subject.


Is weightlifting for 5 hours per day too much?

I am a wrestler and have very great ambitions within the sport. I lift weights for five to six hours a day, making sure I perform every set to failure often including negatives as well. In addition to working each muscle group two times a week, I make sure to give each muscle group 48 to 72 hours of rest. Recently though, I have learned that training longer than an hour a day can have a catabolic (muscle breakdown) effect on your body. This was very concerning to me because muscle-wasting during my training seems truly counter-productive, but I am also aware that a decrease in training may lead to muscle atrophy and that also poses a deep concern. I have also learned that cardio and even sleep can have a catabolic effect. I will have to cut my training time eventually due to time restrictions during the season because of school day and team practices, including traveling time and homework. I am posing a couple of questions within this letter: 1) Can I reduce the volume of my routine to about an hour and still make gains that are comparable or better to those I experience with my five to six hour workouts and if so, how? 2) Is catabolism truly a legitimate matter to be concerned with?


How will taking Clenbuteral help or hurt my bodybuilding journey?

My question is this, How much do you know about what the asthma medication called Clenbuteral does to a normal healthy male in regards to body building? What are the adverse effects? And I don't need to be preached to about why I should take it or not. I just want the basic gist of what it does. Can you answer this? By the way this drug is not used in the US for any reason.


Are there risks involved in hot yoga?

Hot yoga is becoming more popular every day but there is a lot of conflicting information regarding benefits versus injuries. Most of the information does not quote sources and is therefore is difficult to follow up on. It has unquestionably helped me become a more flexible person but there is a lot of information on the net regarding horrific injuries including slipped discs, muscle tears, neck injuries, emotional problems, and even strokes. Is there a research-based, or at least a factual breakdown on the health benefits of stretching at temperatures above body temperature versus the injury risk of exercising at temperatures above body temperature?
