The thought of doing mountain climbers may bring you back to your elementary physical education class, but your P.E. teacher may just have known what he was doing. Mountain climbers are actually a great strength training and cardiovascular exercise mixed into one. They help increase your endurance, which is were the cardiovascular workout comes in, and they work to increase your core strength and upper body strength.

How to do a mountain climber:
1. Get into a normal push up position on your feet and hands. Be sure that your back is straight and your abdominal muscles are contracted the whole time.

2. Bring the right knee up to the chest.

3. Extend the right leg back out at the same time you start bringing in your left knee to your chest.

4. Keep quickly alternating your legs. You can do mountain climbers for a certain period of time as 5 minutes or you can do a set of 100 of them.

If you want to make your mountain climbers a lot harder, try doing them with your hands on a balance board. The balance board gives instability which makes you work that much harder to stay balanced during the exercise. Mountain climbers with a balance board will have you feeling your abs the next day. You can also choose to add ankle weights as well to make the exercise more challenging for you.

When performing mountain climbers, your abdominal muscles should be engaged the whole time. When you bring your knees up to your chest, there should be a slight twist that also helps to slim the abs as well. Also, since you are in a push up position the whole time, your upper body such as your shoulders, triceps, and upper back is working to keep you supported, which means they are getting a workout as well.

Mountain climbers, although they may seem silly at first, are a great way to get a strength workout as well as a cardio workout for your entire body.

Jumping jacks may not be a popular choice for some people, but they are a very effective exercise that are not just for warm ups. Jumping Jacks can easily be integrated into a cardiovascular workout as well as a strength training workout.

Have you ever tried to do 50 jumping jacks in a row? How about 100? I mean actual jumping jacks and not the cheap version were you only move your wrist back and forth and your legs never leave the ground. If you haven't tried this many jumping jacks in a row before, go ahead and try it now. You will see exactly how much of a cardio workout that you are getting.

If you do a jumping jack correctly you can also get a great workout to strengthen your muscles. By keeping your abdominal muscles contracted the whole time, you are getting a core workout as well. Jumping jacks work your entire body and when you add weights, it takes it to the next level.

Here is how to do a jumping jack:
1. Stand with your arms down by your sides and your feet together. Knees should be very slightly bent and your abs should be contracted.
2. Bend your knees as you jump, kicking your legs out to the sides so that they are wider than shoulder length. At the same time raise your arms up over your head so that the two hands meet right over your head. Your elbows should be slightly bent.
3. Jump your legs back together as you bring your arms down back to starting position.
4. Do not take a break and continue the steps until you have reached your desired repetition.

To add some challenge to your jumping jacks, you can wear weighted gloves or add a light dumbbell to the workout. This makes the exercise more of a strength training maneuver as well.

Remember that although jumping jacks do make a great warm up exercise, the intensity can be increased and they can also make a great addition to a cardiovascular or circuit training routine.

As New Year's resolutions fade into the distance and you get back into the rhythm of work, play and errand-running, sticking with the fitness mantra may become a challenge. Even the most determined can have an 'off' day, which soon turns into two, then three, then an entire week of 'just couldn't make it to the gym.' This is why you need a plan that helps you sneak in some fitness activities without the formal trip to the gym.

A few simple changes to your daily routine can help you burn extra calories; by the end of the day, you could have burned off the equivalent of a mini-workout - and all without breaking a sweat. Here are some easy ways to get that metabolism going and keep up with your fitness resolutions in those busy weeks ahead:

Socialize on the go
If you need 10-15 minutes to catch up with a coworker or associate, consider taking it outside. Walking will ease stress and tension and give you both a chance to enjoy the great outdoors. Put on your walking shoes if you're heading out on icy streets or on a rainy day; you'll be well on your way to quick calorie burn.

Go on a Coffee run, Literally
Choose a coffee shop that's at least a 10-minute walk from the office and speed walk or jog your way to the counter. The quick break in the middle of the day will give your body a chance to shift gears, and the fresh air will do you good. Just make sure you stick with that no-fat, no-whip, sugar-free latte to avoid negating your hard work.

Shoot Hoops Before Dinner
Remember when shooting some hoops or playing tennis against the wall at home was your usual routine before dinner? Relive those childhood memories as you transition from the work day to the evening. To challenge your body, get out of the rut of sitting in your office and then sitting at the dinner table. You'll also burn up some extra calories as you de-stress after your busy day.

In previous weeks, we've discussed the importance of exercise. It's time to take the discussion one step further. This week we'll tackle the number one reason why people don't exercise. Or should that be the number one excuse people use for not exercising? What could that be? Might it be that people claim they're too busy to exercise? That's exactly it. In fact, I've used that excuse several times myself. But, as you'll see from this week's entry, no one is too busy for exercise.

A few weeks ago, we spoke about how exercise didn't have to be running or jumping jacks. We also discussed how exercise can be broken down into smaller timeframes. But what you may be surprised to learn is that exercising can take place throughout your day. While completing everyday activities, you can get the exercise you need. This is what I love about exercise.

Over the years, I've learned several ways to incorporate exercise into my busy day. The following are just a few of the many, many ways you too can incorporate exercise into your life.

• Park far away from your destination
• Walk whenever possible
• Take the stairs
• Walk up escalators
• Skip the car wash and do it yourself
• Visit a farm that lets you pick your own produce
• Go shopping at the mall, rather than online

I told you that you had time for exercise. You just need to think about what happens throughout your day and how you can turn those activities into exercise. For example, search the web for exercises that can be done at your desk. While you're speaking with clients, you can be toning your arms and burning calories.

Exercise is possible. Best of all, when you follow these tips, you'll never even know you're exercising. Did I mention this is a great way to spend more time with your family? Walk your kids to school, take your kids shopping or incorporate calorie burning activities into family night.

Plain and simple, exercise doesn't have to involve a gym bag. You can exercise anywhere and at anytime.
