Today is the first day of spring, yet it's still a little too cold out in some parts of the country to fully embrace an outdoor workout. Fortunately, you can always go on fitness journey right in your gym!!
As far as suggestions go, my only one is to try to get to the gym during some of its least busy times. That's because the workout -- er, I mean, fitness journey -- you're about to embark on requires the use of several different machines. So, going on the assumption that you took my advice, let's start the workout.
Run the Roads. Start by walking two or three minutes on a treadmill to warm up. Then, once your body feels like the blood is pumping, ramp up the intensity. At the same time, increase the incline. Blast out five minutes of running, doing your best to pretend you're pounding the actual pavement (just don't wave at any invisible friends that may drive by in their make believe cars).
Bike Up the Hill. Without taking a break, go right from the treadmill to a stationary bike. Set the resistance to a higher level than what you are accustomed to. Picture yourself steadily biking your way up a steep hillside as you pedal for five minutes.
Climb the Mountain. Jump on the stepper and get those legs moving. It may not be as scenic as hiking up the side of a good sized rock, but it will feel about the same on your legs and lungs. Go for a hard five minutes.
Ski the Summit. Now that you've hiked up the mountain, you can cross-country ski your way across the top of it. While it doesn't exactly mimic the motion of cross-country skiing, an elliptical machine is a reasonable facsimile. Finish your workout with five hard minutes.
This intense twenty-minute workout is enough to get your heart pumping good and hard. Even if you can't get into the whole imagination part of it, the constant jumping from work station to work station will certainly keep you from getting bored.
