When I was a kid, my family spent most of our summer at a cabin in the northern part of our state. Inevitably, one of my sisters and I would be covered in mosquito bites, while the rest of the family escaped that itchy fate. My mom used to say that my sister and I had "sweet blood." Turns out, she wasn't too far off base.

Among other factors, tiny little blood-suckers such as mosquitoes are drawn to the carbon dioxide and lactic acid we excrete. While we all release carbon dioxide and lactic acid larger people and pregnant women have higher amounts. You're also likely to have a higher level of lactic acid in your sweat just after exercising. High body temperature is also a beacon to mosquitoes. Floral scents (perfumes, etc.) may also be a draw as well as dark colored fabrics.

When we're pumping iron at the gym, working our muscles to the max, extending every bit of energy we have to the point that sweat is pouring down our temples, the only thing we really want is relief--sweet, sweet rest. We want to stop what we're doing, put the weight down, have a long, cold sip of water and relax. But is that what we should do? Guess again.

Actually, there's a lot of research out there that shows that the best way to recover after or during a workout is not by resting at all--it's by continuing to work you muscles in a less-strenuous way. You may have heard of this kind of 'rest'--it's called active rest (or active recovery in some circles.)
