How can I measure my heart rate and exercise intensity?

1) I work out on my treadmill 20 to 30 minutes a day, usually one to two miles. My husband says that there is a minimum and maximum heart rate. Is there a formula that I can use to calculate this information? Please advise.

2) Is there an equation that would relate the relationship between exercise and heart rate. I understand the maximum and minimum heart rate equations for exercising. I would like to know if someone who is at their max. heart rate would be able to predict their heart rate if they increased their intensity. I am looking for something relating work intensity to heart rate.


Is soreness an indicator of a good workout?

My trainer is getting annoyed because I am not experiencing soreness. I have been working out now with him and other trainers, three times a week, for three months now. Plus I do 45 minutes of cardio four times a week.

I think it's kind of odd that he bases his progress on how sore his clients are. I was always led to believe that soreness in muscles comes from working newfound muscle groups or aggressive workouts. During our workout I am feeling my muscles being worked and I have lost a number of inches and lbs since I have been working out. It seems to be a large issue with some of the trainers at this gym. I am wondering why! Also he had me doing 420 lbs on my legs. I am not a body builder nor do I want to be. I started to tone up. Advise please!


How do I prevent and reduce muscle soreness?

1) My husband is in an intensive training program to become a firefighter. He trains Monday – Friday. As a consequence, he is sore everyday. I know the best remedy for sore muscles is rest… but he doesn't get any. Is there anything else he can do?

2) I am an avid weightlifter. I want to know how to prevent muscle soreness, or flush out the lactic acid from my system. Thank you.


Why does eating sugar make me sweat?

I have noticed that whenever I eat certain sugary foods — especially chocolates and hard candies — I break out into a cold sweat and feel extremely uncomfortable for about half an hour. I have no problem, however, with pure cane sugar (when I drink coffee or tea, for example). Is this a normal adrenaline reaction to sugar, or a certain type of sugar?


Should I smash my cyst with a hammer?

A couple of months ago I developed a hard, bony growth on my instep. I noticed that the top of my foot was hurting, and when I took my shoe off, there was a red lump the size of a quarter (it's not red all the time, just from rubbing against the shoe). A friend of mine who is a nurse said that it's probably a ganglion cyst and the best thing to do would be to, and I quote, "hit it with something really hard," like a dictionary, or a hammer. It should break up immediately, she told me. She hasn't seen it, by the way — this was over the phone.

I'm surprised that she thinks it's a cyst, because it's awfully hard — I would have just thought that it was a bone spur. What do you think? And is smacking a cyst with a dictionary really the way to go?
