CONDITIONING GUIDELINES
How you begin your exercise program depends on your physical condition. If you have been inactive for
several years, or are severely overweight, you must start slowly and increase your time on the
4650 Dual-Action Recumbent Cycle gradually: a few minutes per workout.
Initially, you may be able to exercise only for a few minutes in your target zone, however, your aerobic
fitness will improve over the next six to eight weeks. Don't be discouraged if it takes longer. It's important
to work at your own pace. Ultimately, you'll be able to exercise continuously for 30 minutes. The better your
aerobic fitness, the harder you will have to work to stay in your target zone. Please remember these
essentials:
EXERCISE INTENSITY
To maximize the benefits of exercising, it is important to exercise with the proper intensity. The proper
intensity level can be found by using your heart rate as a guide. For effective aerobic exercise, your heart
rate should be maintained at a level between 70% and 85% of your maximum heart rate as you exercise.
This is known as your target zone. You can find your target zone in the table below. Target zones are listed
for both unconditioned and conditioned persons according to age.
During the first few months of your exercise program, keep your
heart rate near the low end of your target zone as you exercise.
After a few months, your heart rate can be increased gradually
until it is near the middle of your target zone as you exercise.
To measure your heart rate, stop
exercising but continue moving your
legs or walking around and place two
fingers on your wrist. Take a six-
second heartbeat count and multiply
theresults by10 tofind yourheart rate.
For example, if your six-second
heartbeat count is 14, your heart rate
is 140 beats per minute. (A six-
second count is used because your heart rate will drop rapidly
when you stop exercising.) Adjust the intensity of your exercise
until your heart rate is at the proper level.
9
Have your doctor review your training and diet programs to advise you of a workout routine you
should adopt.
Begin your training program slowly with realistic goals that have been set by you and your doctor.
Monitor your pulse frequently. Establish your target heart rate base on your age and condition.
Set up your 4650 Dual-Action Recumbent Cycle on a flat, even surface at least 3 feet from
walls and furniture.

WARM-UP and COOL-DOWN
Warm-up The purpose of warming up is to prepare your body for exercise and to minimize injuries. Warm
up for two to five minutes before strength-training or aerobic exercising. Perform activities that raise your
heart rate and warm the working muscles. Activities may include brisk walking, jogging, jumping jacks,
jump rope, and running in place
Stretching Stretching while your muscles are warm after a proper warm-up and again after your strength
or aerobic training session is very important. Muscles stretch more easily at these times because of their
elevated temperature, which greatly reduces the risk of injury. Stretches should be held for 15 to 30
seconds. Do not bounce.
Suggested Stretching Exercises
Lower Body Stretch
Place feet shoulder-width
apart and lean forward.
Keep this position for 30
seconds using the body as a
natural weight to stretch the
backs of the legs. DO NOT
BOUNCE!
When the pull on the back of
the legs lessen, try a lower
position gradually.
Floor Stretch
While sitting on the floor,
open the legs as wide as
possible. Stretch the upper
body toward the knee on the
right leg by using your arms
to pull your chest to your
thighs. Hold this stretch 10
to 30 seconds. DO NOT
BOUNCE! Do this stretch
10 times. Repeat the stretch
with the left leg.
Bent Over Leg Stretch
Stand with feet shoulder-
width apart and lean forward
as illustrated. Using the
arms, gently pull the upper
body towards the right leg.
Let the head hang down.
DO NOT BOUNCE! Hold the
position a minimum of 10
seconds. Repeat pulling the
upper body to the left leg.
Do this stretch several times
slowly.
Remember always to check with your physician before starting any exercise program.
Cool-Down The purpose of cooling down is to return the body to its normal, or near normal, resting state
at the end of each exercise session. A proper cool-down slowly lowers your heart rate and allows blood to
return to the heart. Your cool-down should include the stretches listed above and should be completed
after each strength-training session.
Bent Torso Pulls
While sitting on the floor,
have legs apart one leg
straight and one knee bent.
Pull the chest down to touch
the thigh on the leg that is
bent and twist at the waist.
Hold this position at least 10
seconds. Repeat 10 times
on each side.
