Why am I getting nauseous when I'm weightlifting?

It's been about three months since I worked out regularly. I find that lifting for strength (i.e. 80% of max for 5-8 reps) causes me to feel nauseated about 3/4 through the workout sometimes, so that I can't bring myself to finish. I took a weight training course last semester and was affected the same way every once in a while. I warm up, stretch before and after, breath when I lift, drink plenty of water, take care not to eat 1 hour before working out, skip a day between workouts, don't lift more than I can handle (I reduced the weight from what I ended on in the class to a seemingly suitable weight. I got a 98 in the class incidentally). What's going on?


Are there any nutritional benefits to swallowing semen?

1) I'm worried. What happens if you eat your own sperm?

2) Today a girlfriend and I were discussing the nutritional value of sperm. While performing oral sex, if you swallow, I was told that it is very high in protein. However, I was also informed that it is very high in calories. This may seem like a weird question, but I would like to know what nutritional benefits are involved when "swallowing" and how many approximate calories are in a man's ejaculation? Thank you for your help in this matter.


Why isn't my weightlifting resulting in muscle definition?

I am a 22-year-old male who began weight lifting two years ago to get into shape. The problem is I'm still not in shape. I can lift huge amounts of weight, but instead of having a chiseled body, I still look like a fat guy. I mean, I'm big and strong, but I look like I was sculpted from lard (I'm 5'11 and 215 pounds). I do roughly 30 minutes of aerobic activity and about 90 minutes on the weights. Should I change my activity and diet to get leaner?


What are the symptoms of a heart attack?

1) I've heard that the symptoms for heart attack differ for men and women. Could you please send me info on these differences? Also could you give me some possible diagnosis for a feeling of heaviness in the chest?

2) Is it possible to have a heart attack without knowing you're having a heart attack?


Is stress causing my chest pain?

1) For the past year now, I have been getting sharp chest pains. Sometimes it feels like I am about to have a heart attack. I find it painful to breathe for the couple of seconds that it happens. The sharp pains occur mostly in the lung/heart area. However, I have also felt them in the lower chest area as well. I don't know what is causing this.

Also, it occurs most frequently during the school year. I should also note that during the school year, I tend to eat greasy fatty foods. However, I had my cholesterol level checked (95) which is low. These pains come any time of day, while I am sleeping, walking, sitting, etc. I am 21-year-old female, if that helps.

By the way, I have a doctor's appointment back home later this month. But I want to have an idea why this happening. Others mentioned to me things about stress, something about a dog's heart, and I was even thinking that it might be cancer.

2) I've recently been experiencing chest pains in the sternum area. Although I don't believe it is related to heart trouble, I think the pain is originating from the bones or muscles attached to the sternum. I have seen doctors but most are clueless as to where the pain may be specifically originating. An interesting side is that during times of stress, the pain is more severe and concentrated at specific points along the sternum. One hypothesis is that the pain may be related to an injured sterno-manubrial joint. If indeed this is the case, what therapy is available to a poor, uninsured student? My mental health is being affected since my once pumped-up, rock hard body is slowly atrophying since I can't lift weights without extreme pain. I'm depressed because the size of my chest is now smaller. What do I do? What's wrong with me?


Is it harmful to sleep on my side?

Is sleeping on our left side in any way harmful for the heart (or anything else)? Some people tell me we shouldn't do it and others tell me it's actually better than sleeping on our right side. What's the truth?

Thanks!


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.
