Why do I get super sleepy after a lengthy workout at the gym?

I am a workout junkie, and the same thing happens to me.  Basically, your body has lost potassium, along with other minerals, and you have also worked muscles that now need to rest.  As they start contracting, your body starts to feel the effects of it.  \n\nMight I suggest eating more bananas and other foods with potassium, along with drinking Gatorade Fitness water.  But, also realize, your body does need to rest from a hard workout, and as your metabolism has been increased, it is burning more energy faster, which can cause the body to feel fatigued.

it could be muscle soreness, but this usualy occurs the following day.\n\nthe most likely factor is that you are not following proper form doing your exercises. this is generally 90% of the problem especialy if your back and neck is involved.\n\nif you go to a gym where there are trainers, i would suggest you take a quick course on proper exercise form, it will save you a lot of pain and will help you build muscle faster. dont feel bad, all newcomers at this make the same mistakes.\n\nto help in your problem, you can also apply ice for no more than 30 min to the area that hurts, it will help stop the swelling. after that apply something hot for another 30 min, this will cause increased bloodflow and will help repair the muscles that are in pain.\n\ngood luck!

i had that problem, but without the redness.  I worked out at the gym allot and lifted heavy weights.  I thought it was some kinda virus i picked up from sharing equipment.  It turns out its some kinda skin condition, an allergy kinda.  It went away in time... you should get it looked at by a doctor immediately because the redness does sound a little peculiar.

Be sure you are using a good mulitivitamin to help boost your energy levels.  Also you may want to try drinking a product that will help replace your electrolytes after such a work out.

I find working out and drinking lots of water seriously helps you have energy...it may not seem like it because working out wears you out, but your body gets energized from working out...so jog or do aerobics the night before. You will feel great the next day I promise.

I had that problem once and it was my caffine intake. I was drinking so much soda that it made me tired in that way. Not sure what your habits are but try drinking water. Its incredible how great it makes you feel if you drink enough. Try water for a week or so.

Well if you are on any drugs right now that could be affecting you!  I know I was on a drug and it made me so incredibly tired!  I am now off that drug and I am great!  If this isn't the case perhaps you need to try energy drinks or see if you are getting enough iron!  Iron is very important and a lot of women are lacking in this department!  Try eating some foods high in iron like broccoli and nuts!  Good luck!  I know how horrible it is to be tired!  Also try planning things to get you excited!

Not sure exactly what, and there may well be a link: you might have strained a muscle: it's usu recommended you warm up before you start: stamina/endurance /general training.\nI'd assume your posture has something to do with it.\nRalgex-or something of that ilk-is pretty good in the meantime, plus plenty of rest.

both the headaches and lack of energy during training can be a result of not eating or drinking anything prior to the workout.\n\n30min to an hour before..you should give your self a little snack to give you energy for a workout.  (piece of a fruit, orange juice)

It depends a lot on if you eat anything after your work out.  Right after your workout, make sure to drink a protein shake (or eat something high in protein) and some food with simple sugar (banana, 1 can of regular soda).  The protein will help you build muscle and the sugar is to raise your insulin levels to help carry the protein to your muscle.  \n\nIf you're not eating right after your workout, then yes you are wasting it because your body is starved and needs nutrients to recover.

It's because when you're still for too long your circulation(blood flow through body) slows way down and doesn't get all through your extremities (arms and legs) properly.  That's what makes you feel kinda tingly. That's your body's way of telling you it's had enough of the computer chair and would like to go to bed.  Or get up and do some aerobics!

The first possibility is that you are overdoing it. You must allow at least a day of recovery between very intense workouts. If your muscles are sore,  as opposed to tired, then the workout may be too intense.\n\nThe second possibility is that you are using too heavy a weight. Some people do better with few (<10) reps with a very heavy weight, and 3 sets of this, while others do better with many reps (about 25) of a light weight, and 3 sets. It depends on your body.\n\nThe third possibility is that you may be doing the wrong exercise that is optimum for you. You can work biceps by lifting a weight, pulling a cable, or using an elliptic (Nautilus) machine. Each feels different, and works the muscle differently. You may respond better to one than the other.\n\nA final possibility is that you are not getting enough protein, but this is unlikely unless you are on a strange diet.

dude, i'm happy to help, but you have to take your picture off your little square. seriously.\nanyways, this is normal, your muscles are getting used to the stress you've put on them. you will probablly feel sore if you go really hard one day, but if you continue to work out everyday, it is normal, and GOOD not to feel sore after every workout.\nkeep it up!

Have you been working out or walking a lot more. It could be that you have strained your muscles or something. If it lasts to long call the doc.

'The blood rush after climax depletes the muscles of energy-producing glycogen, leaving men feeling physically drained. \n\n'Because they have more muscle mass than women, men become tired after sex and this subsequently leads to them feeling sleepy.'

Some people just have a sleepy reaction after swimming, probably a combination of the warm pool air, being "weightless" for so long, and the chlorine fumes.  Also, it is easy to overheat in the pool because your sweat doesn't evaporate like it does on the bike and on the run, and you use more calories.  I'd suggest brinking a good quality sports drink to the pool with you to replenish liquids and carbs during your workout, and also, you want to make sure you put a small amount of carbs/protein in your body within 30 minutes of your workout to help with recovery (chocolate milk, wheat crackers and peanut butter, half a turkey sandwich, etc.).  Sounds like you are training for triathlons, maybe?  The carbs are a good idea in races too after a swim, but you need something easily digestible, which is why some athletes wrap a powerbar around their handlebars.\nEdit: Also, since it sounds like swimming isn't your strength, you may not be getting the adrenaline rush after it like you do with running and biking because you are swimming at a long slow pace.  You could try an interval workout to switch things up and get your heart rate up a little higher.  You can find some good workouts here.  http://www.swiminfo.com/swim-cgi/
