EXERCISE GUIDELINES
1. The Warm Up Phase
This stage helps get the blood flowing around the body and the muscles working properly. It
will also reduce the risk of cramp and muscle injury. It is advisable to do a few stretching
exercises as shown below. Each stretch should be held for approximately 30 seconds, do not
force or jerk your muscles into a stretch - if it hurts, STOP.
2. The Exercise Phase
This is the stage where you put the effort in. After regular use, the muscles in your legs will
become more flexible. Work to your targeted heart rate but it is very important to maintain a
steady tempo throughout. The rate of work should be sufficient to raise your heartbeat into
the target zone shown on the graph below.
This stage should last for a minimum of 12 minutes though most people start at about
15-20 minutes

© IMPEX INC. www.marcyporo.com
22
3. The Cool Down Phase
This stage is to let your Cardio-vascular System and muscles wind down. This is a repeat of
the warm up exercise e.g. reduce your tempo, continue for approximately 5 minutes. The
stretching exercises should now be repeated, again remembering not to force or jerk your
muscles into the stretch.
As you get fitter you may need to train longer and harder. It is advisable to train at least three
times a week, and if possible space your workouts evenly throughout the week.
MUSCLE TONING
To tone muscle while on your Ski you will need to have the resistance set quite high. This will
put more strain on our leg muscles and may mean you cannot train for as long as you would
like. If you are also trying to improve your fitness you need to alter your training program. You
should train as normal during the warm up and cool down phases, but towards the end of the
exercise phase you should increase resistance making your legs work harder. You will have
to reduce your speed to keep your heart rate in the target zone.
WEIGHT LOSS
The important factor here is the amount of effort you put in. The harder and longer you
work the more calories you will burn. Effectively this is the same as if you were
training to improve your fitness, the difference is the goal.
