Shaky and Sick After Cardio?

JurassicKitten

Hi, I'm a bit shy of posting on the forum like this, but I'm just wondering if anybody knows why I might feel so shaky and sick every time I do a cardio workout of just 20-25 minutes. I feel like I'm in high school gym class again :P I eat really well, make sure to make up for the calories I am burning, and I usually do the "modified" versions of the moves since I am just getting back into this. Thanks in advance!

What kind of cardio are you doing, and how intense?

Do you warm up properly and ramp up to the harder intensity?

Do you do cardio on an empty stomach or with a bit of food in your system? Do you stay hydrated before, during and after your workout?

Do you have any medical condition(s) that may come into play here?

I was just reading last night that in the higher heart rate exercises like elliptical that you are able to burn more glucose - well at least more than the percentage of fats. Maybe up your carbs or slow release carb types. Hope you find your balance on this!

I do moderate intensity cardio videos (Jillian Michaels and all that) on the modified side for beginners. She definitely pays attention to warm ups and cool downs so that's pretty good. I am very hydrated, lots of water and electrolytes before, during and after workout. I always make sure I haven't just eaten but never workout without having a proper dinner first. I don't have any medical conditions, but I do have problems with my joints, so maybe it's harder for me to move? As for the carbs, what do you mean by slow release carbs? I'm still getting used to all of this and I'm not really sure about all of that stuff yet ^.^

Thanks so much for replying! I really appreciate it ^.^

You are exercising out of your fitness range/level.

That is probably literally all there is to it :P I guess I just have to keep going and eventually I will get used to it and be in better shape No more shakiness and feeling sick after cardio is a great fitness goal! LOL

Yep. I used to get nauseous and throw up after 5-10 minutes of the 30day shred actually. Work your way up there, you can do it!

have you been checked for diabetes?

I feel like that if I don't eat enough before working out. It's lagging energy. I try and go workout no more than a couple hours after eating something substantial, like a meal. Not a snack.

Are you monitoring your heart rate as you work out? I always aim to stay around 135 bpm during my workouts. I'm 25 and thats the fat burning target for me. Talk to the trainers at the gym to find your heart rate so that you don't over exert yourself. You may find it takes less effort than you thought to hit it. Hope this helps. Don't give up

I would see a doctor.. I could understand if you are extremely overweight let's say over 300lbs, new to exercise, etc but my first thought was whether you ate before you worked out, how long before you worked out, etc,.. some people get sick from eating right before they workout.

That doesn't really sound right to me, I would say you should talk to your doctor. You could be diabetic or have some other kind of health issue. It's not normal to get that way after cardio..

These are symptoms of low blood sugar. I suggest you get a check up with your Doctor.
Otherwise it may be that your doing too much, too soon.

Also to add.. what do you eat before you workout? Do you eat before you workout? Try filling up on healthy carb choices.. everyone is afraid of carbs but they help fuel you through your workout

You are exercising out of your fitness range/level.

That is probably the reason (after reading your responses to my questions ... thanks for that).

However, call your doc if you dial down the intensity to match your current fitness level and still have problems because there might be something else going on at that point.

I'd probably have to work my way up to 30-day shred. Maybe start with a Leslie Sansone walking DVD first or something. We all are where we are and start where we start. It's fine. Be safe!

You mentioned eating a proper dinner first, which is a good thing, but make sure it's not all protein or too low in calories. Get some whole grains in there, and maybe some fruit for short-term energy. And then do your workout no more than an hour or so later.

It may also just be the wrong time of day for you. Example: I'm a night owl by nature, so even if I have a well-balanced breakfast, if I try to work out before about 10 AM, I'm a wreck. It's just not my body's peak time. 9 or 10 PM, on the other hand? No problem.

You don't need to go see a doctor, or get checked for diabetes or up your carbohydrate intake I used to get this too when i was unfit and had never exercised before, and i'm a small, young girl without any health conditions. I would feel dizzy, nauseous and very shaky. This will go away quite quickly as your body gets used to exercising. Just take it easy and keep following good ol jillian Swimming is also a very good way to get into cardio!

JurassicKitten

Thanks a LOT everyone! I really appreciate all the helpful tips and replies I will take everyone's responses into consideration and try to find what works for me ^.^

If its been a long time since you've been in shape, or have never been in shape then its most likely just your bodies response. After I got out of the service I let myself go pretty bad. And it took about 2 months of exercise where I was coughing and feeling like I wanted to die. To the point that I was about to go get checked for asthma. But it was weird, one day I just broke through a wall and just felt like I could run forever. I would maybe build up slower and check your heart rate. Shakiness is a little strange though. So if you have insurance and a good doctor, maybe get your blood work taken.

I definitely think I should invest in a heart rate monitor. I know I have had problems in the past on the elliptical with my heart rate getting out of control way too easily. That is a good idea ^.^

This has to be one of the worst posts ever.. she does need to see a doctor. It's not normal to be "shaky and sick" after cardio. Just because you experienced this doesn't mean it's normal. The best person to advise her is not you, myself or joe blow on the internet but someone who is a medical professional.

Definitely do this.. I just invested in one recently and it's one of the best small investments I've made.

I was playing soccer today for my exercise and my max heart rate was 204 (I'm 23).. it's good to know these numbers, let's me know that I am doing all kinds of good for my heart

There could be several reasons for this. Are you well-hydrated? Are you eating enough? Are you warming up before and stretching after? Are you paying attention to your breathing?

Most importantly, have you asked your doctor about it? You might be exercising outside of your fitness level and raising your blood pressure too high too fast.

I had this problem because I wasn't eating enough calories in a day. If you have 25 lbs to lose and a deficit of 1000 calories you might want to try decreasing your deficit.
