Sometimes I get really shaky and feel very weak. This happens a lot of times after, or during cardio exercise. Does anybody know why?

    could be low blood sugar... try having a snack to see if that helps :-)

    It could be low blood sugar. What about your iron levels?

    Sounds like low blood sugar. Try to eat a little something before a workout and make sure you're hydrated.

    If it happens a lot, you might go check with your doctor just to be safe.

    I used to get this before I was diagnosed with high blood pressure, go and see your doctor and get it checked.

    Mind you, it could something simple like not eating enough.

    Low blood sugar. You may not be eating enough.

    I feel that way when i'm dehydrated. Do you take blood pressure medicine or anything like that? Those combined with weight loss may be lowering your blood pressure a bit too low.

    be careful, I felt like that too and after giving blood last week I actually fainted and fell breaking a bone in my wrist. I was also a bit under my calorie count each day.

    I used to get that a lot and still do just not daily or too often. You need to eat more or hydrate better. When this happens, drink some water and eat a good snack. Make sure your calories are not too low.

    Eat more protein not very heavy food before exercising like pb on a slice of toast, boiled egg. try to eat at least 2 hours b4 a workout. YOu are working out too hard and not enough energy or low iron. That's what happened to me it was iron so i had to make sure I inculcate enough so when I do workout I don't faint or get dizzy.

    This happens to me sometimes too, I also believe its just a dip in your blood sugar. The go to quick fix is a glass of orange juice or maybe a protein bar that has some sugar in it. It'll have you back to normal in just a few minutes.=) But if it happens very frequently or gets worse I would discuss it with your doctor at your next doctors appt.

    Based On your diary you're eating enough most days, are you eating anything before your workouts? And how long are your workouts? If you have some carbs before your workout and you're under an hour I'd check with your doctor, blood sugar issues along with blood pressure issues could cause big problems for you undiagnosed. I did notice some processed foods in your diary like poptarts, things like that are super easy for your body to digest and can cause instant spikes and then drops in your blood sugar which could lead to that shaky light headed feeling. I have issues with it and make sure I eat mostly whole foods and fruits vs juices and pastries which helps a lot!

    I have issues with low blood pressure. On a good day, I can hit 105-110 over 60 -ish, and I find that when my blood pressure is lower than that, I have the same issues. Have you had your b/p checked??

    It sounds like low blood sugar. Try eating something 15-30 minutes before working out and try a protein shake immediately after exercise. If this doesn't help, you should see a doctor.

    It is worth getting it checked out by the doc. Check your'e eating enough too. I had the same thing and it was a combination of not eating healthily or enough to sustain the exercise and my blood pressure being high. Also helped to drink more water!

    I found that as long as I eat a snack before my workout (like a hard boiled egg) and drink water during, I don't feel that way anymore :)
    If you try that and it is still happening, seeing a doctor would probably be a good idea.
    Good luck.

    Are you logging and eating your workout calories? Sometimes you just need to eat them back when your feeling weak.

    My blood pressure is normal, so my faint was put down to not eating enough with giving blood, but it would be worth getting checked out.

    I don't see any exercise logged in your diary, and you are consistently below your calories (and your diet seems to have a lot of excellent components, but is a bit sugar-heavy). You mentioned that it's "after cardio", so you're obviously working out.

    If you're always under on your calories AND you're working out and not logging it, you're probably hungry. I'd eat some more fats and proteins if I were you. Feed the machine!

    Also, I know your snacks are good, but I'd recommend something less sugary and more fatty/protein-y. They'll make you feel more satisfied and feed more of what your body really, honestly needs.

    If eating more doesn't help, see a doctor. There could be something else wrong. But based on your diary, low blood sugar/hunger is probably a really good possibility.

    I felt like I was going to die when I first got started.. it'll get easier. Worth a doctor visit but it may just be that you're stressing your body in a way it's not used to.

    I get a similar thing sometimes!! I find it is a little better when I drink lots of water but more than anything if I really concentrate on my breathing I feel better! Maybe you are not getting enough oxygen while you are working out? Just a random idea!

    It's most likely due to a low blood sugar. I was on a very low carb diet last summer, eating mostly only veggies and lean meat and I would often feel like that after working out and sometimes without exercise. When I felt all weird and shaky, I would eat some berries (raspberries or blackberries) because they were lower in carbs than most fruit, and I would feel so much better! I know you're not an low carb diet but I felt exactly the way you described, and I pretty much guarantee incorporating more sugar (the good sugar in fruits) will fix the problem.

    Also make sure your hydrating! It's such an important factor! I have low blood pressure, that combined with a slow heart rate and being taller (5'7'') if i get up too fast I can get really dizzy, sometimes everything will go black, and I've actually fainted a couple times. Drinking more water made such a big difference, especially a glass right when I wake up. Almost a 1/3 of what you exhale is water, so when you sleep at night you're losing a lot of water! Dehydration can definitely be cause of those symptoms as well.

    I get like that too, and know it isn't blood sugar since I have a pre workout snack. What I noticed is that when I am not focused on my breathing it happens. I really started concentrating on that and it's gotten tons better! That being said I did look at your food and I would recommend increasing your calories, increasing protein, and lowering your sugar intake! Good luck and I do think it gets easier.

    When I was eating the recommended 1200 MFP calories I was getting that all the time. Now that I have upped my calories to my TDEE mi us 15 % and never go below my BMR it hasnt happened since. It feels so great to be satisfied and feel great when working out.
