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.
