feeling weird shaky and weak

Sunsh1ne

There are a variety of possibilities, from dehydration, low blood sugar as many have mentioned, blood pressure issues,and many more. I'd say check in with your doctor to rule out any of the more serious ones. If it's dehydration, remember that you should be drinking nearly a liter per hour during sweaty cardio. And if it's low blood sugar, get a sports drink that you like and mix 16 oz of that with an equal amount of water for an hour-long workout.

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

Bingo. Eat a banana after your workout or something light but sugary.

TAKE A VITAMIN D TEST FROM YOUR MD!!!!!!!!! trust me when i say if you have low vitamin d it can make you feel totally out of it(weak, shakey, cloudy vision, etc) !!!!!!!!!!! and if it comes back low make sure you get a prescribed vitamin d (NOT OVER COUNTER)

low blood sugar, are you eating breakfast? Also, just take a snack for the gym, a protein bar, pistachios a banana.

Blood pressure, low blood sugar, thyroid...could be anything. See a doctor!

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

It's likely one of two things:

1. low blood sugar - especially if working out fasted; or
2. need some sodium (I always put a teaspoon of salt and potassium chloride in a jug of water that I drink during any intense exercise periods). This is especially important if you're eating low carb (ketogenic).

This happens to me often and for me it is low blood sugar. I feel weak, shake, hot and then cold sweats, my heart starts beating weird, I get blurred vision and I get dizzy. I cant function properly when this happens, I have to sit and I eat and eat and eat until I feel better. The slower I eat and the calmer I stay makes the feeling go away faster. I eat high protein foods along with something sugary. Just to help keel the balance. That being said, you should probably see a doctor.

get to your doctor. You know how every exercise machine says to check with your doctor? and not to use if you feel shaky? yeah. they mean it. go see your doctor. Might be nothing, might be something, best to find out for sure.

I felt like that when I had my calorie goals set too low, like you seem to. I raised it to 1500, plus exercise calories, and felt 100% better (also lost more weight, inches, and had more productive workouts). Eat more.

edit: old post. OP hasn't been around in a while. Oh well.
