5 ways to get in shape this Winter

While on active duty, maintaining some level of fitness is essential. It is literally a requirement of your everyday life. But once it's not required, it's very easy to find yourself completely out of shape and overweight.

After giving yourself a look in the mirror, you'll probably pine for the days of old — the days of tone and definition. Well, it's never too late; here are a few ways to get in shape fast.

Full-body workouts are a hot topic these days

Full-body training

Full-body training is a form of weightlifting that has been gaining lots of popularity in the fitness world recently, and it's exactly what it sounds like. Throughout the course of a single session, you'll target each muscle group, getting a pump for your entire body.

Despite its recent popularity, full-body training has been around for ages. Design a routine that pays extra attention to your trouble spots and you should see some serious results very fast.

Bro-Splits

We all know what bro splits are, even if we don't necessarily know them by that name. A bro-split is a routine that focuses on your back, your biceps, your chest, and your triceps. This technique, too, has been around for far longer than most of us have been alive.

There's an obvious benefit to this: it's simple and it'll get you looking swole quickly. That being said, there's must more to being fit than looking fit. If you're only in it for the beach bod, this might be the method for you.

CrossFit

Ahh, the much-maligned CrossFit. If you're a CrossFit junkie, then you already know that everyone has an opinion on the recent trend. In the blink of an eye, CrossFit has managed to blossom into a full-blown sport that is beloved and practiced worldwide. Truthfully, CrossFit is an amazing workout and will give you great results... even if the exercises look a little funny at times.

Marathon training

Running is one of the most time-tested ways to lose weight and training for a marathon is one of the most certain ways to commit to running many miles with regularity. There's simply no way to do all the running you need to prepare for a marathon without slimming down.

As an added bonus, committing to a run (marathon or otherwise) forces you to get your diet together. You simply won't be able to go the distance without a proper diet.

Bodyweight exercises have been around since the beginning of time. Maybe it's time you gave it a try.

Calisthenics 

Can you do 40 push-ups without stopping? How about 40 dips within 2 minutes? How about 40 pull-ups in that same timespan?

Chances are, especially if you're a recently retired/separated veteran, you can do the push-ups with no issue. The others, however, are going to be more challenging. Put together a quick, fun, and sweaty, circuit-style workout of your own and see the combined benefits of body weight movements and aerobic exercise.
