| Muscle Spasms During Contraction
sup cf
During some of my lifts I have had this odd feeling of my muscle spasming during the contraction.
For instance, when I haven't done sit ups in a while my body jerks around when I am coming up, as if I was having a mini seizure on my abs.
Has anyone had these muscle spasms or could tell me what they are from?
thnx |
