I have a workout of all body weight resistance exercises (push-ups, crunches, lunges and squats and stuff) and after doing it I feel really sick for the next hour.

When I do squats and lunges my knees make a cracking sound, like I'm cracking my knuckles but not once at the beggining but over and over each repetition, this happens (to a much lesser degree) in my elbows doing push-ups too.

In about every exercise after while the limbs which are being worked out begin to tremble like crazy.

I wondering if I should be exercising at all. Is my body telling me I'm doing something wrong or are these things normal?

How long have you been doing this routine, and how long do you do it for every day?

You know what happens when you crack your knuckles?

what happens is that there is a space between the knuckle bones and cracking them realigns them into the space. so doing it once is all fine and good, but if it does it every rep, then something is wrong with the joint.


I would advise you to stop the routine and see a doctor immediately.

A couple weeks, it's about a half hour of exercise, maybe a little more.

If its been doing that for 2 weeks, that is definately not normal.
I agree with B_Duggan, you should see a doctor and see whats up with that..it could just be a slight problem that could be fixed with physical therapy..but if you continue this you might do some unwanted damage.
