(HealthDay News) -- If you're working out regularly and trying to bulk up, drinking too much alcohol may hinder your efforts.

The American Council on Exercise says excessive drinking can:

  • Cause muscles to weaken because of reduced blood flow.
  • Affect hormone levels, particularly testosterone, which can lead to retaining fluids and fat.
  • Affect the liver, resulting in low blood sugar, increased fat in the blood and fatty liver.
  • Reduce oxygen supply to the brain, contributing to cell death.
