Staying in shape over the winter can be tough. You're trapped inside. Eating comfort food. Stuffing yourself at holiday parties like you're going to the electric chair. Sweatshirts and coats hide your growing gut, so you just let it go for a few months. Which means you have to fight to get it off before beach season.

To keep the Winter Flab off you this season, I spoke with Anthony Slater, Head Performance Specialist at the Core Performance Center. (Those are the guys I'm giving away the fitness prize pack with this week.) He has some great tips for keeping you strong and trim during the colder months.

All are designed to be done indoors, and with minimal or no equipment. And if you're a fitness rookie, you can click the links to get video instruction showing you exactly what to do, so you're prepared to hit the beach or links the minute things warm up.

Here's what Slater recommends:



Put a Russian Twist in Your Training:
Don't worry guys, the Russian Twist isn't a move that Warren Sapp is doing on Dancing with the Stars or a new kind of martini—it's simply a movement you can do on a stability ball that will help with everything from preventing injury to improving your golf swing.





It's Your Turn to Be Mr. October:
If watching playoff baseball has made you wish you were in the World Series, head to your backyard to do Lateral Bound Stabilization, a fancy word for improving your explosiveness and working your hips and legs. You'll be stealing bases in no time.




Add Some Stability to Your Life:
When we say add "stability", we aren't throwing in the towel on your single days. We mean using a physioball to add a level of intensity to your push-ups that will force you to stabilize your core and targeting your chest, arms, and abs all at once. Building a body women want starts from the core, so there's no better place to start.




Stretch Your Limits:
Most guys hate to stretch and avoid doing so at all costs, but stretching is a valuable tool to both build flexibility and prevent injuries long term. If you skip everything else, master the World's Greatest Stretch, a simple movement that allows you to stretch your hips, hamstrings, groin, lower back and quads all at once.


Refuel After You Workout:
When you train, you deplete your energy stores, breaking down muscle and dehydrating your body. So after you leave the gym or finish your run, make sure you eat a snack to trigger your body out of a state of breakdown and into a state of recovery. Shakes are best because they contain protein that your body can easily digest, but chocolate milk is also a bachelor-friendly option to refuel after a tough training day.
