Someone sent me this article today (go read it then come back) hoping it would answer prayers to make the gym a more bearable place.
So, according to this alcohol reduces your risk of blood clotting while you work out, which is no surprise because it's a blood thinner just like aspirin and garlic.
What they fail to mention is that alcohol will certainly reduce your ability to work out efficiently. You need to have intensity and endurance when you workout and alcohol inhibits both of those processes.
I wish pop-science nutrition articles would discuss entire stories and not just catchy rhetoric. Perhaps you should eat a clove of garlic before the gym rather than going to the pub if your concerned about having a heart attack in the middle of you elliptical workout!
