Re: Why do i always get shakey when i lift

  • You have most likely damaged some muscle cells, and the potassium that is normally inside the cell is now floating around many muscle cells.  And potassium causes your muscles to quiver instead of normally contract.

    It's why docs get all antsy when a patient's serum potassium is too high--it can cause cardiac arrhythmias.

  • Are you eating anything before you work out? It could be low blood sugar.
  • Wow this is scary!

     

     

     Yes I usually eat something before I go

    While this could happen it would not be my first guess as to why your getting shakey while lifting. Here is an artical about potassium levels and what potassium does in your body, http://www.webmd.com/a-to-z-guides/potassium-k-in-blood. You would have to be taking a large supplement in order to get to a dangerous level that could give you a heart attach.

    I also get shakey when I lift. I think I get it from raising my hr too fast and dehydration. I'll take a rest in between reps to allow my hr to lower and drink some water. Before I workout my body responds best to a small snack, apple and peanut butter, or string cheese and yogurt about an hour before the gym. If I'm feeling really shakey during lifting I'll drink a gateraid after to help with the electrolite imblance.

    I didn't mean to suggest that her serum potassium levels were high and she was at risk for a heart arrhythmia--sorry if it came across that way.  Localized high potassium, from heavy workouts, is common and in no way affects your heart.
