Today, Thanksgiving and tomorrow with all the leftovers, there will be a ginormous amount of eating. Even if you only nibble through the day, you still will be consuming larger than usual amounts of calories because of socializing, and well, there's food everywhere.
Before you feast on that fine meal, go for a trek or trot: walk or run. If you can't do it before hand, if turkey dining is early enough, go afterwards. The gyms are closed but you can still get outside smell some fresh air, burn some calories, and if the weather is nice where you live, enjoy some beautiful scenery. If you have relatives or friends in town, take them with you. The trek or trot is a great way to get some quality time together, and again burn some calories. It's a two-for-one!
Here's one of the sexiest men alive on a trot with his dad Thanksgiving morning.
